Product 1: “Neighborhood Tai Chi Disk” – Two-Person Collaborative Balance Training Equipment

1. Safety Protection Design

The main body of the equipment is a circular platform with a diameter of 2 meters, covered with a 2cm-thick non-slip rubber mat (friction coefficient ≥ 0.8). A 15cm-high fall-proof baffle (soft-covered material) is installed around the edge to prevent falls from unstable standing.

A hydraulic buffer device is equipped under the platform, with a maximum tilt angle not exceeding 10°. Even if unbalanced, it can reset slowly to reduce impact damage. Two arc-shaped armrests (height 0.85m, grip diameter 3cm) are set on each side, wrapped with non-slip foam for easy support at any time.

A gravity-stabilized base (weight ≥ 50kg) is added at the bottom to prevent the equipment from tipping over. A crutch placement slot (depth 15cm) is reserved to meet the needs of elderly people with limited mobility.

2. Social Interaction Functions

It supports 2 people to use simultaneously. The platform is divided into two independent left and right areas, which can rotate synchronously or in reverse. With preset Tai Chi movement guidelines (footprint marks on the ground + soft light prompts), it realizes “two-person synchronous Tai Chi practice”.

A built-in voice interaction module supports a “password synchronization” mode (e.g., “Start – Turn left – End”), guiding the two to cooperate with the rhythm. After completing a set of movements, the device automatically broadcasts “Cooperation successful! Tacit understanding score: 95 points” to enhance interaction fun.

A detachable small tabletop (installed between the armrests) is provided. When not in use for exercise, it can hold teacups and chessboards, transforming into a neighborhood communication table that meets both fitness and social needs.

3. Body Adaptability Design

The exercise intensity is adjustable. Switch between “low speed/medium speed” modes via a large button (diameter 5cm) next to the armrest. The low-speed mode (rotational speed ≤ 5 rounds/minute) is suitable for elderly people of advanced age, while the medium-speed mode is adapted for those with exercise experience.

The platform’s rotation resistance adopts a progressive design, with minimal resistance at startup to avoid muscle strain from sudden exertion. A built-in heart rate monitoring sensor (at the armrest contact position) automatically reduces the rotational speed and gives a voice reminder to rest when the heart rate exceeds 120 beats/minute.

Product 2: “Old Friends Collaborative Bar” – Multi-Person Linked Upper Limb Training Equipment

1. Safety Protection Design

The main body is made of stainless steel (rust resistance grade ≥ 304). The crossbar height is set at 1.1m (suitable for sitting and standing postures), with a non-slip rubber coating on the surface. The spacing is designed according to ergonomics (0.6m) to avoid crowding and collisions.

Each training position is equipped with an adjustable seat (height 0.45-0.55m), featuring a detachable safety belt and a non-slip cushion. Space is reserved under the seat for crutches and walkers. Elastic floor mats (thickness 3cm) are laid on the ground to reduce impact force when falling.

The equipment has a built-in overload protection device that automatically locks when the pulling force exceeds 30kg, preventing joint damage from excessive force. An emergency call button (linked to the community service center) is installed next to each training position for help in emergencies.

2. Social Interaction Functions

It supports 3-4 people to use at the same time. The crossbars are connected by a linkage shaft; when one person pulls the crossbar, the crossbars at other positions move slightly synchronously, forming an interactive mode of “multi-person collaborative force” suitable for neighborhood group training.

A built-in points system records the collaboration completion of each training session (e.g., “Four people pull synchronously 10 times, earn 20 points”). Points can be exchanged for small gifts (such as laundry detergent, physical examination coupons) in the community to stimulate sustained participation enthusiasm.

A foldable small blackboard is set between the crossbars, which can be used to write training slogans, activity notices, or as a neighborhood message board to enhance social connection. A Bluetooth speaker is equipped to play square dance music and health popularization audio, creating a lively group atmosphere.

3. Body Adaptability Design

The pulling force can be flexibly adjusted by adding weight blocks (5kg per block, maximum weight 20kg), adapting to elderly people with different muscle strength levels – from “light pulling force for joint activity” to “medium pulling force for muscle strengthening”.

Training movements are designed with a slow “pull-release” rhythm. A paper operation guide (large font + pictures) is attached next to the equipment, and voice broadcast of operation steps is supported (e.g., “Slowly pull the crossbar to the chest, hold for 3 seconds, then slowly release”) to lower the learning threshold.

Product 3: “Joyful Walk Companion” – Multi-Person Accompanied Lower Limb Training Equipment

1. Safety Protection Design

The equipment body adopts a rounded design (corner radius ≥ 5cm) to avoid sharp protrusions. The pedals are ≥ 20cm wide with non-slip patterns on the surface, and buffer springs are installed under the pedals to reduce impact force when landing and protect knee joints.

Each training position is equipped with double-sided armrests (height 0.9m) that can be adjusted at an angle of 0-15°, adapting to different heights and standing postures. The pedal stroke is controlled within 30cm to prevent imbalance caused by excessive strides, and a limit device is set to avoid over-swinging of the pedals.

A stable base (weight ≥ 60kg) is added at the bottom to ensure no shaking during use. Rest benches are placed around (spacing ≤ 5m) for the elderly to rest between training sessions. The benches are equipped with sunshades and cup holders to enhance comfort.

2. Social Interaction Functions

It adopts a side-by-side layout (3-4 training positions), allowing neighbors to communicate face-to-face during training. Meanwhile, the synchronized swing design of the pedals creates a “walking together” scenario, relieving the boredom of training alone.

Built-in interesting interactive games are displayed on the small screen next to the armrest (font size ≥ 24pt), such as “Step Count Competition” and “Synchronization Rate Challenge”. For example, “Walk synchronously with friends beside you for 30 seconds to win the ‘Tacit Partner’ title”, enhancing interaction fun.

It supports connection to community elderly activity groups. Training data (step count, duration) can be synchronized to the group, forming a “daily check-in” interaction. This facilitates mutual encouragement and training appointments among neighbors, expanding their social circles.

3. Body Adaptability Design

The swing speed is adjustable (0.5-1.5m/s). The low-speed mode is suitable for elderly people with joint pain or poor balance, who only need slight swings to activate their lower limbs. The high-speed mode is adapted for elderly people in good physical condition to meet intensive training needs.

The pedal height can be fine-tuned (±3cm) to fit the stride length of elderly people of different heights. An optional “sitting training” accessory (additional seat can be installed) is provided, allowing elderly people with limited mobility to complete lower limb swing training while sitting, catering to groups with different mobility levels.
