I think all your ideas are fantastic and you’ve done a great job! Among the three proposals, I prefer the first one over the latter two—probably because it has lower costs and is more user-friendly and intuitive for the elderly. I’d like to put forward a few suggestions, hoping they’ll be helpful to you.
1. Optimization Suggestions for the “Intergenerational Bridge · Water and Warmth” Project
Adapt to an Ultra-Simple Interface for the Elderly
1.A large “One-Click Water Request” button to reduce operation levels.
2.Automatic geolocation recognition to minimize input steps.
3.Voice assistance support: “Little Assistant, help me call a volunteer to deliver water.”
Form a Closed Loop of “Light Social Interaction + Light Services”
Beyond water delivery, expand to:
1.”One-Minute Greeting” – Volunteers video-call the elderly to check in.
2.Monthly community exchange meetings to promote real connections.
Enhance the “Water Cradle” System
1.Adopt a foldable structure to reduce floor space when not in use.
2.Add water bottle buckles and non-slip pads to prevent shaking during transportation.
3.Introduce a mini half-frame “Water Cradle Lite” – not a wheeled cart, but a lightweight “stable frame” with handles. Elderly users can “drag/slide” it by holding the side handles, saving 40%-50% more effort than carrying a water bottle.
