Solution Overview
Problem
Conventional personal mobility devices are heavy and large, lacking portability, and playthings with inflatable bodies are unstable and unsuitable for transporting objects.
Innovation Solution
A moving device with a body unit that can be inflated or deflated, featuring a drop-stitch structure and wheels, allowing for improved portability and stability to transport objects, with the drop-stitch structure providing tensile forces perpendicular to the load direction to maintain shape and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If conventional personal mobility devices are used, then they can transport objects, but they are heavy and large, lacking portability
Solution Approach 1:
The body unit transitions from a rigid structure to a dynamic inflatable structure that can change its physical state between inflated (stable, load-bearing) and deflated (portable, stored) conditions, resolving the contradiction between stability for transport and portability for carrying
Solution Approach 2:
The physical parameters of the body unit (volume, shape, rigidity) are changed by injecting or discharging fluid, allowing the device to adapt between requiring stability for object transport and being compact for portability
2Ease of operation
If inflatable playthings are used, then portability is improved, but they lack stability and cannot transport objects
Solution Approach 1:
The body unit uses an inflatable shell structure that provides both portability when deflated and stability when inflated, eliminating the need for heavy rigid frames while maintaining structural integrity for object transport
Solution Approach 2:
Fluid injection and discharge mechanisms enable the body unit to transition between inflated and deflated states, providing on-demand stability for object transport while maintaining portability when not in use
3Reliability
If the body unit is inflated to provide stability, then it can transport objects, but it increases in size and reduces portability
Solution Approach 1:
The inflatable body unit dynamically adjusts its volume and structural properties based on operational needs, being compact for storage/transport and expanded for stable object carrying, resolving the size-stability contradiction
