Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the battery pack is secured at the raised rear edge of the base plate to increase power capacity, then the energy storage is improved, but the longitudinal length of the device increases causing awkwardness and discomfort during stair climbing
Solution Approach 1:
The battery pack is repositioned from the longitudinal rear edge to the transverse width direction of the base plate. This dimensional change allows the battery to be secured at the transverse edges rather than extending the longitudinal length, thereby maintaining energy storage capacity while reducing the device's longitudinal footprint for easier stair navigation
Solution Approach 2:
The base plate is designed with pre-integrated battery mounting structures at its transverse edges, allowing the battery pack to be securely installed in the optimized position before assembly. This preliminary design ensures the battery occupies space that does not interfere with longitudinal dimensions, preventing the length extension problem before it occurs
2Stability of the object's composition
If the distance between the two feet is increased to improve skating stability, then the skating stability is improved, but the device contour exceeds the shoe contour causing awkwardness and inconvenience
Solution Approach 1:
The device incorporates adjustable components that allow the effective skating surface and foot positioning to be dynamically modified. This enables the wearer to optimize foot distance for stability while maintaining a compact base contour that fits within shoe dimensions, resolving the conflict between stability requirements and shape constraints
3Adaptability or versatility
If large diameter wheels are used to improve obstacle-overcoming capability, then the obstacle-overcoming capability is improved, but the device complexity and size increase
Solution Approach 1:
The wheel diameter is optimized to a specific parameter range that provides sufficient obstacle-overcoming capability without excessive size. Additionally, the wheel mounting configuration and base plate geometry are adjusted to accommodate these wheels within compact dimensions, maintaining adaptability while controlling device complexity

AI summary
A wearable motorized device comprising a shoe bracket, which has a ring-shaped structure and can be fastened to the middle part of a shoe; a wheel, which rotatably supports the shoe bracket to enable lateral skating and longitudinal walking; a driving motor, which rotationally drives the wheel; and a battery pack, which powers the driving motor. The wheels are not coaxially installed on the two sides of the shoe bracket to drive the wearer's longitudinal skating, but are installed on the ring-shaped shoe bracket, which can be fastened to the middle part of the shoe, to support the wearer's lateral skating and longitudinal walking. This way, the wearer can position his/her legs apart during skating; such that the skating stability is improved. Moreover, its general contour does not significantly exceed the contour of the shoe in the longitudinal direction, thus it will not strain the wearer when ascending or descending stairs. Therefore, a wearable motorized device with high skating stability and ease of use can be achieved.
