Power Shoe Transmission Layout for Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric roller skates have low stability due to a long distance between the shoe soles and the ground and small wheel tread, making them unsafe for general use, especially for those without roller skating skills.
Innovation Solution
Power shoe devices with rotating wheels and a motor-driven transmission system that includes multi-stage speed reduction structures on rotating wheel racks, reducing the vertical size of the transmission device and allowing closer placement to the ground, along with adjustable wheel treads for improved stability and mobility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If transmission structures are made compact, then the distance between vamps and ground can be shortened, but the wheel tread size is limited
Solution Approach 1:
The transmission device is repositioned from a vertical arrangement (below the shoe sole) to a horizontal arrangement (at the rear end of the shoe sole, alongside the rotating wheels). This dimensional change allows the transmission structures to occupy horizontal space rather than vertical space, enabling both short distance between vamps and ground and adequate wheel tread size simultaneously
2Stability of the object's composition
If wheel tread is increased to improve stability, then the distance between vamps and ground increases, but if wheel tread is decreased to reduce distance, then stability decreases
Solution Approach 1:
The transmission device is relocated to the rear end of the shoe sole in a horizontal arrangement, allowing the rotating wheels to be positioned closer to the ground (reducing distance from vamps to ground) while the wheel tread can extend horizontally to provide adequate stability. The transmission structures now occupy horizontal space alongside the wheels rather than vertical space below the sole
3Volume of stationary object
If multi-stage speed reduction structures are added to reduce transmission device volume, then the vertical space is reduced, but the structural complexity increases
Solution Approach 1:
The multi-stage speed reduction structures are arranged horizontally at the rear end of the shoe sole alongside the rotating wheels, rather than vertically below the sole. This dimensional relocation allows the complex multi-stage transmission structures to be distributed in horizontal space, reducing their vertical footprint and enabling the vamps to be positioned closer to the ground while maintaining adequate wheel tread size
