Bionic Electric Shoe With Rotatable Heel And Forefoot
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric roller skates have non-bendable shoe soles, preventing users from maintaining a normal walking posture, making them impractical for navigating complex urban environments and limiting their usability to those with roller skating experience.
Innovation Solution
Bionic electric power shoes with rotatable shoe heel and forefoot parts, featuring multiple rotating wheels and a motor-driven transmission system that allows for a natural gait cycle, ensuring stability and ease of use on various terrains by maintaining contact with the ground through a combination of rotating wheel racks and arc-shaped holes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the shoe sole is made non-bendable and in one piece, then the structural strength is improved, but the user cannot maintain a normal walking posture
Solution Approach 1:
The shoe sole is divided into a heel part and a forefoot part that can rotate relative to each other. This segmentation allows the shoe to bend and adapt to the natural walking gait cycle, enabling users to maintain a normal walking posture while preserving overall structural integrity through the rotational connection mechanism.
2Ease of manufacture
If the shoe sole is made non-bendable, then the manufacturing complexity is reduced, but the adaptability to complicated urban roads is worsened
Solution Approach 1:
The shoe sole incorporates a rotational connection between the heel part and forefoot part, transforming the static non-bendable structure into a dynamic one. This allows the shoe to adapt its shape and angle according to different walking conditions and road surfaces, greatly improving adaptability to complicated urban environments while remaining manufacturable.
3Ease of operation
If the shoe heel is lifted up during walking, then the walking naturalness is improved, but the middle wheels may get off the ground alone, reducing stability
Solution Approach 1:
The arc-shaped holes are designed in advance to guide the movement of the first rotating shaft. When the shoe heel is lifted during natural walking, the arc-shaped holes pre-determine the path and timing of wheel engagement, ensuring that wheels are lifted in a controlled sequence rather than allowing the middle wheels to get off the ground alone, thus maintaining stability.
4Ease of operation
If the middle wheels get off the ground alone, then the front wheels bear high pressure, but the service life of the second rotating wheel racks is shortened
Solution Approach 1:
The arc-shaped holes act as an intermediary mechanism between the heel lift action and the wheel engagement. They distribute and regulate the pressure transmission, preventing the front wheels from bearing excessive pressure when the heel is lifted, thereby extending the service life of the second rotating wheel racks while preserving natural walking motion.
