Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If shoe spikes are used on hard surfaces for anti-slip purposes, then anti-slip performance is improved, but comfort deteriorates and shoe spikes are easily damaged
Solution Approach 1:
The patent employs a rotatable anti-slip mechanism that can dynamically switch between different friction surfaces (first friction surface and second friction surface) depending on the terrain conditions. This dynamic adaptability allows the shoe to provide effective anti-slip performance on icy surfaces while maintaining comfort on hard surfaces by selecting the appropriate friction surface, thus resolving the contradiction between anti-slip reliability and operational comfort.
2Reliability
If dual-axis connection is used for anti-slip devices, then anti-slip function is provided, but assembly convenience deteriorates
Solution Approach 1:
The patent segments the anti-slip device into distinct components (mounting seat, rotatable mechanism, friction surfaces) that can be independently manufactured and then assembled. This segmentation approach simplifies the assembly process compared to dual-axis connections, while maintaining the anti-slip function through the rotatable mechanism that allows switching between different friction surfaces based on terrain requirements.

AI summary
The present application relates to a rotatable anti-slip device (1) and an all-terrain anti-slip sole, wherein the anti-slip mechanism (12) can turn over relative to the mounting seat (11) by providing a rotation part (122). Specifically, by providing a sphere (123), the rotating shaft (124) can rotate along the spherical surface. At the same time, the rotating shaft (124) is arranged between the sphere (123) and the friction part (121), and the rotating shaft (124) can limit the rotation direction, so that the friction part (121) can be turned over along the rotating shaft (124). The friction part (121) has a first friction surface (125) and a second friction surface (126). Users can adjust the friction part (121) according to different terrains to meet the anti-slip needs of different terrains, which effectively improves the anti-slip effect on different terrains. Additionally, the anti-slip device can be easily and conveniently replaced, and the anti-slip function of the shoes will not be lost due to accidents or damage.
