Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complex lock system with movable abutment members is used to immobilize wheels, then the wheels can be effectively locked, but the device becomes difficult to manufacture and requires complex assembly
Solution Approach 1:
The wheel lock device is divided into two separate loops (first loop and second loop) that can be independently manufactured and then assembled by connecting them together. Each loop independently engages with its corresponding wheel, simplifying the manufacturing process while maintaining effective wheel immobilization through the combined action of both loops
Solution Approach 2:
The patent combines the functions of multiple abutment members into a single integrated loop structure. Each loop incorporates multiple engagement points (first abutment, second abutment, third abutment) that work together to prevent wheel rotation, eliminating the need for separate movable abutment mechanisms while achieving the same locking effect
2Reliability
If a fixed rigid wheel lock structure is used, then the wheels can be securely locked, but the device cannot adapt to different skate configurations and wheel sizes
Solution Approach 1:
The loops are designed with flexible materials that allow them to dynamically adjust their shape and size to accommodate different wheel configurations. The loops can stretch and conform to various wheel sizes and skate frame distances, maintaining secure engagement through elastic deformation while adapting to different geometries
Solution Approach 2:
The device utilizes materials with specific elastic properties that allow the loops to change their physical parameters (shape, size, flexibility) based on the wheel configuration. The flexible material enables the loops to stretch and conform to different wheel sizes and distances between wheels, maintaining effective engagement across various skate types
3Adaptability or versatility
If elastic material is used for the loops to provide flexibility, then the device can adapt to different configurations, but the structure may lack the strength to effectively prevent wheel rotation
Solution Approach 1:
The loops are constructed from flexible materials with optimized elastic properties that provide both the necessary flexibility for adaptation and sufficient strength for wheel constraint. The material selection balances these two requirements, allowing the loops to stretch and conform to different configurations while maintaining the structural integrity needed to prevent wheel rotation

AI summary
A wheel lock device for roller skates is disclosed. The device comprises two loops connected by a flexural section, defining two apertures wherein the wheels of the roller skate are placed. The flexural section, made of an elastic material, allows the device to be stretched and fitted over the wheels. The device may include inner or outer chocks proximate to the loops to prevent rolling. Overhangs extending from the inner wall of the aperture prevent the device from sliding off the wheels. Inner and outer pull tabs provide improved grip for installation and removal. The device may have a closed face to protect the wheels from debris. The device is a monolithic structure made of a flexible material, allowing for adaptability to different skate configurations.
