Swing Wheel Locking Mechanism for Shared-Axle Wheel Structures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wheel locking devices are too complex and not suitable for wheel structures where the wheel bodies are fitted in a rotatable manner on both ends of a shared axle, such as in water spray seats, due to their design requiring configuration on the periphery of the wheel body.
Innovation Solution
A swing type wheel locking device with a pivoting axle end and a swing section that can be angled to lock or release the wheel, featuring a clamping convex part that fits into positioning concave parts on the wheel face, allowing for orthogonal swing direction and rotational direction, simplifying the structure and operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a pressing mechanism is added on the circumference or rim of the wheel to achieve locking function, then the wheel locking capability is improved, but the device complexity increases
Solution Approach 1:
The patent combines the locking function and the support function into a single integrated component. The swing type wheel lock component serves dual purposes: it locks the wheel when in the locked position and supports the wheel body when in the support position, eliminating the need for separate pressing mechanisms and reducing overall device complexity
Solution Approach 2:
The swing type wheel lock component is designed with multi-functionality, acting as both a locking mechanism and a support structure. This universal component can perform multiple functions (locking and supporting) depending on its angular position, thereby reducing the number of components needed and simplifying the overall device structure
2Reliability
If the wheel locking device is configured on the periphery of the wheel body to achieve locking function, then the locking capability is improved, but the adaptability to different wheel structures deteriorates
Solution Approach 1:
The swing type wheel lock component is designed to be universally applicable to different wheel structures. It can function as a locking mechanism for wheels with peripheral configuration and as a support component for wheels with shared axle configurations, making it adaptable to various wheel body types including water spray seats
Solution Approach 2:
The swing type wheel lock component employs dynamic positioning with multiple angular positions. It can swing between a locked position for securing the wheel and a support position for supporting the wheel body, providing dynamic adaptability to different operational requirements and wheel configurations
3Reliability
If multiple components are used to achieve both locking and support functions, then the functional completeness is improved, but the manufacturing and assembly cost increases
Solution Approach 1:
The patent merges the locking component and support component into a single swing type wheel lock component. This integration reduces the total number of parts, simplifying manufacturing processes and assembly operations while maintaining both locking and support functions through the component's multi-position capability
4Reliability
If a complex pressing mechanism is used to achieve reliable locking, then the locking reliability is improved, but the ease of operation deteriorates
Solution Approach 1:
The swing type wheel lock component utilizes simple angular movement for operation. The user can easily swing the component between locked and support positions without complex pressing actions, improving ease of operation while maintaining reliable locking through the positive engagement of the locking surfaces

AI summary
A swing type wheel locking device includes a wheel axle and a pivoting part. A wheel body has an outer wheel face and an axle hole fitted on the periphery of the wheel axle at a position close to the axle end part. A plurality of positioning concave parts are arrayed in a circle on the outer wheel surface. A swing type wheel locking component is pivoted on the wheel axle and has a pivoting end and a swing section. The pivoting end is pivoted on the pivoting part, so that the swing section can be forced to swing, and by choosing different swing angles, it can be shifted between a locked position and released position. When a clamping convex part of the swing section is at a locked position, it is locked right inside the corresponding positioning concave part. Thus, the wheel body is locked against rotation.
