Clipless Bicycle Pedal Assembly With Modular Cleat Securing Members
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional clipless bicycle pedals are difficult to assemble, disassemble, and maintain due to the direct connection of the biasing mechanism to the pedal body, making them cumbersome for ordinary users.
Innovation Solution
A bicycle pedal design featuring a detachable first cleat securing member and a rotatable second cleat securing member connected by a shaft, with a biasing mechanism between them, allowing easy assembly, disassembly, and replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the biasing mechanism is directly connected to the pedal body, then the pedal provides stable cleat securing force, but it becomes difficult to assemble, disassemble, maintain or replace
Solution Approach 1:
The pedal is divided into separate functional modules: the pedal body, the cleat securing member, and the biasing mechanism. This segmentation allows each component to be independently assembled, disassembled, maintained, or replaced without affecting the entire system, while still providing stable cleat securing force through the biasing mechanism's continuous elastic action.
Solution Approach 2:
The biasing mechanism incorporates an elastic element that provides dynamic, adjustable securing force. The elastic member can be compressed and expanded to accommodate different cleat positions and securing requirements, maintaining reliable contact while allowing for easy adjustment and replacement of components.
2Volume of moving object
If the biasing mechanism is directly connected to the pedal body, then the structure is compact, but it increases device complexity for ordinary users
Solution Approach 1:
By separating the biasing mechanism from the pedal body into distinct modules, the design reduces assembly complexity for users. Each module can be independently handled and assembled, making the overall system easier to understand and maintain despite maintaining a compact form factor when assembled.
Solution Approach 2:
The cleat securing member acts as an intermediary component between the pedal body and the biasing mechanism. This intermediate element simplifies the connection interface, allowing users to assemble and disassemble the system by simply attaching or detaching the securing member without dealing with the internal biasing mechanism directly.
3Reliability
If the biasing mechanism is directly connected to the pedal body, then the pedal maintains stable operation, but it is not easy to maintain or replace for ordinary users
Solution Approach 1:
The modular design separates the biasing mechanism into an independent, easily accessible component. Users can maintain or replace the biasing mechanism by simply removing the cleat securing member, which provides direct access to the elastic element without disassembling the entire pedal structure, thus maintaining operational stability while improving maintainability.
Solution Approach 2:
The design enables ordinary users to perform basic maintenance and replacement tasks themselves. The biasing mechanism is configured to be easily accessible and replaceable through simple user actions, eliminating the need for specialized tools or expert intervention for routine maintenance.
