Bicycle Pedal Locking Hook Unit Assembly and Mud Clearance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bicycle pedals are difficult to assemble, prone to mud obstruction between the locking hook unit and spindle, and require complex assembly processes, leading to user inconvenience and increased fabrication costs.
Innovation Solution
A pedal design featuring a detachable locking hook unit with a fixing hook and movable hook having elastic torque, secured by locking bolts, allowing easy assembly and disassembly, and a hollow interior to prevent mud obstruction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional locking hook unit is mounted on the pedal body, then the pedal can attach the shoe, but the assembly process becomes difficult and time-consuming
Solution Approach 1:
The locking hook unit is divided into separate components (locking hook, fixing hook, elastic element) that can be independently assembled. The locking hook can be attached to the shoe separately and then connected to the pedal body, simplifying the overall assembly process while maintaining secure attachment.
Solution Approach 2:
The locking hook unit incorporates movable and fixed hooks with elastic torque, allowing dynamic adjustment during assembly. The elastic element enables the locking mechanism to flex and snap into place, making assembly easier while ensuring reliable shoe attachment.
2Reliability
If a conventional locking hook unit is used, then the pedal structure is complete, but mud easily accumulates between the locking hook unit and spindle causing inconvenience
Solution Approach 1:
The design extracts or removes the problematic area where mud accumulates by creating clearance between the locking hook unit and the spindle. The locking hook unit is positioned and structured to prevent mud from being trapped in the interface between these components, eliminating the harmful effect of mud obstruction.
3Reliability
If a complex locking hook unit assembly is used, then the pedal can function properly, but the fabrication cost increases
Solution Approach 1:
By segmenting the locking hook unit into separate, simpler components that can be manufactured independently and assembled, the fabrication process becomes more efficient. Each component can be produced using standard manufacturing processes, reducing overall fabrication costs while maintaining proper pedal functionality.
Solution Approach 2:
The locking hook unit is designed with universal features that allow it to perform multiple functions (attaching shoe, providing locking mechanism, allowing easy assembly) using a simple structure. This multi-functionality reduces the need for additional complex components, thereby lowering fabrication costs.

AI summary
A pedal for a bicycle includes pedal body, and at least one locking hook unit detachably mounted on the pedal body. The locking hook unit includes a fixing hook and a movable hook. Thus, the locking hook unit is locked onto the pedal body by a plurality of locking bolts to assemble the pedal, so that the pedal is assembled and disassembled easily and quickly, thereby facilitating a user assembling and disassembling the pedal. In addition, the locking hook unit has a hollow inside so that after the locking hook unit is attached to the pedal body, the spindle of the pedal body will not be obstructed by the locking hook unit to prevent the mud from being choked between the locking hook unit and the spindle of the pedal body.
