Multi-function Bicycle Pedal with Removable Shoe Clip
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Clipless bicycle pedals are not intuitive for beginners to unlock, posing safety risks, and they cannot be used with general shoes or toe clips, limiting their versatility and user compatibility.
Innovation Solution
A multi-function racing type bicycle pedal design that allows for optional attachment of a flat tread and shoe clip, enabling operation as a clipless, platform, or clipped pedal, with a pedal body featuring a spindle, fixed front, elastic rear, and a connecting seat with anti-slip pattern, accommodating both cleat engagement and general shoe use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If clipless pedals are used to improve transmission efficiency and foot fixation, then the rider can output driving power throughout the entire crank revolution, but unlocking becomes non-intuitive and requires practice, posing safety risks for beginners
Solution Approach 1:
The pedal system is segmented into modular components: a base pedal body, removable connecting seats, and interchangeable attachments (toe clips or flat treads). This segmentation allows the pedal to transform between different operational modes, providing both secure clipless engagement and intuitive toe clip-style release mechanisms.
Solution Approach 2:
The pedal system dynamically adapts its engagement mechanism based on the attached component. When a toe clip or flat tread is attached, the release becomes intuitive by pushing the toe forward. When used in pure clipless mode, the mechanical engagement provides secure fixation. The system's behavior changes based on configuration.
2Reliability
If clipless pedals are designed for exclusive cycling shoe compatibility, then secure engagement is achieved, but versatility is reduced as general shoes cannot be used
Solution Approach 1:
The pedal base is designed as a universal platform that can accommodate multiple types of attachments and shoe types. The connecting seat with standardized mounting holes accepts both toe clips and flat treads, enabling the same pedal to work with cycling shoes, general athletic shoes, or bare feet depending on the attached component.
Solution Approach 2:
The pedal system dynamically adapts its engagement mechanism based on the attached component. When a toe clip or flat tread is attached, the release becomes intuitive by pushing the toe forward. When used in pure clipless mode, the mechanical engagement provides secure fixation. The system's behavior changes based on configuration.
3Adaptability or versatility
If toe clips are added to clipless pedals to improve versatility, then general shoe compatibility is achieved, but the pedal structure becomes more complex
Solution Approach 1:
The pedal system is segmented into modular components: a base pedal body, removable connecting seats, and interchangeable attachments (toe clips or flat treads). This segmentation allows the pedal to transform between different operational modes, providing both secure clipless engagement and intuitive toe clip-style release mechanisms.
Solution Approach 2:
The connecting seat is pre-configured with mounting holes and attachment points that simplify the process of adding toe clips or flat treads. Users can quickly attach or remove these components without complex assembly procedures, reducing the perceived complexity despite the multi-functional capability.

AI summary
A multi-function racing type bicycle pedal includes a pedal body, a connecting seat and a shoe clip. The pedal body has a spindle, a fixed front and an elastic rear. An engaging surface is formed between the fixed front and the elastic rear for optionally connecting a cleat. A connecting platform is formed on an opposite side of the engaging surface and at a front side and a rear side of the spindle. The connecting platform has a locking hole. The connecting seat is a flat plate and has a through hole corresponding to the locking hole for being passed through by a screw so as to removably fasten the connecting seat onto the connecting platform. An exposed surface of the connecting seat is provided with an anti-slip pattern. The shoe clip is an arcuate body and removably disposed on the connecting seat.
