Adjustable Bicycle Pedal Sliding Axial Position
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bicycle clipless pedals have a fixed structure that cannot be easily adjusted to accommodate different foot sizes, shapes, and pedaling manners, leading to inefficiencies in pedaling and requiring complex and time-consuming adjustment processes.
Innovation Solution
An adjustable pedal design featuring a pedal body with clamp portions that can slide along a pedal shaft, allowing for quick and stepless adjustment of the distance between the pedal and crank, utilizing a movable engaging portion connected through screw structures or buckles for secure and easy positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional fixed-position pedal shaft is used, then the pedal structure is simple and robust, but the pedal cannot be adjusted to accommodate different foot sizes, shapes, and pedaling manners
Solution Approach 1:
The patent applies the dynamics principle by making the pedal body movable relative to the pedal shaft through a sliding mechanism. The pedal body can slide along the axial direction of the pedal shaft and be fixed at different positions using engaging portions, transforming a static fixed-position structure into a dynamic adjustable one. This allows the pedal to adapt to different foot sizes and pedaling preferences without requiring a complex multi-component adjustment system.
2Adaptability or versatility
If a complex adjustment structure is implemented to allow pedal position adjustment, then the pedal can accommodate different users, but the adjustment process becomes time-consuming and complicated
Solution Approach 1:
The patent applies segmentation by dividing the pedal assembly into distinct functional components: a pedal body, a pedal shaft, and engaging portions. The engaging portions can be independently positioned and fixed at different locations along the pedal shaft, allowing for quick adjustment without requiring complex disassembly or reconfiguration. This segmented design enables users to rapidly adjust the pedal position by simply moving and securing the engaging portions.
3Ease of operation
If the pedal body is fixed to the pedal shaft, then the structure is stable and robust, but the pedal cannot be quickly repositioned for different riding conditions
Solution Approach 1:
The patent implements dynamics by creating a movable yet stable connection between the pedal body and pedal shaft. The pedal body can slide along the axial direction of the pedal shaft during adjustment, and the engaging portions provide secure fixation at selected positions. This dynamic design maintains stability during pedaling while enabling easy repositioning when needed, resolving the contradiction between operational ease and structural stability.

AI summary
An adjusted pedal is provided, including: a pedal body, having two clamp portions respectively configured to engage with a shoe; a pedal shaft, defining an axial direction; an engaging portion, disposed on the pedal body and movably engaged with the pedal shaft so that the pedal body is slidable positionly to the pedal shaft along the axial direction; wherein when the engaging portion is disengaged with the pedal shaft, the pedal body is slidable to the pedal shaft along the axial direction.
