Detachable Pedal Platform with Inverted Strap Fastener
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing clipless pedals face challenges in accommodating different types of riding shoes with varying cleats, and conventional toe clips are difficult to adjust mid-ride due to design limitations, including the need for tools and accessibility issues during pedaling.
Innovation Solution
A dual-sided clipless pedal with a detachable platform and adjustable toe clip, featuring a spring-loaded claw and torsion spring mechanism for secure attachment and easy release, along with a strap fastener assembly that allows for upward force to pivot the lever and release the strap for adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional toe clip with ratchet system is used, then the strap can be tightened to secure the shoe, but the free end of the strap becomes inaccessible for adjustments during active pedaling
Solution Approach 1:
The free end of the strap is routed upward through the housing to an accessible location above the toe clip, inverting the conventional downward routing. This allows riders to easily access and adjust the strap during pedaling without the end becoming inaccessible or detaching from the ratchet system.
2Reliability
If a locking structure is added to prevent platform dislodgement, then the platform remains securely attached, but a unique tool is required to engage the lock
Solution Approach 1:
The platform incorporates a self-retaining mechanism with protrusions that automatically engage with recesses in the pedal body when the platform is positioned correctly. The spring-loaded clip maintains continuous pressure to keep the platform securely attached, eliminating the need for external tools while ensuring reliable retention.
3Ease of operation
If a spring-loaded clip mechanism is used to secure the platform, then easy release is enabled, but the clip may inadvertently disengage under substantial force
Solution Approach 1:
The design merges a spring-loaded clip mechanism for easy release with a multi-point locking system featuring protrusions that engage with recesses. The spring maintains pressure on the locking features, providing both secure retention during normal use and convenient tool-free release when needed.
4Adaptability or versatility
If a dual-sided clipless pedal is used to accommodate different cleat types, then versatility is improved, but the platform may inadvertently dislodge from the interface
Solution Approach 1:
The pedal body incorporates multiple clipless interfaces on opposite sides to accommodate different cleat types (Look, SPD, etc.), providing universal compatibility. A detachable platform with spring-loaded clip and locking features secures the shoe to the pedal, preventing inadvertent dislodgement while maintaining versatility across different cycling disciplines.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables secure attachment and easy release of the platform, accommodating different shoe types and allowing for on-the-fly adjustments without tools, enhancing usability and compatibility across various cycling environments.
Implementation Method 1
The adjustable portion may be operable to receive an upward force to move the adjustable portion upward and pivot the lever against the bias force, thereby releasing the strap.
Implementation Method 2
The claw may be spring-loaded.

AI summary
A pedal that includes a pedal body having a clipless structure and a member. The clipless structure includes a lip at a first portion of the pedal and a cleat at a second portion of the pedal. The pedal includes a detachable shoe platform having a cleat portion securable to the lip and a clip securable to the member. The detachable shoe platform may include an adjustable toe clip having a strap, which wraps around a shoe of a rider. The strap is adjustable by an adjustable strap fastener assembly having a lever coupled to a plate secured in a housing. The lever includes a first end biased against the strap and a second end engaged by a trigger. The trigger is operable to move the lever from a closed position to an open position against the bias force, thereby releasing the strap for adjustment.
