Reusable Bicycle Mudguard Stay Release Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for simplified release of bicycle mudguard stays are either irreversible, expensive, or impractical for reuse after a safety intervention, often detaching from the frame and losing functionality, which compromises cyclist safety.
Innovation Solution
A device composed of two half-shells solidly fixed to the bicycle frame with connecting devices that allow elastic deformation to release the mudguard stays without breaking, remaining attached to the frame and allowing easy reconnection, ensuring safety and practicality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If irreversible release devices are used, then safety intervention is achieved, but the device breaks and becomes unusable after intervention
Solution Approach 1:
The device is designed to be reusable rather than disposable. The housing and release mechanism are constructed to withstand multiple cycles of engagement and disengagement, allowing the device to be recovered and reused after safety intervention without breaking or requiring replacement.
Solution Approach 2:
The release mechanism employs dynamic characteristics including elastic deformation of the housing and spring-loaded release elements that allow reversible operation. The housing can elastically deform during normal operation and return to its original state, enabling repeated use while maintaining safety functionality.
2Reliability
If multi-part release devices are used, then safety intervention is achieved, but the device becomes complex and expensive to install
Solution Approach 1:
The device merges multiple functional components into an integrated housing structure. The housing combines the retention function, release mechanism, and mounting interface into a single unified component, reducing the number of separate parts while maintaining safety intervention capabilities.
Solution Approach 2:
The housing serves multiple functions simultaneously: it retains the stay during normal operation, provides the release mechanism when needed, offers mounting interfaces for attachment to the bicycle frame, and protects the internal components. This multi-functionality reduces overall device complexity.
3Reliability
If devices detach from the frame after intervention, then stay release is achieved, but the device falls to the ground and is lost
Solution Approach 1:
The device is segmented into two independent functional systems: a permanent mounting system that remains attached to the bicycle frame, and a temporary retention system that releases the stay. The housing maintains its mounting attachment to the frame while allowing the stay to be released, preventing loss of the device itself.
Solution Approach 2:
The housing acts as an intermediary between the permanent frame mounting and the temporary stay retention. It provides a stable connection to the frame while containing the release mechanism, ensuring that the device remains attached to the bicycle after intervention and does not fall to the ground.
4Reliability
If devices require special tools for resetting, then safety conditions are restored, but the process becomes complex and time-consuming
Solution Approach 1:
The device is designed to be self-resetting through user-friendly manual operation. The housing and release mechanism are configured to allow the cyclist to easily re-engage the stay by simple manual actions without requiring special tools, technical expertise, or complex procedures, thereby restoring safety conditions independently.
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
The device provides a cost-effective, reusable, and easy-to-install solution that maintains safety conditions by allowing the mudguard stays to be released and reconnected without tools, ensuring the device remains functional and attached to the frame post-intervention.

AI summary
The device for the simplified release of the mudguard stays, which are the object of the invention, allows the stays held by the device to be released without any damage to the device itself, which can therefore be re-used to retain the stays once again.
