Portable Lock Mounting Assembly Cam Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lock holders for bicycles and cable locks fail to securely carry the locks without rattling, position them inconspicuously, and facilitate easy release when needed.
Innovation Solution
A portable lock mounting assembly with a body, strap, and cam mechanism that provides adjustable tension to securely attach the lock to the bicycle frame, minimizing rattling and allowing convenient release.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a strap is used to attach the lock to the bicycle frame, then the lock can be securely carried, but the lock may rattle and not be positioned inconspicuously
Solution Approach 1:
The cam member changes the tension parameter of the strap by pivoting between positions, transforming the strap from a loose state that causes rattling to a taut state that secures the lock firmly against the contact surface, eliminating noise while maintaining secure attachment
2Reliability
If the lock is securely attached to the bicycle frame, then it is carried safely, but it may be difficult to release when needed
Solution Approach 1:
The cam member is designed to be dynamically adjustable between multiple positions, allowing the user to easily pivot it to release the lock when needed, while maintaining a secure locked position during transport. The dynamic positioning capability enables both secure attachment and convenient release
3Reliability
If the strap tension is increased to eliminate rattling, then the lock is secured firmly, but the strap may become too tight to release easily
Solution Approach 1:
The cam member provides dynamic tension adjustment, allowing the strap to be tightly secured during transport to eliminate rattling, then easily loosened by pivoting the cam member to a different position, enabling convenient release without excessive force
Solution Approach 2:
The cam member operates in periodic cycles between tensioned and relaxed states, allowing the user to alternately secure and release the lock by simple pivotal movements, making the release process easy even after firm attachment
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 assembly securely attaches locks to the bicycle frame without rattling, positions them inconspicuously, and allows for easy release, addressing the limitations of prior art holders.
Implementation Method 1
A cam member is supported by the body adjacent the contact surface and is pivotal between a first position wherein the cam member extends generally parallel to the contact surface and a second position wherein the cam member extends at an angle relative to the contact surface
