Rotatable Bicycle Lock Mounting with Adjustable Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lock holders for bicycles do not securely carry locks without rattling, fail to position them inconspicuously, and hinder cyclist movement while not facilitating easy release when needed.
Innovation Solution
A lock mounting arrangement with a rotatable mounting member and engagement mechanism that allows for adjustable positioning of the lock relative to the bicycle frame, enabling secure, tool-free adjustment and convenient release.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the lock is securely mounted on the bicycle frame, then the lock is held firmly without rattling, but the lock may hinder movement of the cyclist and be conspicuous
Solution Approach 1:
The mounting member is made rotatable relative to the lock body, allowing dynamic adjustment of the lock's position on the bicycle frame. This enables the lock to be positioned in optimal locations that balance security, visibility, and cyclist movement, while the engagement member maintains secure fixation when positioned correctly.
Solution Approach 2:
The engagement member can be positioned at different locations on the mounting member, changing the angular parameter of the lock's orientation. This allows the lock to be adjusted between various positions on the bicycle frame, optimizing it for different riding conditions and cyclist preferences while maintaining secure mounting.
2Stability of the object's composition
If the lock position is fixed on the bicycle frame, then the lock remains stable, but the lock cannot be easily adjusted or repositioned when needed
Solution Approach 1:
The mounting member incorporates rotational capability allowing it to be adjusted between fixed and movable states. When engaged, it provides stable fixation; when disengaged, it allows repositioning. This dynamic characteristic enables both stability during use and adaptability when adjustment is needed.
Solution Approach 2:
The mounting arrangement is divided into separable components: the lock body, the rotatable mounting member, and the engagement member. This segmentation allows the engagement member to be independently positioned and engaged at different locations, providing both stable fixation when engaged and adjustability when disengaged.
3Reliability
If the engagement member is always engaged to fix the mounting member position, then the lock is securely fixed, but the lock cannot be easily released or repositioned
Solution Approach 1:
The engagement member is designed to be easily disengaged and repositioned by the user without requiring tools or complex mechanisms. The simple engagement and disengagement action allows the user to quickly adjust or release the lock position as needed, while maintaining secure fixation when engaged.
Solution Approach 2:
The engagement member transitions between engaged and disengaged states, dynamically changing the locking mechanism from a fixed state to a movable state. This simple dynamic transition enables easy release and repositioning while maintaining reliable secure fixation when engaged, balancing both requirements.

AI summary
A bicycle lock (20) and a mounting member (26) secured to a portion (21) of the lock (20) such that the mounting member (26) is rotatable relative to the portion (21) of the lock. The mounting member (26) is provided with a tongue portion (52) for securing the lock (20) to the bracket (28) mounted on the bicycle. At least two position delineators (76) are provided on one of the mounting member (26) and the lock (20) and an engagement member (66) is provided on the other of the mounting member and the lock. The engagement member (66) is movable between a first position in which the engagement member (66) engages at least one of the position delineators (76) and thereby fixes the rotative position of the mounting member (26) relative to the portion of the lock (21) and a second position in which the engagement member (66) is lockingly disengaged from the position delineators (76) such that the mounting member (26) is free to rotate relative to the portion of the lock (21).
