Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bicycle lock mounting brackets face issues with ease of use, reliability in securing the lock, and rattling during riding, necessitating improvements for secure and stable lock attachment.
Innovation Solution
A mounting bracket with a housing, movable arms, a pinion, a latch, and a manual actuator, allowing for secure locking and easy release of a bicycle lock, featuring a biasing mechanism to maintain the lock in a seated position and prevent rattling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional mounting brackets are used to secure a bicycle lock, then the lock can be mounted to the bicycle frame, but the lock rattles during riding and is not reliably secured
Solution Approach 1:
The mounting bracket employs movable arms that can dynamically adjust their position between extended and retracted states. The arms move from an extended position during mounting to a retracted position during riding, adapting the bracket's structure to different operational phases to eliminate rattling while maintaining secure attachment.
Solution Approach 2:
The bracket changes its geometric parameters by altering the position of the arms. When the arms are retracted against the bicycle frame, they change the spatial configuration of the mounting structure, creating a rigid assembly that prevents lock movement and rattling during bicycle operation.
2Reliability
If the arms are held in a fixed secured position, then the lock is reliably retained, but the bracket is difficult to operate for mounting and removal
Solution Approach 1:
The arms are pre-biased toward the retracted position through spring mechanisms, automatically preparing the bracket for secure retention once the lock is inserted. This preliminary positioning eliminates the need for manual adjustment during operation, maintaining reliability while simplifying the mounting process.
Solution Approach 2:
The bracket uses spring-loaded arms that automatically move into the retracted position to secure the lock without requiring additional user action. The system serves itself by using the insertion of the lock to trigger the arms' movement, thereby securing the lock reliably while keeping the operation simple and intuitive.
3Ease of operation
If the arms are extended outward for easy lock insertion, then the lock can be easily mounted, but the lock is not securely retained and may pivot
Solution Approach 1:
The arms dynamically transition from an extended state during insertion to a retracted state for retention. This dynamic movement allows the bracket to provide both easy access for mounting and secure retention during riding, resolving the contradiction between operational ease and security.
Solution Approach 2:
The spring mechanism pre-positions the arms in a state ready to secure the lock immediately upon insertion. The arms are biased to move inward automatically, providing beforehand the securing action needed to prevent lock pivoting and ensure reliable retention right from the start of the mounting process.

AI summary
An exemplary mounting bracket is configured for releasably securing a bicycle lock to a bicycle, and generally includes a housing, a pair of opposing arms, a pinion, a latch, and a manual actuator. The arms are movably mounted to the housing for movement between inward positions and outward positions, and each arm includes a rack gear. The pinion is engaged with each rack gear and correlates movement of the arms such that the arms move with one another between the outward positions and the inward positions. The latch has a latching position in which the latch is operable to maintain the arms in the inward position, and has an unlatching position in which the arms are free to move from the inward position to the outward position. The manual actuator is operable to move the latch between the latching position and the unlatching position.
