Bistable Bicycle Lock Mount With Auto-Locking Pivot Clamps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing two-wheeler holders for accessories, particularly locks, are not compact, easy to use, and fail to securely hold items without requiring manual locking or unlocking, posing safety risks due to potential accidental release or falling during driving.
Innovation Solution
A holder with pivoting brackets and a spring device that automatically transitions between release and securing positions, allowing easy insertion and removal of accessories without manual operation, ensuring secure retention through a bistable system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a bracket is used to attach locks to a bicycle, then the lock is securely held, but the lock cannot be easily removed without a key
Solution Approach 1:
The clamp is designed to be movable between a locked position and an unlocked position. The spring device enables automatic transition between these states, making the holder dynamic rather than static. This allows easy removal of the lock by simply placing it on the holder, which automatically transitions to the locked state.
Solution Approach 2:
The holder performs the locking action automatically through the spring device and dead center mechanism without requiring manual intervention or a key. When the lock is placed on the holder, the spring force automatically drives the clamp into the locked position, making the system self-servicing.
2Ease of operation
If a folding lock is attached to the bicycle, then it can be stored conveniently, but the bars may unfold uncontrollably posing a safety danger
Solution Approach 1:
The clamp exerts a pre-tensioning force on the folding lock bars, holding them in a fixed folded state. This preliminary constraining action prevents the bars from unfolding uncontrollably during storage on the bicycle, eliminating the safety hazard while maintaining convenience.
3Volume of moving object
If the holder is designed to be compact, then it does not impede rider safety, but it may have limited space for accessories
Solution Approach 1:
The holder is designed with a universal clamp mechanism that can accommodate various types of accessories, not just locks. The adjustable and multi-position clamp can secure different sizes and shapes of items, providing versatile functionality within a compact form factor.
4Reliability
If manual locking and unlocking mechanisms are used, then secure retention is achieved, but the operation becomes complex and time-consuming
Solution Approach 1:
The complex manual locking and unlocking mechanisms (such as keys, locks, or multiple fasteners) are removed from the system. Instead, a simple spring-driven automatic clamping mechanism is used that secures the accessory reliably without requiring any manual locking operations.
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 holder provides a compact, user-friendly solution that securely holds two-wheeler accessories, preventing accidental release and enhancing safety by automatically adjusting to secure or release positions based on accessory placement, thus ensuring reliable storage and operation.
Implementation Method 1
a spring device is provided which acts on the respective lever leg and is designed to preload the respective pivot clamp into the release position on one side of the dead center and into the locking position on the other side of the dead center
Implementation Method 2
one or more pivoting clamps which each comprise a holding leg and a lever leg and which can be pivoted about a pivot axis between a release position and a securing position beyond a dead center

AI summary
A bracket for a two-wheeled accessory, in particular for a two-wheeled lock, comprises a base body that defines a contact surface against which the two-wheeled accessory rests when it is received in the bracket, and one or more pivoting clamps, each comprising a retaining leg and a lever leg, and pivotable about a pivot axis across a dead center between a release position and a locking position, in order to allow the two-wheeled accessory to be received into or removed from the bracket in the release position and to lock the two-wheeled accessory, when it is received in the bracket, against removal from the bracket by means of the retaining leg in the locking position.A spring device is provided that acts on the respective lever leg and is designed to pre-tension the respective pivot clamp into the release position on one side of the dead center and into the locking position on the other side of the dead center.
