Spring-Loaded Cycle Locking Bolt Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cycle locking devices in public storage systems are prone to unauthorized removal and incorrect locking due to slow micromotor operation and poor positioning, leading to security vulnerabilities.
Innovation Solution
A locking device with a bolt mechanism that evolves through distinct positions for engagement, locking, and disengagement, utilizing a mechanical transmission and return member to ensure secure locking only when correctly positioned, and automatic disengagement upon authorization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a micromotor is used to move the locking protrusions, then the locking device can be compact and portable, but the locking speed becomes too slow (more than 0.5 seconds) allowing unauthorized removal
Solution Approach 1:
The patent replaces the micromotor-driven mechanical system with a spring-based mechanical system. The spring member is pre-loaded and automatically engages the locking protrusions with the storage terminal openings without requiring motor actuation, achieving instant locking while maintaining compact size.
Solution Approach 2:
The spring member is pre-loaded in a compressed state before engagement, storing elastic potential energy. When the locking device is inserted into the storage terminal, the spring automatically expands and drives the locking protrusions into the openings without requiring external power or control, achieving rapid locking action.
2Reliability
If the micromotor locking procedure is initiated, then the cycle should be locked, but incorrect positioning causes the protrusions to not engage properly leading to stalling and failed locking
Solution Approach 1:
The patent changes the engagement parameter from motor-controlled positional precision to spring-driven forceful engagement. The spring member applies sufficient force to drive the locking protrusions into the storage terminal openings regardless of minor positioning errors, eliminating stalling and ensuring reliable locking within a broader tolerance range.
Solution Approach 2:
The spring member acts as a cushioning element that absorbs positioning errors and misalignment. The pre-loaded spring provides a buffer zone that allows the locking device to engage reliably even when not perfectly positioned, preventing the stalling that occurs with rigid motor-controlled systems.
3Reliability
If the bolt is made movable between multiple positions for secure locking, then locking security is improved, but the device complexity increases
Solution Approach 1:
The patent segments the bolt into multiple locking protrusions that can independently engage with the storage terminal openings. Each protrusion can be in a retracted or engaged state, providing multiple locking positions and enhanced security while maintaining a relatively simple overall structure through modular design.
Solution Approach 2:
The patent makes the locking protrusions dynamically movable between retracted and engaged positions through the spring mechanism. This dynamic capability allows the system to transition between different locking states (engaged, disengaged, partially engaged) providing enhanced security while using a simple spring-return design rather than complex multi-component mechanisms.

Function Achieved in This Case
The solution provides instant and secure locking of cycles to storage terminals, preventing unauthorized removal and ensuring reliable operation even with incorrect user interactions, while allowing easy disengagement when authorized.

AI summary
According to the invention, the locking device comprises a bolt (26) and is configured to change between: an engagement configuration, in which the bolt (26) is movable between a retracted position and a first protruding position, the bolt (26) being returned into the first protruding position by a return member (34); a locking configuration, by actuation of a control member (60), and in which the bolt (26) is locked in a second protruding position; and a disengagement configuration, by actuation of the control member (60), in which the bolt (26) is movable between an intermediate position and the retracted position, and in which the return member (34) puts the locking device in the engagement configuration when the bolt (26) is brought into the retracted position.
