Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional anti-theft chains for laptops are cumbersome to use and store due to complex entangling processes and large sizes, making them inconvenient for everyday protection and portability.
Innovation Solution
A connection lock with a simple structure comprising a shell body, driving assembly, lock device, actuating member, and engaging assembly, which allows for easy operation by moving between unlocked and locked positions, engaging with anti-theft holes to prevent theft, featuring elastic members and a key-operated mechanism for unlocking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional anti-theft chain with key hole is used, then the laptop can be secured, but the size is larger and inconvenient to store or carry
Solution Approach 1:
The conventional anti-theft chain is segmented into two separate components: a compact lock body and a flexible chain. The lock body contains all locking mechanisms and can be detached, allowing the chain to be stored separately or coiled compactly when not in use, significantly reducing the volume occupied during portability.
Solution Approach 2:
The chain is designed with flexible links that can collapse into a compact coil configuration, transitioning from an extended linear form to a compact three-dimensional coil. This dimensional transformation allows the chain to occupy minimal space when stored, while maintaining full length and functionality when deployed.
2Reliability
If a conventional anti-theft chain with key hole is used, then the laptop can be secured, but the entangling process is complex
Solution Approach 1:
The lock body is equipped with an automatic locking mechanism that engages the chain with the laptop's anti-theft hole without requiring complex manual manipulation. When the chain is inserted into the hole and the lock is activated, the locking members automatically secure the chain in place, eliminating the need for complex entangling steps.
Solution Approach 2:
The lock body is pre-configured with locking members and spring mechanisms that are ready to engage immediately upon insertion. The spring-loaded components are pre-tensioned to automatically clamp onto the anti-theft hole edge, eliminating the need for users to perform complex manual assembly or entangling operations during use.
3Reliability
If a lock member with tendency to move toward locked position is used, then the locking reliability is improved, but the device complexity increases
Solution Approach 1:
The lock member is designed with inherent spring bias that automatically drives it toward the locked position without requiring additional actuators or complex control mechanisms. The spring-loaded design provides self-actuating locking action, maintaining high reliability while minimizing structural complexity through the use of simple elastic elements.

Function Achieved in This Case
The connection lock effectively prevents theft with a straightforward operation, reducing assembly and disassembly time, making it more appealing to consumers and easier to carry, while ensuring secure attachment to objects like laptops.
Implementation Method 1
a first elastic member disposed in the shell body and abutting against one of the actuating member and the driving assembly to bias the driving assembly in a direction toward the first position

AI summary
A connection lock is provided. A driving assembly is disposed to a shell body, is movable to be in first or second positions and further has a restricting portion. A lock device is disposed to the shell body and includes a lock member which is movable relative to the shell body to be in unlocked or locked positions and has a tendency to move toward the locked position. An actuating member is slidably disposed in the shell body. A first elastic member is disposed in the shell body and abuts against one of the actuating member and the driving assembly to bias the driving assembly in a direction toward the first position. A engaging assembly is disposed in the shell body and is movable to be in released or engaged positions and is configured to be inserted into an anti-theft hole of an object.
