Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Folding locks are vulnerable to damage due to their simple structure, compromising their anti-theft effectiveness.
Innovation Solution
A folding lock design featuring a locking structure with a sleeve assembly comprising inner and outer sleeves, a locking sleeve, and a lock core that restricts movement to prevent damage, enhanced by a connecting assembly and protective outer casing, ensuring the lock remains difficult to manipulate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a simple structure is used for the folding lock, then portability and small size are improved, but the lock becomes easy to damage and loses anti-theft effect
Solution Approach 1:
The patent implements a nested sleeve structure where an inner sleeve is placed inside an outer sleeve, both having openings aligned along the insertion direction. This nested arrangement provides enhanced structural strength and protection against damage while maintaining a compact form factor, directly resolving the contradiction between small size and structural strength.
2Ease of manufacture
If a simple structure is used for the folding lock, then ease of manufacture is improved, but the lock becomes vulnerable to damage
Solution Approach 1:
The nested sleeve structure consists of straightforward cylindrical components that can be manufactured using conventional processes. The inner and outer sleeves are simple tubular structures with openings, making them easy to produce while providing enhanced reliability through their nested configuration that protects against damage and manipulation.
3Strength
If multiple sleeves are added to enhance structural strength, then damage resistance is improved, but device complexity increases
Solution Approach 1:
The nested sleeve structure adds only two cylindrical components (inner and outer sleeves) with simple geometric shapes. These components nest within each other along the insertion axis, providing structural strength without introducing complex mechanisms or assemblies. The simplicity of the nested cylindrical design minimizes the increase in device complexity while effectively enhancing damage resistance.

AI summary
A folding lock comprises a lock body having a locking structure within a sleeve assembly, a folding plate assembly, and a connecting assembly The locking structure comprises a locking sleeve connected to the rotational shaft of a lock core through a connecting piece. The folding plate assembly has a first movable plate with an insertion protrusion having a protruding lock block, a second movable plate, and a plurality of intermediate plates connected to each other, wherein the insertion protrusion inserts upward along the Y-axis into the lock body The locking sleeve restricts the movement of the lock block, and the sleeve assembly reinforces the structure which restricts the rotation of the locking sleeve, thereby increasing the overall structural strength to make the folding lock difficult to damage and achieve a better anti-theft effect.
