Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the conventional lock core structure with pin, restriction hole, and through hole is used, then the locking functionality is reliable, but the manufacturing complexity and production cost increase
Solution Approach 1:
The patent merges the pin, restriction hole, and through hole into a single integrated restriction unit. The restriction unit includes a body with a passage that has a first opening, second opening, and an extension wall, eliminating the need for separate pin and through hole components while maintaining the same functional constraints on lock core movement.
Solution Approach 2:
The restriction unit serves multiple functions simultaneously: it restricts the axial movement of the lock core, guides the movement path, and provides structural support. The passage and extension wall together perform the functions previously distributed across multiple separate components.
2Stability of the object's composition
If the conventional lock core structure with multiple components is used, then the locking mechanism is stable, but the assembly time and production cost increase
Solution Approach 1:
By combining multiple components into the integrated restriction unit, the number of assembly steps is reduced. The restriction unit is installed as a single component rather than requiring separate assembly of pin, restriction hole, and through hole, directly reducing assembly time while maintaining structural stability.
3Manufacturing precision
If the conventional lock core structure with pin and restriction hole is used, then the axial displacement control is effective, but the manufacturing techniques and procedures become complex
Solution Approach 1:
The restriction unit integrates the displacement control features into a single manufacturable component. The passage and extension wall are formed as integral parts of the restriction unit body, allowing for simpler manufacturing processes compared to assembling multiple precision components like separate pins and restriction holes.
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 simplified lock core structure reduces production costs and assembly time while maintaining effective locking functionality, as the lock core's axial movement and elastic deformation facilitate secure engagement and disengagement of the latch unit with the lock hole.
Implementation Method 1
an elastic unit disposed between the end face and the extension wall, wherein deformation of the elastic unit is linked to axial movement of the lock core

AI summary
A lock includes a movable unit and a lock core structure including a restriction unit and a lock core. The restriction unit has a passage penetrating therethrough to form a first opening and a second opening on two opposite sides of the restriction unit. An extension wall is formed in the passage to face the second opening. The lock core is disposed in the passage to couple with the restriction unit and is selectively movable relative to the restriction unit in an axial direction. The lock core has an end face facing the extension wall and an extension portion disposed on one side of the lock core close to the first opening and selectively protruding outside the first opening. The movable unit selectively contacts the lock core and is able to reciprocally rotate, wherein rotation of the movable unit is linked to axial movement of the lock core.
