Lock Support Structure for Transmission Element Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional locks experience instability and misalignment issues due to gaps at the lock core connection, leading to easy shaking and improper external forces causing the transversally slidable element to separate from the handle, compromising security.
Innovation Solution
A lock design featuring a support structure within the tubular element, including a ring with a center hole and external circular surface, which supports the transmission element when in a locked state, limiting movement of the transversally slidable element through engagement with both the transmission element and the ring's support portion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the transmission element is connected to the lock core without additional support, then the device complexity is reduced, but the stability and reliability of the transmission element deteriorates due to gaps causing easy shaking
Solution Approach 1:
A support structure (ring) is introduced as an intermediary component between the transmission element and the tubular element. This ring provides additional support and reduces gaps, preventing the transmission element from shaking excessively while maintaining a relatively simple overall structure.
Solution Approach 2:
The support structure is designed as a separate ring component that can be independently manufactured and assembled. This segmentation allows for precise manufacturing of each component and facilitates assembly, while the ring itself provides the necessary support function without complicating the overall design.
2Ease of operation
If the transversally slidable element is allowed to move freely without support, then the ease of operation is improved for handle removal, but the reliability deteriorates as improper external force causes separation from the positioning hole
Solution Approach 1:
The support structure (ring) acts as a mediator between the transversally slidable element and the tubular element. It provides guidance and support to the slidable element, preventing excessive movement and separation from the positioning hole, while still allowing controlled movement for legitimate handle removal operations.
Solution Approach 2:
The support structure is pre-installed in the tubular element to provide protective support before any external forces are applied. This beforehand support prevents the transversally slidable element from being pushed out of position by improper external forces, while still allowing normal operation.
3Manufacturing precision
If gaps are present at the lock core connection position, then the manufacturing precision requirements are reduced, but the stability deteriorates leading to easy shaking of the transmission element
Solution Approach 1:
The ring support structure serves as a mediator that compensates for gaps and misalignments between the lock core and transmission element. It provides a stable support surface that reduces the impact of manufacturing tolerances and prevents excessive shaking, allowing for reasonable assembly tolerances without compromising stability.

Function Achieved in This Case
Enhances security by ensuring the transversally slidable element remains engaged with the handle, preventing unauthorized removal and maintaining stability under external forces, thus improving the lock's operational reliability.

AI summary
A lock with a support structure includes a tubular element connected to a handle having a positioning hole and a center hole. The center hole contains a lock set having a rotatable lock core connected to a transmission element. The transmission element has separated first and second sides. A transversally slidable element is installed to the tubular element for receiving a bias pressure of an elastic element, and includes a protruding portion and a bearing portion. The protruding portion can be moved between engaged and non-engaged positions of the positioning hole of the handle. The support structure includes a support portion. If the first side of the transmission element approaches the support portion of the support structure, the bearing portion of the transversally slidable element will approach the second side of the transmission element for limiting the displacement of the transversally slidable element when an external force is applied.
