Double-Sided Nylon Lock Linkage for Press-and-Pull Door Opening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional locksets are often complex, prone to faults, and require inconvenient single-sided unlocking operations, which can be cumbersome and inefficient, especially in scenarios where access is needed from both sides of the door.
Innovation Solution
A simplified double-sided nylon lock design featuring a first lock body for pressing and a second lock body for pulling, connected by a linkage, allowing synchronized unlocking and opening from either side, with a simplified transmission structure and safety mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional locksets use single-sided unlocking mechanism, then the structure can be simpler, but the ease of operation deteriorates because users must go around to the other side of the door to unlock
Solution Approach 1:
The lock body is divided into two separate lock bodies (first lock body and second lock body) mounted on opposite sides of the door. Each lock body has its own cylinder plug seat and transmission components, allowing independent unlocking operations from either side while maintaining simplified individual structures.
Solution Approach 2:
The linkage mechanism merges the transmission systems of both lock bodies into a unified structure that penetrates the door. When one lock body is unlocked, the linkage automatically triggers the other lock body to unlock simultaneously, combining two unlocking functions into one coordinated system.
2Reliability
If traditional locksets use complex transmission structure, then the reliability may be improved, but the device complexity increases and manufacturing cost rises
Solution Approach 1:
The patent extracts and eliminates unnecessary intermediate transmission components from traditional lock mechanisms. The transmission rod directly connects the cylinder plug seat to the lock tongue, removing redundant gears, cam mechanisms, or linkage arms that would increase complexity while maintaining reliable force transmission.
Solution Approach 2:
Instead of using a complex multi-stage transmission mechanism to amplify force, the patent inverts the approach by using the direct pulling force from the cylinder plug to actuate the lock tongue through a simple linear transmission rod, achieving reliable unlocking with minimal components.
3Adaptability or versatility
If traditional locksets lack double-sided unlocking capability, then the device complexity remains low, but the adaptability deteriorates in scenarios requiring access from both sides
Solution Approach 1:
The lock system achieves multi-functionality by enabling both lock bodies to serve as primary unlocking interfaces. Either the first lock body or the second lock body can be used to unlock the door, making the system adaptable to various usage scenarios including emergency access, shared facilities, and bidirectional entry points without requiring additional specialized mechanisms.

AI summary
Disclosed in the invention is a simplified double-sided nylon lock. A double-sided lock body includes a first lock body, which is mounted on a side of a door and is unlocked by pressing to open the door, a second lock body, which is mounted on the other side of the door and is unlocked by pulling-out to open the door, and a linkage, which penetrates the door, with one end thereof being connected to the first lock body and the other end thereof being connected to the second lock body. By virtue of the invention, a first lock body and a second lock body are provided, so as to implement different unlocking and door opening methods on two sides of a door.
