Adjustable Push-Pull Lock Mounting for Variable Door Thickness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing push-pull passage locks have a fixed distance between mounting plates, making them incompatible with doors of varying thicknesses, leading to resource wastage and inconvenience in selecting lock cylinders.
Innovation Solution
An adjustable push-pull passage lock mounting device with a handle assembly featuring a first and second mounting plate, an adjusting ring or insert, and a central actuator block, allowing the distance between the plates to be adjusted using threaded studs and inserts, enabling adaptation to different door thicknesses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the distance between mounting plates is fixed, then the structure is simple and easy to manufacture, but the lock cannot adapt to doors of various thicknesses
Solution Approach 1:
The mounting plate distance is made adjustable rather than fixed. Threaded studs with adjusting rings allow the distance between mounting plates to be dynamically changed according to door thickness, transforming a static structure into a dynamic one that can adapt to different conditions.
Solution Approach 2:
The physical parameter of distance between mounting plates is made variable. By changing the position of threaded studs and adjusting rings, the distance parameter can be modified to match different door thicknesses, enabling the lock to adapt to various door sizes.
2Ease of manufacture
If the distance between mounting plates is fixed, then manufacturing is simple, but various manufacturing molds are needed for different door thicknesses, wasting resources and labor
Solution Approach 1:
A single lock body design with adjustable mounting plates can serve multiple door thickness requirements. The threaded studs and adjusting rings mechanism allows one universal lock design to accommodate various door sizes, eliminating the need for multiple specialized molds and reducing manufacturing complexity.
3Adaptability or versatility
If the distance between mounting plates is adjustable, then the lock can adapt to various door thicknesses, but the adjustment mechanism increases device complexity
Solution Approach 1:
The adjustment mechanism is divided into separate modular components: threaded studs, adjusting rings, and mounting plates. This segmentation allows each component to perform a specific function and facilitates easy assembly and disassembly, reducing the perceived complexity while maintaining adjustability.
Solution Approach 2:
Threaded studs act as intermediary elements between the adjusting rings and mounting plates. These intermediaries provide a standardized interface that simplifies the adjustment process and reduces the complexity of direct connections, allowing for easy modification of mounting plate positions.
