Attraction Plate Arch Design for Electromagnetic Door Lock Tensile Strength
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing manufacturing methods for attraction plates in electromagnetic door locks do not consistently achieve optimal tensile values across different plate thicknesses, leading to suboptimal performance and safety concerns.
Innovation Solution
A manufacturing method involving an attraction plate with a thickness between 10-16 mm and a central arch portion height of 0.04-0.27 mm, featuring two convex-curve surfaces extending to both ends, which is inversely proportional to the plate thickness, to enhance tensile strength and energy efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the attraction plate thickness is increased, then the structural strength is improved, but the tensile value decreases
Solution Approach 1:
The patent applies curvature by forming an arch portion with convex-curve surfaces on the attraction plate. The arch portion has a height of 0.04-0.27 mm and extends along the central region, creating a curved structure that optimizes the distribution of mechanical stress. This curvature enables the plate to achieve both sufficient structural strength and optimal tensile values by distributing loads more effectively across the plate structure.
Solution Approach 2:
The patent changes the geometric parameters of the attraction plate by introducing the arch portion with specific height (0.04-0.27 mm) and convex-curve surfaces. This parameter modification transforms the flat plate into an arched structure, which fundamentally alters the mechanical properties and stress distribution, thereby resolving the contradiction between structural strength and tensile value.
2Force
If the arch portion height is increased, then the tensile value is improved, but the manufacturing precision requirement increases
Solution Approach 1:
The patent defines a specific range for the arch portion height (0.04-0.27 mm) that balances tensile value improvement with manufacturing feasibility. By establishing this parameter range, the patent optimizes the trade-off between achieving high tensile values and maintaining reasonable manufacturing precision requirements.

AI summary
A manufacturing method of an attraction plate for electromagnetic door locks has an attraction plate positioned on a mounted body with a positioning hole at the center thereof. The attraction plate further has an arch portion at the center thereof which is reversely proportional to a thickness thereof and the thickness thereof is pre-determined for manufacturing a different height of the arch portion thereof for better effects. With an internal stress from the curved design, a tensile value of a door lock is increased for better operation of a door lock.
