Display Module Magnetic Positioning to Prevent Assembly Damage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display modules are prone to damage during assembly due to instantaneous magnetic attraction to the casing, which can cause bumps and structural integrity issues.
Innovation Solution
A display module design incorporating a support assembly with movable magnetic elements and drive elements that adjust the position of the magnetic elements relative to the support element, reducing the magnetic attraction force during assembly, thereby minimizing damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the magnetic element is fixed on the support element, then the display module can be securely mounted on the casing, but the display module is prone to damage during assembly due to instantaneous magnetic attraction
Solution Approach 1:
The magnetic element is made movable relative to the support element through a drive mechanism (motor, screw, spring). During assembly, the magnetic element can dynamically adjust its position: moving away from the casing to avoid instantaneous strong attraction and damage, then moving close to achieve secure mounting. This dynamic positioning resolves the contradiction between mounting security and assembly safety.
2Strength
If the magnetic attraction force is strong, then the display module is firmly fixed on the casing, but the display module suffers damage due to instantaneous attraction during assembly
Solution Approach 1:
Before the display module approaches the casing during assembly, the drive mechanism preliminarily positions the magnetic element at a safe distance from the casing. This preliminary positioning prevents the instantaneous strong magnetic attraction that would cause impact damage. After safe approach, the magnetic element is then positioned close to achieve the required fixing strength.
Solution Approach 2:
The spring element provides beforehand cushioning by being pre-compressed or pre-tensioned to store elastic potential energy. When the magnetic element needs to move, the spring absorbs or provides force gradually, cushioning against sudden impacts from strong magnetic attraction while still enabling firm fixing when needed.
3Reliability
If the magnetic element is positioned close to the casing, then secure mounting is achieved, but the display module is vulnerable to bumps and structural integrity issues during assembly
Solution Approach 1:
The system dynamically controls the distance between the magnetic element and the casing. During assembly, the magnetic element maintains an optimal distance that provides sufficient mounting stability through magnetic attraction while avoiding positions that would cause excessive stress or bumps to the display substrate, thereby preserving structural integrity.
