PCB Supporter System for Display Apparatus Vibration Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Miniaturization and slimming of electronic devices lead to increased vulnerability of electronic components on printed circuit boards (PCBs) to external vibrations and impacts, causing damage and electrical shorts, and existing PCB supporters either require manual insertion or are costly.
Innovation Solution
A display apparatus with a supporter system that includes a clinch head and a second body with a bent portion and extension, inserted through a via hole in the PCB, which is auto-inserted and soldered to prevent component interference with the chassis and fix leads, while also reducing manufacturing costs by using an existing eyelet component.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a manual insert supporter is used, then the PCB is protected from damage, but productivity deteriorates due to manual insertion and bonding tasks
Solution Approach 1:
The supporter head is designed to be automatically inserted and fixed into the PCB through self-clinching action, eliminating the need for manual insertion and bonding operations. The clinching structure allows the supporter to secure itself to the PCB automatically during the insertion process, thereby improving productivity while maintaining protection functionality.
2Volume of moving object
If an electronic component is mounted close to the chassis, then device miniaturization is achieved, but the component becomes vulnerable to external vibrations and impacts
Solution Approach 1:
The supporter structure is installed beforehand to provide protective cushioning to electronic components before they are exposed to external vibrations and impacts. The supporter extends from the PCB toward the chassis, creating a protective barrier that absorbs and mitigates the effects of external forces, thereby protecting closely-mounted components while maintaining device miniaturization.
3Length of stationary object
If the PCB is pressed by the chassis, then device slimming is achieved, but electrical shorts or PCB bending may occur
Solution Approach 1:
The supporter acts as an intermediary structure between the PCB and the chassis. It provides mechanical support and spacing that prevents direct pressing of the PCB against the chassis, thereby avoiding electrical shorts and PCB bending while still enabling device slimming. The supporter mediates the interaction between these two components to maintain both thickness reduction and electrical safety.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The supporter system effectively protects electronic components from damage, reduces the risk of electrical shorts, and improves manufacturing productivity by automating the insertion process and reducing costs compared to surface-mounted device supporters.
Implementation Method 1
The head of the supporter may be clinched in an auto insert process.
Implementation Method 2
The lead may be located inside the supporter, and the lead may be fixed in the supporter by soldering.
Implementation Method 3
The head may be soldered on the second surface, the second body may be soldered on the first surface, and a via hole may be provided inside the supporter.
