PCB Contact and Support Structure for Screwless Fixation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge of fixing a printed circuit board (PCB) within a foldable electronic device to prevent vertical movement, which can cause poor contact and damage due to interference, while minimizing space usage and avoiding the need for screws.
Innovation Solution
An electronic device design that includes a housing with conductive and non-conductive portions, a first substrate, a second substrate with a contact member between the substrate and the conductive portion, and a support member to prevent vertical movement, allowing for secure fixation without screws.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a screw is used to fix the PCB, then the PCB is securely fixed and vertical movement is prevented, but the mounting area is reduced and space for arranging other electronic components is reduced
Solution Approach 1:
The patent replaces the traditional screw-based mechanical fixation system with a clamp structure that uses elastic deformation and friction to secure the PCB. The clamp member deforms elastically to clamp the PCB between its clamping surface and the support surface, eliminating the need for screws and mounting holes, thereby preserving mounting area while maintaining fixation reliability
Solution Approach 2:
The patent introduces a clamp member as an intermediary component between the PCB and the housing. This clamp member acts as a mediator that transfers and distributes the fixing force across the PCB surface through its clamping action, preventing vertical movement without requiring direct screw-fastening to the PCB, thus avoiding reduction of mounting area
2Length of moving object
If the electronic device is made small for easy carrying, then portability is improved, but the display screen size is restricted
Solution Approach 1:
The patent employs a flexible display panel that can dynamically change its configuration between folded and unfolded states. When folded, the device maintains a compact form factor for easy carrying; when unfolded, the display screen expands to provide a larger viewing area. The clamp member also provides dynamic fixation that accommodates the flexible nature of the display while preventing vertical movement
