Cover Member Fixing Part for Display Connector Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices, such as LCDs, face issues during assembly where cables connected to the PCB can be separated, leading to defective devices, and electromagnetic interference (EMI) from the connector causes malfunctions.
Innovation Solution
A display device design featuring a cover member with a fixing part that elastically presses the connector to the PCB, including a protrusion and contact part, and optionally a gasket or elastic member to prevent separation and suppress EMI, combined with a fastening system using screws and guide parts for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the connector is exposed through an opening in the cover member, then the cable connection is accessible for assembly, but the connector becomes vulnerable to separation and EMI interference
Solution Approach 1:
The cover member features a localized fixing part with an elastic pressing structure that applies focused pressure to the connector in the opening region. This creates a localized securement effect without requiring the entire cover member to be complex, maintaining ease of assembly while improving connector stability at the critical exposure point.
Solution Approach 2:
The fixing part with elastic pressing structure is pre-configured in the cover member to automatically secure the connector when the cover is assembled. This preliminary preparation of the fixing mechanism ensures the connector is secured before any potential separation can occur during subsequent handling or operation.
2Ease of operation
If the connector is exposed through an opening in the cover member, then the cable connection is accessible for assembly, but EMI generated from the connector causes malfunctions
Solution Approach 1:
The cover member incorporates a fixing part with elastic pressing structure at the specific location of the connector opening. This localized structural feature serves dual purposes: mechanically securing the connector and providing EMI shielding at the precise point where the connector is exposed, without requiring complete enclosure of the entire PCB.
3Reliability
If a fixing part with elastic pressing structure is added to the cover member, then the connector is secured to the PCB, but the device complexity increases
Solution Approach 1:
The fixing part is integrated directly into the cover member structure, merging the functions of the cover (protection and EMI shielding) with the fixing mechanism (connector securement). This consolidation eliminates the need for separate fixing components, reducing overall device complexity while maintaining connector stability.
Solution Approach 2:
The elastic pressing structure in the fixing part utilizes its own material elasticity to automatically secure the connector. The elastic deformation and recovery of the fixing part provides the securing force without requiring additional actuators, springs, or complex mechanical mechanisms, thereby simplifying the overall structure while ensuring reliable connector fixation.
