Flat Panel Display Segmented Rear Cover Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flat panel displays face challenges in reducing weight and volume while maintaining functionality, as certain materials with specific functions are difficult to eliminate, leading to bottlenecks in design and manufacturing.
Innovation Solution
The design separates the display module and printed circuit board into distinct regions within the rear and front covers, using a supporter to fasten the printed circuit board on the back plate and locking other boards on the rear cover, allowing for non-overlapping configurations that reduce thickness and volume, while also simplifying manufacturing and reducing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If the back plate is reduced to lose weight by canceling hook slips or lock holes, then weight is reduced, but there is no place for fixing the system boards
Solution Approach 1:
The invention divides the back plate into two functional regions: a panel region for supporting the display module and a printed circuit board region for fixing system boards. This segmentation allows the back plate to maintain both weight reduction and fixing capability by allocating different areas for different functions, eliminating the need for traditional hook slips or lock holes while providing dedicated space for circuit board mounting.
2Volume of moving object
If the display module and printed circuit board are disposed at different regions, then thickness and volume are reduced, but the structure becomes more complex
Solution Approach 1:
The back plate is segmented into distinct panel region and printed circuit board region, creating a clear spatial separation between the display module and circuit boards. This segmentation simplifies the overall structure by providing predefined mounting areas, making assembly straightforward despite the functional separation that reduces volume.
Solution Approach 2:
The invention utilizes the planar dimension of the back plate to separate components horizontally rather than stacking them vertically. By disposing the display module and printed circuit board in different regions of the same plane, the design reduces the thickness dimension while maintaining a relatively simple single-plane structure, avoiding complex three-dimensional stacking arrangements.
3Adaptability or versatility
If multiple printed circuit boards are locked on the back plate, then functionality is improved, but manufacturing cost and complexity increase
Solution Approach 1:
The invention merges multiple printed circuit boards into a single integrated circuit board region on the back plate. Instead of providing separate mounting structures for each board, the design consolidates them in a dedicated area, allowing multiple boards to be arranged and fixed in a standardized manner. This merging approach maintains the functionality of supporting multiple boards while simplifying manufacturing processes and reducing costs.
