Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display apparatuses face issues with the control printed circuit board (C-PCB) becoming loose and moving during logistics transportation, leading to production delays and complicating the manufacturing process due to the need for fixing tape and separation of flexible printed circuits.
Innovation Solution
A display apparatus design featuring a holder member with a connecting part, bending part, and head part to securely hold the C-PCB, allowing stable fixation and simplifying the manufacturing process by eliminating the need for fixing tape and direct attachment to the set mid-frame.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If fixing tape is used to hold the control printed circuit board, then the C-PCB can be kept in place during assembly, but the C-PCB may become loose and move during logistics transportation
Solution Approach 1:
The holder member is divided into multiple functional segments: a connecting part that attaches to the S-PCB, a bending part that provides flexible connection, and a head part that directly holds the C-PCB. This segmentation allows each part to perform its specific function optimally, ensuring stable fixation during transportation while enabling easy assembly and disassembly during manufacturing.
2Stability of the object's composition
If fixing tape is used to hold the control printed circuit board, then the C-PCB can be positioned during assembly, but the manufacturing process becomes complicated due to separation requirements
Solution Approach 1:
The holder member merges multiple functions into a single integrated component: it combines the positioning function, the fixing function, and the electrical connection function (through the bending part connecting to FPC). This eliminates the need for separate fixing tape and simplifies the manufacturing process by allowing the C-PCB to be directly attached to the S-PCB assembly without complex separation and reconnection steps.
3Stability of the object's composition
If fixing tape is used to hold the control printed circuit board, then the C-PCB can be kept in place, but additional components and materials are required
Solution Approach 1:
The holder member is designed as a universal component that performs multiple functions simultaneously: it provides mechanical support and positioning for the C-PCB, ensures stable fixation during transportation, maintains electrical connections through the bending part, and enables easy assembly and disassembly. This multi-functionality eliminates the need for separate fixing tape, additional adhesives, and complex assembly tools, thereby reducing the total quantity of components and materials required.

AI summary
A display apparatus is disclosed that includes a display panel, a source printed circuit board placed on a back surface of the display panel and connected to the display panel via a first flexible circuit board, a control printed circuit board connected to the source printed circuit board via a second flexible circuit board, and a holder member arranged on the source printed circuit board to hold the control printed circuit board. According to this disclosure, it is possible to reduce movement of the control printed circuit board and prevent damage, during logistics transportation, by allowing stable fixation of the control printed circuit board.
