Solution Overview
Problem
The existing display apparatus faces issues with damage to circuit boards during the attachment and detachment process due to the use of double-sided adhesive tape, which can lead to errors and instability during assembly and delivery.
Innovation Solution
A display apparatus design that uses a heat sink plane with a coupling groove and guide holder on a guide panel to detachably couple the circuit board, eliminating the need for double-sided adhesive tape and providing a stable and secure attachment mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If double-sided adhesive tape is used to attach the circuit board, then the circuit board can be fixed to the display panel, but the circuit board may become damaged during attachment and detachment
Solution Approach 1:
The attachment system is divided into separate components: a coupling groove structure on the display panel and a corresponding coupling protrusion on the circuit board. This segmentation allows the circuit board to be attached and detached without direct adhesive contact, preventing damage while maintaining secure fixation.
Solution Approach 2:
The coupling groove and guide holder act as intermediary structures between the circuit board and display panel. These intermediaries provide a mechanical interface that secures the circuit board during attachment/detachment operations, eliminating the need for double-sided adhesive tape and preventing circuit board damage.
2Ease of manufacture
If double-sided adhesive tape is used to attach the circuit board, then the circuit board can be fixed, but errors and instability occur during assembly and delivery
Solution Approach 1:
The attachment mechanism is segmented into distinct coupling features (groove and protrusion) that enable precise alignment and secure attachment. This segmentation provides stable and repeatable assembly operations, eliminating the instability and errors associated with adhesive tape application.
Solution Approach 2:
The coupling groove and guide holder structure provides self-aligning and self-fixing capabilities during assembly. The guide holder automatically guides the circuit board into the coupling groove, ensuring proper positioning and stable attachment without requiring additional assembly steps or adhesive materials.
3Ease of operation
If a detachable coupling structure is used instead of adhesive tape, then the circuit board can be easily attached and detached, but the structure becomes more complex
Solution Approach 1:
The coupling structure is segmented into simple, geometric features (coupling groove and coupling protrusion) that are easy to manufacture and assemble. This segmentation allows for easy attachment and detachment operations while keeping the overall structure relatively simple and integrated with existing display panel components.
