Solution Overview
Problem
Display devices, particularly large-sized ones, face challenges in heat dissipation efficiency and module replacement, which affect their performance and maintenance.
Innovation Solution
The design incorporates a control module that is movable between a frame and a back cover, with a bridge unit for electrical connection, and features like rails and stoppers for guided insertion, facilitating easy replacement and improved heat dissipation through a structured configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If the control module is fixed inside the display device, then the heat dissipation path is limited, but the replacement and maintenance become difficult
Solution Approach 1:
The control module is separated from the main device body and placed on a movable support structure, allowing it to be independently accessed and replaced without disassembling the entire display device. This segmentation enables easy maintenance while maintaining proper heat dissipation through the dedicated support structure.
Solution Approach 2:
The support structure is designed to be movable between an inserted position (for normal operation) and a pulled-out position (for maintenance). This dynamic capability allows the control module to be easily accessed for replacement while maintaining stable heat dissipation during operation.
2Ease of repair
If the control module is made movable for easy replacement, then maintenance becomes easier, but the electrical connection reliability may be compromised
Solution Approach 1:
The support structure is nested within the display device cavity when in the inserted position, creating a stable and compact configuration. The control module is nested on the support structure, allowing it to be easily removed with the support structure as a unit while maintaining reliable electrical connections through the bridge unit.
Solution Approach 2:
The bridge unit acts as an intermediary electrical connection component between the control module and the main device. This dedicated intermediary ensures reliable electrical connections during operation while facilitating easy disconnection and replacement during maintenance.
3Manufacturing precision
If a complex guiding structure is added for precise insertion, then the insertion accuracy improves, but the device complexity increases
Solution Approach 1:
The guiding protrusions and guiding grooves are designed with asymmetric shapes that provide precise directional guidance for insertion. The asymmetric design ensures the control module can only be inserted in the correct orientation, achieving high insertion accuracy without requiring complex multi-component guiding mechanisms.
