Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If cooled liquid heat dissipation is configured in the display device, then heat dissipation efficiency is improved, but assembly difficulty increases and sealing reliability deteriorates
Solution Approach 1:
The fixation assembly is designed to be rotatable around a rotation shaft, transitioning from a first state during assembly to a second state during operation. This dynamic mechanism allows the assembly process to be simple while automatically achieving reliable sealing and fixation once rotated into position.
Solution Approach 2:
The fixation assembly automatically seals and fixes the optical substrate when rotated to the second state, without requiring additional manual sealing operations. The system self-completes the sealing function through the rotation action, reducing assembly complexity while ensuring sealing reliability.
2Temperature
If cooled liquid heat dissipation is configured in the display device, then heat dissipation efficiency is improved, but sealing reliability for coolant deteriorates
Solution Approach 1:
The invention replaces traditional mechanical sealing methods (such as gaskets or adhesive sealing) with a rotation-based locking mechanism. The fixation assembly rotates to engage with the optical substrate, and the compression member automatically compresses to create a reliable seal, substituting complex mechanical sealing with a simpler rotational engagement system.
3Ease of manufacture
If traditional fixation methods are used for the optical substrate, then assembly is simple, but sealing of coolant cannot be ensured
Solution Approach 1:
The invention merges the fixation function and the sealing function into a single integrated fixation assembly. When the assembly rotates to the second state, it simultaneously achieves both mechanical fixation of the optical substrate and sealing of the coolant, eliminating the need for separate sealing components or steps.
Solution Approach 2:
The fixation assembly serves multiple functions: it acts as a rotation mechanism, a locking mechanism, and a sealing mechanism all in one component. This multi-functional design maintains assembly simplicity while ensuring coolant sealing reliability through the integrated compression member that seals when rotated into position.

AI summary
A display module is provided and includes: a backplane, defining a receiving slot; a light source assembly, arranged at a bottom of the receiving slot; an optical substrate, snapped to an upper portion of the accommodation slot, wherein a sealing cavity is defined between the optical substrate and the optical source assembly; a coolant, received in the sealing cavity; and a self-sealing fixation assembly, rotatably arranged on a slot wall of the receiving slot. In a first state, the optical substrate abuts against the self-sealing fixation assembly in a direction towards the bottom of the receiving slot; and, in a second state, the self-sealing fixation assembly is in an interference fit with the optical substrate, the self-sealing fixation assembly and the optical substrate are locked with each other to cooperatively define the sealing cavity.
