Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display modules generate significant heat that transfers to the exterior frame, leading to high temperatures exceeding 50°C, which affects the use experience and reduces the service life of the complete machine structure.
Innovation Solution
A complete machine structure design that includes a display module and exterior frame, where the total contact area between outer frame side edges and front frame side edges is controlled to limit heat transfer, using a thermal resistance equation to maintain the exterior frame temperature below 50°C, while ensuring structural strength through specific contact area and distribution of contact surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the contact area between outer frame side edges and front frame side edges is increased to enhance structural strength, then the strength of the complete machine exterior frame is improved, but the heat transfer from the display module to the exterior frame increases, causing the exterior frame temperature to exceed acceptable levels
Solution Approach 1:
The patent applies local quality by creating non-uniform contact between the outer frame side edges and front frame side edges. Specifically, the contact area is distributed unevenly along the length of the side edges, with larger contact areas positioned away from the display module and smaller contact areas near the display module. This localized variation in contact area allows the frame to maintain sufficient overall strength while limiting heat transfer from the high-temperature display module region.
2Temperature
If the contact area between outer frame side edges and front frame side edges is decreased to reduce heat transfer, then the exterior frame temperature is reduced, but the structural strength of the complete machine exterior frame is compromised
Solution Approach 1:
The patent applies parameter changes by precisely controlling the contact area parameter between outer frame side edges and front frame side edges. The total contact area is designed to satisfy a specific mathematical relationship with the display module power and thermal conductivity parameters. By optimizing this contact area parameter to a specific value or range, the patent achieves the dual objective of limiting heat transfer (keeping exterior frame temperature ≤50°C) while maintaining sufficient structural strength.
3Stability of the object's composition
If conventional complete machine structure is used with large contact area between frame components, then structural stability is maintained, but the exterior frame temperature exceeds 50°C after several hours of operation, reducing service life and user experience
Solution Approach 1:
The patent applies segmentation by dividing the contact area between outer frame side edges and front frame side edges into multiple distinct contact regions rather than a single continuous contact area. The contact surfaces are positioned at specific locations along the side edges, creating discrete contact points or regions. This segmented contact approach reduces the total heat transfer path while maintaining structural stability through distributed contact support.

AI summary
The present disclosure provides a complete machine structure, including a display module and a complete machine exterior frame. The display module includes a display panel and a front frame, the front frame including a front frame side edge on an outer side of a side edge of the display panel. The complete machine exterior frame includes at least one outer frame side edge each located on a side of the front frame side edge away from the display panel, and in contact with the front frame side edge. When a total contact area of all outer frame side edges and corresponding front frame side edges satisfies a certain condition, heat transferred from the display module to the complete machine exterior frame can be reduced by controlling the total contact area.
