Flexible Screen Temperature Equalization Plate Arching Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mobile terminals with temperature equalization plates experience arching issues over time, leading to poor user experience due to the plates squeezing the flexible screen, causing uneven heating and color differences.
Innovation Solution
A mobile terminal design featuring a flexible connection part on the temperature equalization plate, supported by a bending support part, which prevents the plate from contacting the flexible screen even when it becomes slack, using a screen reinforcing plate and accommodation slots to ensure the plate cannot touch the screen, and incorporating a redundant structure in the flexible connection part to manage tensile forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a temperature equalization plate is used to balance temperatures on two sides of the rotating shaft, then temperature uniformity is improved, but the plate becomes slack and arched over time, squeezing the flexible screen and affecting display quality
Solution Approach 1:
A bending support part is introduced as an intermediary component between the temperature equalization plate and the flexible screen. This support part prevents the plate from directly contacting and squeezing the screen while still allowing the plate to perform its temperature balancing function. The support part acts as a mediator that resolves the conflict between plate flexibility and screen protection.
Solution Approach 2:
The temperature equalization system is segmented into separate functional components: the temperature equalization plate for heat balancing, the bending support part for structural support, and the flexible connection part for accommodation. This segmentation allows each component to perform its specific function without interfering with others, preventing the plate from squeezing the screen while maintaining temperature uniformity.
2Adaptability or versatility
If the temperature equalization plate is made flexible to accommodate bending, then adaptability is improved, but the plate becomes slack and arched, causing harmful contact with the flexible screen
Solution Approach 1:
The bending support part serves as a mediator that allows the temperature equalization plate to be flexible and accommodate bending movements without directly transmitting these movements to the flexible screen. The support part absorbs the flexibility needed for adaptation while preventing harmful contact with the screen.
Solution Approach 2:
The harmful function of the flexible connection part (which causes arching and squeezing) is extracted and isolated by introducing the bending support part. The support part takes on the role of accommodating flexibility, while the temperature equalization plate maintains its primary function without causing harm to the screen.
3Device complexity
If elements with large volume are disposed on one side of the rotating shaft, then circuit simplification is achieved, but serious heating occurs on that side, causing color difference on the flexible screen
Solution Approach 1:
The temperature equalization plate changes the thermal parameters of the system by providing a thermal conduction path between the hot side (with large volume elements) and the other side. This parameter change enables heat redistribution, balancing temperatures on both sides of the rotating shaft while maintaining circuit simplification.

Function Achieved in This Case
This design effectively prevents the temperature equalization plate from arching and squeezing the flexible screen, maintaining a stable display and improving user experience by ensuring balanced heat distribution and reducing color differences across the screen.
Implementation Method 1
a temperature equalization plate is used to balance temperatures of parts that are of the flexible screen and that are located on two sides of the rotating shaft

AI summary
This application provides a mobile terminal. The mobile terminal includes a rotating member, a flexible screen, a bending support part, and a temperature equalization plate. The flexible screen includes two unfolded regions and a bent region located between the two unfolded regions, and the bent region is disposed opposite to the rotating member. The bending support part is located between the flexible screen and the rotating member, to support the bent region of the flexible screen. The temperature equalization plate includes temperature equalization parts opposite to the two unfolded regions in a one-to-one correspondence and a flexible connection part that connects the two temperature equalization parts. The flexible connection part is located on a side that is of the bending support part and that is away from the flexible screen, to balance temperatures in the two unfolded regions. The flexible connection part of the temperature equalization plate is distributed on the side that is of the bending support part and that is away from the flexible screen. Therefore, even if the temperature equalization plate is slack after being used for a long time, the temperature equalization plate cannot squeeze the flexible screen after being slack and arched, because the flexible connection part of the temperature equalization plate is blocked by the bending support part and cannot be in contact with the bent region of the flexible screen. Therefore, user experience is improved.
