Solution Overview

Problem

Conventional temperature plates experience depression or deformation when bent, leading to a reduced contact surface and decreased heat dissipation efficiency due to the destruction of the wick structure on the inner wall.

Innovation Solution

A temperature plate design featuring a bent structure with a supporting structure, such as metal units or protruding/recess portions, to enhance the structural strength of the bent portion and prevent deformation, while maintaining a larger contact surface with the cooling fin assembly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If the plate body is bent to increase contact surface area, then the heat dissipation efficiency is improved, but the plate body experiences depression or deformation that reduces contact surface area

Engineering Contradiction:

Improvecontact surface areaVSAvoidplate body deformation

Core Design Contradiction:

Area of stationary objectVSStability of the object's composition

Solution Approach 1:

The plate body is divided into multiple sections with different bending radii. The first bent portion has a first bending radius while the second bent portion has a second bending radius different from the first, allowing each section to be optimized independently to prevent deformation while maintaining contact surface area.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different portions of the plate body are given different local geometric properties through varying bending radii. The first bent portion and second bent portion have distinct curvature characteristics tailored to their specific functional requirements, preventing uniform deformation across the entire structure.

Inventive Principle:

Principle #3Local quality

2Area of stationary object

If force is applied to bend the plate body, then the contact surface with cooling fin assembly is increased, but the wick structure on the inner wall is destroyed

Engineering Contradiction:

Improvecontact surface areaVSAvoidwick structure integrity

Core Design Contradiction:

Area of stationary objectVSReliability

Solution Approach 1:

The bending is segmented into multiple portions with different radii, distributing the mechanical stress across different sections rather than concentrating it in one area, thereby protecting the wick structure from destruction while still achieving the desired contact surface area.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The bending radius parameter is varied across different portions of the plate body. By changing the geometric parameter (bending radius) from uniform to variable, the stress distribution during bending is optimized to prevent wick structure damage while maintaining effective heat dissipation contact area.
