Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vapor chambers and heat pipes in handheld devices cannot be bent or folded without risking damage and leakage, limiting their ability to be compacted for convenient carrying with large-scale touch screens or operation interfaces.
Innovation Solution
A bendable vapor chamber structure comprising multiple plate bodies connected by flexible connection bodies made of materials like polypropylene or flexible printed circuits, allowing the vapor chamber to be folded and unfolded without damage, with capillary structures and working liquid within a receiving space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If thin vapor chambers are used to conduct heat, then heat conduction performance is improved, but the vapor chambers cannot be bent or folded without risking damage and leakage
Solution Approach 1:
The vapor chamber is divided into multiple plate bodies (first plate body and second plate body) that are connected through a bendable connection structure, allowing the chamber to be segmented and folded without compromising the integrity of the heat conduction function
Solution Approach 2:
A flexible connection body is introduced between the plate bodies to provide bendability to the vapor chamber structure, enabling it to be folded while maintaining the sealed environment necessary for heat conduction
2Volume of moving object
If the vapor chamber is made thin to fit in handheld devices, then device compactness is improved, but the vapor chamber becomes fragile and cannot withstand bending
Solution Approach 1:
The thin vapor chamber is segmented into multiple plate bodies that can be connected and folded, distributing the mechanical stress of bending across multiple segments rather than concentrating it on a single thin structure
Solution Approach 2:
The vapor chamber structure combines rigid plate bodies with a flexible connection body, creating a composite structure that maintains the thin profile needed for compactness while adding bending resistance through the flexible connector
3Area of stationary object
If large-scale touch screens are used to improve device functionality, then user interface capability is improved, but device portability deteriorates
Solution Approach 1:
The vapor chamber is segmented into foldable plate bodies that can be collapsed when not in use, allowing large-scale devices with extensive touch screens to be compacted for portable storage similar to tablet computers
Solution Approach 2:
The vapor chamber structure transitions from a static rigid form to a dynamic foldable form, enabling the device to change its configuration between expanded (for functionality) and collapsed (for portability) states

AI summary
A bendable vapor chamber structure includes a first plate body and a second plate body assembly. The first plate body has a first face and a second face on upper and lower sides. The second plate body assembly has multiple plate bodies and at least one bendable connection body. The bendable connection body is disposed between the plate bodies and connected with the plate bodies. The second plate body assembly is correspondingly mated with the first plate body to together define a receiving space. A first capillary structure is disposed in the receiving space. A working liquid is filled in the receiving space. By means of the bendable connection body, the vapor chamber is bendable.
