Flexible Connecting Piece for Foldable Display Housings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flexible electronic devices with foldable displays often have low appearance consistency due to gaps in the rotating shaft assembly, affecting user experience and aesthetics.
Innovation Solution
An electronic device design featuring a flexible connecting piece made of soft materials like silica gel, with strategically placed slits on the housings and connecting piece, allowing for seamless folding and flattening while maintaining a regular appearance texture, and incorporating magnetic attachment assemblies and memory metal pieces for structural support and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a rotating shaft assembly is used to enable folding, then the device can be folded and flattened, but gaps appear on the bent part reducing appearance consistency
Solution Approach 1:
The patent replaces the rigid rotating shaft assembly with a flexible connecting piece made of soft material (silica gel). This flexible piece allows the housing to be folded and flattened while maintaining appearance consistency, as it can be seamlessly integrated into the housing structure without creating visible gaps like traditional rotating shafts would.
Solution Approach 2:
The patent changes the material parameter of the connecting piece from rigid (metal rotating shaft) to flexible (soft silica gel). This parameter change enables the connecting piece to deform during folding without creating gaps, thus maintaining appearance consistency while preserving folding capability.
2Shape
If a flexible connecting piece is used instead of a rotating shaft, then appearance consistency is improved, but structural strength may be reduced
Solution Approach 1:
The patent uses silica gel, a material with unique properties combining flexibility and sufficient structural strength. The flexible connecting piece made of silica gel provides both the needed flexibility for folding without gaps and adequate structural strength to support the device during folding and flattened states.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design enhances appearance consistency, reduces the device's size and weight, improves user experience by allowing flexible form factors, and ensures reliable operation with enhanced structural strength and durability.
Implementation Method 1
The flexible connecting piece can be deformed, so that the first housing and the second housing are folded or flattened relative to each other
Implementation Method 2
incorporating magnetic attachment assemblies and memory metal pieces for structural support and stability

AI summary
The application discloses an electronic device, including a flexible display, a first housing, a second housing, and a flexible connecting piece, where two sides of the flexible connecting piece are connected to the first housing and the second housing, and the flexible display is fastened to the first housing, the flexible connecting piece, and the second housing. A plurality of first slits are disposed on a side that is of the first housing and that faces away from the flexible display; a plurality of second slits are disposed on a side that is of the second housing and that faces away from the flexible display; a plurality of third slits are disposed on a side that is of the flexible connecting piece and that faces away from the flexible display; and extension directions of the first slit, the second slit, and the third slit are parallel to a first direction.
