Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Folding of a foldable display panel in a housing causes relative movement, leading to potential fractures and interference between the display panel and the housing, which complicates protection and functionality.
Innovation Solution
A display apparatus design featuring a foldable display panel with a first flat area and a second curved area, protected by optical and cover members, an elastic member, and a housing with grooves, along with a protective film and adhesive layers, to minimize interference and protect against fractures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display panel is made foldable to enable miniaturization and complex interfaces, then the device functionality and compactness are improved, but the display panel becomes susceptible to fractures and interference with the housing
Solution Approach 1:
A curved protective member is disposed between the display panel and the housing to prevent direct contact and potential fracture. The curved shape allows the protective member to deform elastically during folding, absorbing stress before it reaches the display panel. This prior cushioning measure resolves the contradiction by protecting the foldable display panel from fractures while maintaining its folding functionality.
2Volume of moving object
If the display panel is folded, then the device can be miniaturized, but the end position of the display panel changes causing interference with the housing
Solution Approach 1:
The curved protective member acts as an intermediary between the display panel and the housing. During folding, this protective member deforms elastically and prevents the display panel from directly contacting or interfering with the housing. This intermediary structure resolves the contradiction by enabling miniaturization through folding while preventing harmful interference with the housing.
3Reliability
If protective measures are added to prevent fractures, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The curved protective member serves multiple functions simultaneously: it protects the display panel from fractures, prevents interference with the housing during folding, and maintains the compact folded form factor. By combining these functions into a single component, the solution improves reliability without significantly increasing device complexity.
