Foldable Display Edge Protector With Damper Against Shock Contact
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Foldable electronic devices with flexible displays face damage due to direct contact and shock when transitioning between folded and unfolded states, necessitating a method to prevent such damage.
Innovation Solution
Incorporation of a protective member with a recess, damper, and fastener system along the edges of the display to absorb shocks and prevent direct contact between display regions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the flexible display is folded, then the device size is reduced for portability, but the display may contact itself and suffer damage from shock
Solution Approach 1:
A protective member is introduced as an intermediary component between the flexible display and the housing. This protective member includes a shock-absorbing member that physically separates the display from direct contact with the housing, preventing damage when the device is folded. The protective member acts as a mediator that absorbs the harmful shock while allowing the display to maintain its folding functionality.
Solution Approach 2:
The shock-absorbing member is pre-installed in a recess of the protective member before the display is assembled. This cushioning element is positioned in advance to absorb potential shocks that may occur during folding operations. The damper or elastic material is already in place to provide protective cushioning before any damage can occur to the display.
2Reliability
If a protective member is added to prevent display damage, then display durability is improved, but device complexity increases
Solution Approach 1:
The protective member integrates multiple functions into a single component structure. It combines the protective function (preventing display contact with housing), the shock-absorbing function (through the integrated shock-absorbing member), and the structural support function (maintaining display position). By merging these functions into one component, the overall device complexity is minimized while still achieving comprehensive protection.
Solution Approach 2:
The protective member is designed as a thin, flexible structure that can be easily integrated into the device without adding significant bulk or complexity. The shock-absorbing member within the protective member uses elastic materials or dampers that can deform flexibly to absorb shock, maintaining a sleek profile while providing robust protection.
