Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices with deformable displays face challenges in preventing the inflow of foreign matter into gaps between the display and the housing, which can lead to static electricity buildup and other issues.
Innovation Solution
Incorporating a foreign matter prevention part between the display and the housing, which includes a conductive portion to discharge static electricity and a non-conductive portion to reduce foreign matter ingress, while being coupled to the housing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a deformable display is used to increase portability, then the electronic device becomes more compact and portable, but gaps form between the display and housing allowing foreign matter ingress
Solution Approach 1:
A foreign matter prevention part is introduced as an intermediary component between the deformable display and the housing. This part includes a contact portion that touches the display surface and a prevention portion that extends toward the housing to block foreign matter. The intermediary structure fills the gap created by display deformation while maintaining contact with the display, effectively preventing foreign matter ingress without restricting display movement.
Solution Approach 2:
The foreign matter prevention part is divided into distinct functional segments: a contact portion that interfaces with the display and a prevention portion that blocks foreign matter. This segmentation allows each part to perform its specific function optimally - the contact portion maintains display contact during deformation while the prevention portion creates a barrier against foreign matter.
2Adaptability or versatility
If the display is deformed into the housing, then portability is improved, but static electricity builds up in the gap between display and housing
Solution Approach 1:
The foreign matter prevention part serves as a mediator that simultaneously addresses foreign matter prevention and static electricity discharge. By incorporating a conductive portion that is electrically connected to the housing, the structure provides a discharge path for static electricity while maintaining the physical barrier function against foreign matter.
Solution Approach 2:
The foreign matter prevention part is constructed as a composite structure combining non-conductive material (for foreign matter prevention) with conductive material (for static electricity discharge). The conductive portion may be integrated into the non-conductive body or positioned adjacent to it, creating a multi-functional component that handles both foreign matter blocking and electrostatic discharge.
3Object-affected harmful factors
If a structure is added to prevent foreign matter inflow, then foreign matter protection is improved, but device complexity increases
Solution Approach 1:
The foreign matter prevention part is designed to perform multiple functions simultaneously: it acts as a physical barrier to block foreign matter, provides a conductive path to discharge static electricity, and maintains contact with the deformable display during movement. By consolidating these multiple functions into a single component, the overall device complexity is minimized while achieving comprehensive protection.
Solution Approach 2:
The foreign matter prevention part merges the barrier function (non-conductive portion blocking foreign matter) with the electrostatic discharge function (conductive portion connected to housing) into a unified structure. This merging eliminates the need for separate components for each function, reducing the number of parts and simplifying the overall device architecture.
