Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices face challenges in maintaining improved visibility and reliability, particularly when incorporating modules like cameras, while minimizing the increase in peripheral areas and maintaining aesthetic appeal.
Innovation Solution
The electronic device incorporates a display module with a higher light transmittance transmission area, a lower film, a protective member with module holes, and cover patterns surrounding these holes, which can be rings, to enhance visibility and protect internal components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a transmission area with higher light transmittance is provided, then visibility is improved, but the peripheral area increases
Solution Approach 1:
The patent introduces a cover pattern layer disposed between the lower film and the protective member, creating an additional dimensional layer that selectively blocks light. This cover pattern layer allows the transmission area to maintain high light transmittance for visibility while the cover pattern itself defines the peripheral boundary, effectively managing the peripheral area through a new spatial dimension in the stack structure.
Solution Approach 2:
The cover pattern acts as an intermediary element between the transmission area and the peripheral region. It is disposed specifically between the lower film and the protective member, serving as a mediator that allows light to pass through the transmission area while blocking light from reaching the peripheral area, thus resolving the contradiction between visibility and peripheral area management.
2Illumination intensity
If the lower film is made transparent for visibility, then light transmission is improved, but interference from the lower film increases
Solution Approach 1:
The cover pattern serves as an intermediary layer positioned between the lower film and the protective member. It mediates the interaction between light and the lower film by blocking light paths that would cause interference while allowing beneficial light transmission through the transmission area, thus reducing harmful interference effects.
Solution Approach 2:
The cover pattern extracts and blocks specific light paths that cause interference from the lower film. By selectively blocking these interfering light paths through the cover pattern's geometric design, the patent removes the harmful interference effect while preserving the overall light transmission function.
3Adaptability or versatility
If electronic modules are added to enhance functionality, then device capability is improved, but reliability decreases due to increased complexity
Solution Approach 1:
The electronic module is nested within the protective member, which itself is part of the layered structure containing the cover pattern and lower film. This nested arrangement protects the electronic module from external damage while keeping it integrated within the existing structure, thus improving device capability without significantly compromising reliability.
Solution Approach 2:
The cover pattern and protective member act as intermediary protective layers between the external environment and the electronic module. These intermediaries protect the electronic module from damage, thereby maintaining reliability even as device capability is enhanced through the addition of electronic modules.
