Display Cover Mounting via Regulating Portions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing displays face difficulties in mounting a cover member on a display panel support member due to the flat rear surface, leading to poor mounting workability and potential issues with dust ingress and light leakage.
Innovation Solution
Incorporating movement regulating portions such as recess portions, projecting portions, and upright portions on the display panel support member to guide and secure the cover member, improving positioning and station-keeping, while preventing dust and light leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the rear surface of the display panel support member is made flat, then the manufacturing process is simplified, but the mounting workability of the cover member deteriorates
Solution Approach 1:
The movement regulating portions (recesses and projections) are pre-formed on the display panel support member during manufacturing. This preliminary action enables the cover member to be automatically guided and positioned correctly during mounting, resolving the contradiction by preparing the mounting interface in advance without complicating the overall manufacturing process
Solution Approach 2:
The movement regulating portions act as intermediary elements between the display panel support member and the cover member. These intermediaries (recesses and projections) facilitate the mounting process by providing mechanical guidance and positioning, allowing the cover member to be mounted easily without requiring complex alignment procedures
2Device complexity
If the cover member is mounted on a flat rear surface, then the structural simplicity is maintained, but the positioning precision of the cover member deteriorates
Solution Approach 1:
The invention transitions from a two-dimensional flat surface to a three-dimensional structured surface by adding recesses and projections. This dimensional change provides multiple contact points and geometric constraints that automatically position the cover member with high precision while maintaining overall structural simplicity
Solution Approach 2:
The recesses and projections introduce geometric curvature and non-planar features to the otherwise flat surface. These curved and shaped features provide precise positioning surfaces that guide the cover member into correct alignment, achieving high positioning precision without significantly increasing device complexity
3Ease of operation
If movement regulating portions are added to the display panel support member, then the mounting workability is improved, but the device complexity increases
Solution Approach 1:
The movement regulating function is segmented into distinct recess portions and projection portions rather than using a single complex mechanism. This segmentation allows each feature to perform a specific function (guiding, positioning, or securing) independently, improving mounting workability while keeping the overall structural complexity manageable through modular functionality
