Back Cover Latch Assembly for Display Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices face challenges in easily assembling components, particularly in coupling a back cover to the frame element, which complicates the manufacturing process and increases costs.
Innovation Solution
The display device incorporates a guide panel with latch assemblies that include ribs to restrict movement of the back cover, allowing for easy coupling without additional coupling members like screws, using a combination of first, second, and third ribs to secure the back cover in place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional coupling methods (screws, additional coupling members) are used to attach the back cover, then the attachment strength and reliability are improved, but the assembly complexity and manufacturing cost increase
Solution Approach 1:
The patent merges the coupling function directly into the back cover and frame structures by forming latch assemblies through protrusions and recesses that are integrated parts of the components themselves, eliminating the need for separate coupling members like screws while maintaining secure attachment
Solution Approach 2:
The back cover and frame perform their own coupling function through self-complementary latch assemblies where the protrusion on the back cover engages with the recess in the frame, allowing the components to secure themselves without requiring additional fastening hardware
2Reliability
If traditional coupling methods are used to attach the back cover, then the attachment strength is improved, but the manufacturing cost increases
Solution Approach 1:
The coupling functionality is merged into the existing back cover and frame components through integrally formed latch assemblies, eliminating the need to manufacture and assemble separate coupling members, thereby reducing manufacturing steps and costs while maintaining secure attachment
Solution Approach 2:
The patent extracts the coupling function from separate fastening components and incorporates it directly into the back cover and frame structures, allowing the main components to serve dual purposes (structural support and coupling mechanism) which simplifies manufacturing and reduces part count
3Stability of the object's composition
If multiple ribs are used in latch assemblies to restrict back cover movement in multiple directions, then the stability of back cover attachment is improved, but the structural complexity increases
Solution Approach 1:
The latch assembly is segmented into multiple functional ribs (first rib for horizontal restriction, second rib for vertical restriction, third rib for front-back restriction) that work independently to constrain the back cover in different directions, providing comprehensive stability while keeping each rib's structure simple and straightforward
