Cover Fixing Structure for Compact Display Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display apparatuses, such as audio and navigation devices, face challenges in compactly and securely fixing covers due to design constraints on installation space.
Innovation Solution
A compact fixing structure is achieved by incorporating a one-side cover with protruding fitting claws, an other-side cover with fitting sections, and a cover member with engagement holes, where the casing receives the fitting section from the inside of the other-side cover to maintain the engaged state of the fitting claw with the engagement hole.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a compact fixing structure is used, then the installation space is optimized, but the fixing strength may be insufficient
Solution Approach 1:
The fitting claw is inserted into the fitting section, and the engagement hole is formed within the fitting section structure. The casing receives the fitting section from the inside of the other-side cover, creating a nested arrangement where multiple components are housed within each other to maximize space utilization while maintaining structural integrity
Solution Approach 2:
The fixing structure is divided into distinct functional segments: the fitting claw on the one-side cover, the fitting section on the other-side cover, and the engagement hole in the cover member. This segmentation allows each component to perform its specific function efficiently within a compact overall structure
2Stability of the object's composition
If the cover is firmly fixed, then the structural integrity is improved, but the fixing structure becomes more complex
Solution Approach 1:
The fitting section integrates multiple functions into a single component: it receives the fitting claw, provides the engagement hole for the cover member, and is itself received by the casing. This merging reduces the number of separate parts needed while ensuring firm fixation
Solution Approach 2:
The engagement hole is formed in the cover member at a position that automatically engages with the fitting claw when assembled. The casing receives the fitting section from the inside of the other-side cover to maintain the engaged state, creating a self-maintaining fixed state without requiring additional active components

AI summary
A display apparatus is configured to enable a cover to be firmly fixed with a compact structure. The display apparatus includes: a one-side cover 16 that covers a casing 15 from one of front and rear sides; an other-side cover 17 that covers the casing 15 from the other of the front and rear sides; and a cover member 18 that covers the side surface of the one-side cover 16 from the periphery, wherein the one-side cover 16 includes a fitting claw 22 protruding to the other-side cover 17 side, the other-side cover 17 includes a fitting section 32 into which the fitting claw 22 is to be inserted, the cover member 18 includes an engagement hole 50 that engages with the fitting claw 22 in the fitting section 32, and the casing 15 receives the fitting section 32 from the inside of the other-side cover 17 to maintain an engaged state of the fitting claw 22 with the engagement hole 50.
