Electronic Apparatus Bezel Sidewall Disassembly Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic apparatus with a one-piece structure, where the bottom wall and sidewall are integrated, face challenges in reducing size due to the thickness increase caused by screw clearance holes used for fixing a glass frame, making it difficult to achieve a compact design while allowing disassembly.
Innovation Solution
The design incorporates a bezel that presses inward on the sidewall section, allowing the sidewall to be bent outward and return to its original position upon detachment, enabling the removal of the light transmissive member with minimal force without the need for screws, and optionally includes an elastic member and interposed member to enhance flexibility and rigidity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If screw clearance holes are provided in the barrel to fix a glass frame, then the glass plate can be detached for disassembly, but the thickness of the barrel increases making it difficult to achieve compact design
Solution Approach 1:
The sidewall is divided into a first sidewall section (upper portion) and a second sidewall section (lower portion), with the light transmissive member inserted between them. This segmentation allows the light transmissive member to be detached without requiring screw clearance holes, thereby maintaining compact barrel thickness while enabling disassembly.
Solution Approach 2:
The light transmissive member is nested between the first and second sidewall sections, utilizing the space created by the segmented sidewall structure. This nesting approach eliminates the need for additional screw clearance holes, achieving both compact design and disassemblability.
2Length of stationary object
If the sidewall is made thin for compact design, then the apparatus size is reduced, but the structural strength and rigidity decrease
Solution Approach 1:
The first sidewall section is designed with different properties than the second sidewall section. The first sidewall section is made flexible to enable bending for disassembly, while the second sidewall section maintains sufficient thickness and rigidity to provide structural strength. This local differentiation allows the thin-walled compact design to maintain adequate strength.
3Ease of operation
If the sidewall is made flexible to enable bending for disassembly, then the light transmissive member can be detached with small force, but the structural rigidity of the case decreases
Solution Approach 1:
The sidewall is segmented into two sections with different mechanical properties. The first sidewall section (upper) is designed to be flexible for easy bending during disassembly, while the second sidewall section (lower) maintains rigidity to preserve overall case stability. This segmentation resolves the contradiction between disassembly ease and structural rigidity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach allows for a compact, disassemblable electronic apparatus with improved flexibility and rigidity, enabling the light transmissive member to be detached with reduced force, while maintaining a one-piece structure without increasing the apparatus' size.
Implementation Method 1
the first sidewall section is pressed outward by the light transmissive member, so that the first sidewall section is bent outward. In other words, detachment of the bezel removes the pressure exerted by the bezel on the first sidewall section, and the first sidewall section bent inward by the inward pressure exerted by the bezel attempts to return to the original position before the assembly.

AI summary
An electronic apparatus includes a case (case body) including a bottom wall and a sidewall integrated with each other, having an opening, and having a receiving surface provided as part of the sidewall and along the circumferential edge of the opening, a light transmissive member that covers the opening and is placed on the receiving surface, and a bezel provided in a position outside the sidewall that forms the receiving surface and so attached to the case as to be pressed toward the sidewall.
