Electronic Device Cover Guide Section Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In electronic apparatus assembly, protruding parts can interfere with engaging sections of covers, making assembly difficult due to contact issues, limiting the layout freedom of components.
Innovation Solution
Incorporating a guide section on the frame that allows engaging sections of the cover to contact it first, preventing collision with protruding parts and facilitating assembly by allowing the cover to be elastically bent and securely engaged.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If parts are mounted on the frame without protruding beyond the outer peripheral edge, then the engaging section can be positioned without collision, but the layout freedom of parts is reduced
Solution Approach 1:
The guide section is formed in advance on the frame at a position overlapping with the engaging section. This preliminary structural preparation allows the engaging section to be guided into the correct position during assembly, preventing collision with protruding parts before they can interfere with the engagement process.
Solution Approach 2:
The guide section acts as an intermediary element between the frame and the engaging section. It mediates the assembly process by providing a guiding surface that directs the engaging section along the correct path, preventing direct collision with protruding parts while maintaining layout flexibility.
2Reliability
If the engaging section is positioned to engage with the frame, then the cover is secured, but protruding parts may collide with the engaging section during assembly
Solution Approach 1:
The guide section is pre-formed on the frame to overlap with the engaging section's path. This preliminary preparation ensures that during assembly, the engaging section is guided along the correct trajectory before reaching the final engagement position, preventing collision with protruding parts.
Solution Approach 2:
The guide section serves as an intermediary structure that facilitates the engagement process. It provides a guiding surface that mediates between the moving engaging section and the stationary frame, ensuring smooth engagement without collision while maintaining reliable connection.
3Ease of operation
If the guide section is formed to overlap with the engaging section, then assembly is facilitated by guiding the engaging section, but the frame structure becomes more complex
Solution Approach 1:
The guide section is merged with the frame structure, forming an integrated component rather than a separate part. This combining of functions reduces the total number of components and simplifies the overall structure while still providing the guiding function necessary for easy assembly.
Solution Approach 2:
The guide section on the frame serves multiple functions: it provides structural support for the frame, guides the engaging section during assembly, and prevents collision with protruding parts. This multi-functionality reduces the need for additional specialized components, thereby reducing overall complexity.

AI summary
The present invention increases the degree of freedom in layout of parts possessed by an electronic apparatus. A lower cover (50) has a first engaging section (53A). An inner part (B) has a first edge section (S1) which is located under the first engaging section (53A) and which overlaps with the first engaging section (53A) in the vertical direction. The inner part (B) has a guide section (31) located below the first edge section (S1). The guide section (31) is formed such that when the lower cover (50) and the inner part (B) are combined together in the vertical direction, the guide section (31) comes into contact with a right wall section (52B) of the lower cover (50) and pushes the right wall section (52B) rightward so as to cause the first engaging section (53A) to move rightward beyond the first edge section (S1).
