Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic apparatus casings are difficult to assemble and lack robustness, which affects their mechanical strength and weight efficiency.
Innovation Solution
The electronic apparatus features a configuration with alternating ribs on frames that overlap in a specific direction, allowing for easy assembly and enhanced robustness by securing frames with screws at perpendicular directions, reducing weight and thickness while ensuring water-sealing performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If multiple plates and support plates are assembled using multiple screws in a conventional manner, then the casing achieves sufficient structural strength, but the assembly process becomes complex and time-consuming
Solution Approach 1:
The casing is divided into modular components (first plate, second plate, and multiple frames) that can be assembled independently. Each frame is a pre-assembled unit containing ribs, which simplifies the overall assembly process while maintaining structural integrity through the modular design.
Solution Approach 2:
Multiple ribs are integrated into a single frame structure, combining several structural elements into one assembly unit. This merging reduces the number of separate components that need to be handled during assembly, simplifying the process while preserving the cumulative strength of multiple ribs.
2Weight of stationary object
If the casing is made thinner to reduce weight, then the weight and thickness decrease, but the structural robustness and mechanical strength are compromised
Solution Approach 1:
The frame structure incorporates ribs with varying thicknesses and densities at different locations. Areas requiring higher strength have thicker or more densely arranged ribs, while areas with lower stress requirements use thinner ribs. This localized optimization allows the casing to be thinner overall while maintaining robustness where needed.
Solution Approach 2:
The frame structure combines multiple rib elements into a composite framework that provides enhanced strength-to-weight ratio. The alternating arrangement of ribs from adjacent frames creates a composite structural system that is both lightweight and mechanically strong.
3Strength
If ribs from adjacent frames are arranged to overlap alternately, then the structural robustness and water-sealing performance improve, but the manufacturing and assembly precision requirements increase
Solution Approach 1:
The ribs are pre-positioned and fixed within each frame during frame manufacturing, establishing their alternating overlap pattern before final casing assembly. This preliminary arrangement ensures precise alignment is achieved during frame production, reducing the precision burden on the final assembly process.
Solution Approach 2:
The alternating rib structure is designed to self-align during assembly, where the geometric configuration of the ribs guides their proper positioning. The interlocking nature of the alternating ribs provides inherent alignment features that reduce the need for high-precision manual adjustment during assembly.

AI summary
The frame 6 includes a top frame 6a, a reverse frame 6b, a right frame 6c, a left frame 6d, a front frame 6e, and a rear frame 6f which are separate components. The left frame 6d is moved in the direction of an arrow C to the front frame 6e and the rear frame 6f. Ribs provided at both end portions of the left frame 6d are inserted into ribs provided at end portions of the front frame 6e and the rear frame 6f. Similarly, the right frame 6c is also moved, and ribs are inserted into each other. In this manner, the four side frames are assembled. Then, the top frame 6a and the reverse frame 6b are assembled thereto. Since the ribs are inserted into each other as described above, the frame 6 is easily assembled and has excellent robustness.
