Casing Assembly Engaging Elements for Screwless Structural Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional casing assemblies for electronic devices are complex and time-consuming to assemble and disassemble, require numerous screws for secure connection, and have limited space due to thick engagement junctions, leading to deformation and restricted layout for electronic components.
Innovation Solution
A casing assembly design featuring engaging elements with concave and protruded slabs and sidewalls that connect securely without screws, providing structural strength and reducing the thickness of the junction, allowing for enhanced space utilization and simplified assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If multiple screws are used to connect the two casings, then the connection strength is improved, but the assembly complexity and time increase
Solution Approach 1:
The patent combines multiple screw connections into a single engagement element that performs the function of multiple screws. The engagement element includes a body with multiple engagement portions that can simultaneously connect to corresponding portions on the other casing, merging multiple fastening functions into one integrated component.
Solution Approach 2:
The engagement element serves multiple functions simultaneously: it provides structural connection, restricts movement in multiple directions (horizontal and vertical), and eliminates the need for separate screws. This multi-functional design reduces assembly complexity while maintaining connection strength.
2Strength

AI summary
A casing assembly includes a first casing and a second casing. The first casing includes a first lateral plate and a first engaging element. The first engaging element includes a first slab, a first sidewall and a second sidewall. The first sidewall and the second sidewall are connected with the first lateral plate. Moreover, a dent is formed between the first lateral plate and the first engaging element. The second casing is combined with the first casing. The second casing includes a second lateral plate and a second engaging element. The second engaging element includes a second slab, a third sidewall and a fourth sidewall. The third sidewall and the fourth sidewall are connected with the second lateral plate. The second engaging element is accommodated within the dent and in contact with the first engaging element, so that the first casing and the second casing are combined together.
