Electronic Housing Bottom Cover with Screwless Locking Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional notebook computer housing designs require screws for assembly and disassembly, which are inconvenient and time-consuming due to the need for multiple screws and complex screw hole alignments.
Innovation Solution
A screwless locking structure featuring a sliding or rotating locking member with a control button and locking plate that engages and disengages a positioning element, allowing easy assembly and disassembly of the bottom cover to the housing body without screws.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If screws are used to fasten the bottom cover to the housing body, then the connection strength is sufficient, but the assembly and disassembly process becomes inconvenient and time-consuming
Solution Approach 1:
The patent removes screws entirely from the fastening system and replaces them with a screwless locking mechanism. The locking member engages with positioning elements through a snap-fit design, eliminating the need for threaded fasteners and their associated tools, thereby dramatically improving ease of assembly and disassembly while reducing time consumption.
Solution Approach 2:
The locking member is designed to automatically engage with the positioning elements when the bottom cover is installed, creating a self-locking mechanism. The elastic portion of the locking member provides automatic retention force without requiring additional fastening operations, allowing the structure to serve itself in maintaining the assembled state.
2Ease of operation
If a screwless locking structure is used, then assembly and disassembly convenience is improved, but the locking reliability must be maintained
Solution Approach 1:
The locking member incorporates curved engagement surfaces and rounded positioning elements that facilitate smooth engagement and disengagement. The curved geometry of the elastic portion allows it to deform elastically during assembly and maintain consistent contact pressure, ensuring reliable locking while enabling easy operation.
Solution Approach 2:
The locking mechanism utilizes elastic deformation of the locking member as a key parameter change. By controlling the material properties and geometric dimensions of the elastic portion, the design achieves optimal balance between engagement force (for reliability) and release force (for ease of operation), allowing the same structure to provide both strong locking and easy assembly.

AI summary
A housing for an electronic device includes a housing body, a bottom cover, and a locking member. The housing body includes an engaging slot and a through hole. The bottom cover includes an engaging hook for engaging the engaging slot. An inner surface of the housing body or the bottom cover is provided with a positioning element. The locking member extends through the through hole, and includes an engaging portion disposed on the inner surface of the housing body, and a control portion exposed from the through hole. The control portion is operable to move the engaging portion between a locking position where the engaging portion engages the positioning element and an unlocking position where the engaging portion is separated from the positioning element to thereby facilitate assembly and disassembly of the bottom cover to and from the housing body.
