Electronic Housing Locking Structure for Screwless Bottom Cover Access
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 multiple accommodation slots and covers.
Innovation Solution
A screwless locking structure featuring a sliding or rotating locking member with a locking plate and control button, allowing easy engagement and disengagement of the bottom cover from the housing body without screws.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If screws are used to fasten the cover to the housing body, then the connection strength is improved, but the assembly and disassembly time increases and convenience decreases
Solution Approach 1:
The locking member is designed to be movable between a locking position (where it engages the positioning element to secure the cover) and an unlocking position (where it releases the positioning element). This dynamic mechanism allows quick transition between locked and unlocked states, eliminating the time-consuming screw assembly/disassembly process while maintaining connection strength when locked.
Solution Approach 2:
The invention extracts and eliminates the screws from the fastening system. Instead of using multiple screws to fasten the cover, a single locking member with engaging portion is used to engage with the positioning element, providing both secure connection and quick release capability without requiring any screw tools.
2Reliability
If multiple screws are used for each accommodation slot, then the reliability of fastening is improved, but the device complexity and number of parts increases
Solution Approach 1:
The locking member integrates multiple functions into a single component: it provides locking engagement through the engaging portion, allows for quick release via the control portion, and replaces multiple screws across different accommodation slots. This merging reduces the number of parts while maintaining fastening reliability through the engaged locking mechanism.
Solution Approach 2:
The locking member serves multiple purposes: it acts as a fastening element, a locking mechanism, and a release system all in one component. The engaging portion provides secure attachment, while the control portion enables easy release, making the single component replace multiple specialized parts.
3Device complexity
If conventional screw fastening is used, then the structural simplicity is maintained, but the ease of operation for assembly and disassembly deteriorates
Solution Approach 1:
The locking member acts as an intermediary mechanism between the cover and housing body. Instead of directly using screws that require tool operation, the locking member provides a simplified interface where the control portion can be operated manually to engage or disengage the engaging portion from the positioning element, greatly improving ease of operation.

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.
