Device Housing Keyhole Locking for Tool-Free Stable Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing device housing connection systems require additional attachment parts and tools for assembly and disassembly, lacking ease and flexibility, especially in electronic device systems where multiple housings need to be connected and disconnected without compromising mechanical stability.
Innovation Solution
A system comprising at least three connection units with headed bolts and keyhole-shaped recesses, each equipped with a locking mechanism featuring a movable locking element that allows for tool-free assembly and disassembly, providing a mechanically stable and flexible connection without the need for additional brackets or tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If housings are screwed or bolted together with additional attachment parts, then mechanical stability is improved, but ease of assembly and disassembly deteriorates
Solution Approach 1:
The connection system is divided into multiple independent connection units (at least three), each comprising a headed bolt and a keyhole-shaped recess with a locking mechanism. This segmentation allows the connection to be distributed across multiple points, providing mechanical stability while keeping each individual connection unit simple and easy to operate.
Solution Approach 2:
The locking mechanism incorporates a movable locking element that can transition between locked and unlocked positions. This dynamic element enables easy assembly and disassembly without tools - the locking element is simply moved to release the connection - while maintaining a stable locked state during operation.
2Stability of the object's composition
If additional attachment parts such as mounting or fixing brackets are used, then mechanical stability is improved, but device complexity deteriorates
Solution Approach 1:
The connection units are integrated directly into the device housings themselves, with the headed bolts and keyhole-shaped recesses being part of the housing structure. This merging eliminates the need for separate mounting or fixing brackets, reducing device complexity while maintaining mechanical stability through the distributed connection units.
3Ease of operation
If headed bolt is inserted into keyhole-shaped recess, then ease of operation is improved, but locking reliability deteriorates
Solution Approach 1:
The locking mechanism is designed to be self-locking through the interaction between the headed bolt and the keyhole-shaped recess. When the headed bolt is inserted, the geometry of the recess and the movable locking element automatically engage to secure the connection without requiring external locking actions or additional components.

AI summary
A system is provided for releaseably connecting a first device housing with a second device housing. The system includes at least three connection units, wherein each of which includes a headed bolt and a corresponding keyhole-shaped recess. The keyhole-shaped recess is configured for receiving the headed bolt such that the headed bolt can be inserted into the recess in a first section and held in the recess in a second section. At least one of the connection units includes a locking mechanism configured for locking the bolt in the second section of the recess. The locking mechanism includes a movable locking element which is movable with respect to the headed bolt and configured to hold the headed bolt in the second section of the recess in a locking position. Another configuration uses a corresponding connection arrangement includes such a system.
