Floor Socket Bayonet Locking and Sealing Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connection floor boxes face issues with water ingress during cleaning, damaging electrical components, and are difficult to assemble, especially with small thread pitches and complex rotation requirements.
Innovation Solution
The integration of bayonet locking elements with complementary flange rings and a circumferential seal provides a watertight solution, allowing easy and quick assembly without tilting, and prevents cable twisting by requiring only a small rotational angle for fixation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a closed assembly position of the socket cover is used, then water sealing is improved, but assembly complexity increases due to threading requirements
Solution Approach 1:
The patent changes the connection parameter from threaded connection to bayonet locking connection. The bayonet locking elements (protrusions and recesses) enable quick assembly with a simple rotational motion, eliminating the need for complex threading operations while maintaining the closed assembly position for effective water sealing between the socket cover and base frame
Solution Approach 2:
The patent extracts the sealing function from the threading mechanism and implements it separately through a dedicated seal element positioned between the socket cover and base frame. This separation allows the bayonet locking elements to focus solely on mechanical connection and positioning, while the seal element independently provides water sealing, thereby reducing overall assembly complexity
2Manufacturing precision
If small thread pitch is used, then connection precision is improved, but assembly time increases due to multiple revolutions required
Solution Approach 1:
The bayonet locking mechanism allows the socket cover to be rapidly assembled with the base frame through a single rotational motion rather than requiring multiple revolutions of fine threading. The locking protrusions engage with corresponding recesses to provide precise positioning and secure connection in one quick action, significantly reducing assembly time while maintaining connection precision
3Reliability
If multiple turns are required for assembly, then connection security is improved, but cable twisting occurs in undesired manner
Solution Approach 1:
The bayonet locking elements are pre-configured with specific protrusion and recess geometries that guide the socket cover into the correct rotational position during assembly. This preliminary configuration ensures that cables can be routed straight through the connection without twisting, as the locking mechanism inherently establishes the proper orientation before final securing
