Solution Overview
Problem
Existing floor installation elements for electrical connections are complex and time-consuming to assemble due to the need for screw connections and small parts, making the process cumbersome and requiring specialized tools.
Innovation Solution
A floor installation unit with a lower part featuring bayonet recesses and an upper part with corresponding bayonet hooks, utilizing a spring element and latching lug for secure engagement without tools, allowing for quick and tool-free assembly and disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If screw connections are used to connect the lower part and upper part, then the connection is secure and stable, but the assembly process becomes complex and time-consuming requiring tools and small parts
Solution Approach 1:
The connection system is segmented into distinct functional elements: bayonet recesses in the lower part, bayonet hooks in the upper part, spring elements with latching recesses, and latching lugs. This segmentation allows each component to perform its specific function independently, enabling tool-free assembly while maintaining connection stability.
Solution Approach 2:
The spring elements automatically engage the latching lugs into the latching recesses when the bayonet hooks are inserted into the bayonet recesses. The system serves itself by using the insertion motion to compress the springs, which then automatically lock the connection without requiring additional tools or manual intervention.
2Reliability
If screw connections are used to connect the lower part and upper part, then the connection is secure, but assembly requires specialized tools and small parts that must be kept ready
Solution Approach 1:
Multiple connection functions are merged into a single integrated mechanism. The bayonet connection provides both positioning and initial engagement, while the spring elements with latching lugs provide automatic locking. This merging eliminates the need for separate screws, nuts, and tools, reducing device complexity while maintaining reliable connection.
Solution Approach 2:
The spring elements act as intermediaries between the bayonet hooks and the latching recesses. They mediate the connection by converting the linear insertion motion into the engagement of the latching lugs, providing a smooth transition that ensures reliable connection without complex assembly steps.
3Strength
If a secure connection is achieved through traditional methods, then the parts are firmly connected, but the assembly process is time-consuming
Solution Approach 1:
The bayonet hooks are pre-formed on the upper part and the bayonet recesses are pre-formed on the lower part during manufacturing. This preliminary preparation allows the connection to be made simply by inserting the upper part into the lower part and rotating, eliminating the need for time-consuming screw assembly operations and significantly increasing assembly speed.
Solution Approach 2:
The spring elements introduce dynamics to the connection system. They are compressed during insertion and then expand to lock the latching lugs in place. This dynamic mechanism allows for quick assembly and disassembly while maintaining strong connection strength, as the springs provide continuous locking force without requiring multiple fastening steps.
