Solution Overview
Problem
Existing swimming pool lighting systems face practical implementation challenges and risk electrical degradation due to complex screwing mechanisms and twisting of power cables during installation.
Innovation Solution
A lighting system with a cylindrical sleeve wall crossing member and a lighting device featuring a fitting connection with interlocking means and a sealing system to secure the power cable, allowing for easy assembly and preventing electrical degradation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a screw fixing mechanism is used to attach the lighting device to the wall crossing member, then the lighting device can be securely fixed, but the power cable may twist and degrade during the screwing operation
Solution Approach 1:
The fixing mechanism is divided into two independent parts: a fixing ring that attaches to the wall crossing member and a fitting connection that attaches to the lighting support. This segmentation allows the power cable to pass through the fitting connection independently without being affected by the screwing operation of the fixing ring, thus preventing cable twisting while maintaining secure fixation.
Solution Approach 2:
The power cable is routed through the fitting connection before the final tightening of the fixing mechanism. The fitting connection is designed to accommodate and guide the cable in its initial position, preventing it from becoming entangled or twisted during the subsequent screwing operation of the fixing ring.
2Reliability
If a complex screwing mechanism with multiple components is used, then the lighting device can be firmly attached, but the installation process becomes difficult and time-consuming
Solution Approach 1:
The attachment system is segmented into a fixing ring with external threading and a fitting connection with internal threading. This segmentation allows each component to be independently assembled: the fixing ring is screwed onto the wall crossing member while the fitting connection is attached to the lighting support, simplifying the installation process while maintaining firm attachment.
Solution Approach 2:
The fitting connection serves multiple functions: it provides a secure attachment point for the lighting support and simultaneously serves as a cable conduit. This multi-functionality reduces the number of separate components needed, simplifying the overall installation process while ensuring reliable attachment.
3Reliability
If the power cable passes through the lighting support during assembly, then electrical connection is established, but the cable may become twisted or damaged during the fixing operation
Solution Approach 1:
The assembly process is segmented into two independent operations: attaching the fitting connection to the lighting support (which accommodates the cable) and screwing the fixing ring to the wall crossing member. This segmentation ensures the cable remains protected within the fitting connection during the screwing operation, preventing twisting or damage while maintaining electrical connectivity.
Solution Approach 2:
The fitting connection acts as an intermediary structure that protects the power cable during assembly. It provides a dedicated pathway for the cable and isolates it from the mechanical stresses of the screwing operation, thereby preventing cable damage while ensuring reliable electrical connection.
