Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual wiring is used between the COP and junction box, then electrical connection is established, but maintenance complexity increases and installation becomes time-consuming
Solution Approach 1:
The electrical connection system is segmented into modular connector portions: a first connector portion integrated with the COP and a second connector portion integrated with the enclosure. This segmentation allows independent handling and connection of components, eliminating complex manual wiring and enabling simple plug-and-play installation and maintenance.
Solution Approach 2:
Connector portions serve as intermediary elements between the COP and the enclosure's junction box. These standardized connectors simplify the electrical interface, replacing complex wire harnesses with standardized plug-and-play connections that are easy to install and maintain.
2Adaptability or versatility
If complete replacement of elevator car enclosure is performed for COP updates, then aesthetic updates and feature additions are achieved, but cost and time increase significantly
Solution Approach 1:
The COP is designed as a separable module with integrated connector portions that interface with the enclosure. This allows the COP to be independently removed, updated, or replaced without affecting the enclosure structure, enabling quick feature additions and aesthetic updates without complete enclosure replacement.
Solution Approach 2:
The standardized connector portions provide universal electrical and data interfaces that can accommodate different COP configurations and updates. This universality allows flexible adaptation of the COP for various features and aesthetics while maintaining compatibility with the same enclosure structure.
3Productivity
If manual wiring procedures are used, then electrical connections are established, but installation time and operational downtime increase
Solution Approach 1:
Connector portions are pre-integrated into the COP and enclosure during manufacturing, with electrical contacts and alignment features prepared in advance. This preliminary action eliminates the need for complex wiring procedures during installation, allowing quick plug-and-play connection that significantly reduces installation time and operational downtime.
