Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If AC to DC converter and electronics are incorporated into standard switch and outlet boxes for building automation, then networking and control capabilities are enabled, but heat generation occurs which creates fire hazard and harms electronics operation
Solution Approach 1:
The patent extracts the heat-generating AC to DC converter from the enclosed switch and outlet box by implementing it as an external wall-mounted power supply unit. This external placement removes the source of harmful heat away from the confined box space, eliminating the fire hazard and thermal damage to electronics while preserving the networking and control capabilities within the box.
Solution Approach 2:
The patent introduces an intermediary external power supply unit that provides DC power to the electronics within the switch and outlet box through a connection that separates the heat-generating conversion process from the sensitive electronic components. This intermediary approach allows the box to contain only low-power electronics while the high-power conversion occurs externally.
2Ease of manufacture
If AC to DC converter is enclosed within standard switch and outlet boxes, then power control circuitry is integrated, but the converter generates heat that constitutes a fire hazard
Solution Approach 1:
The patent extracts the fire-hazardous AC to DC converter from the enclosed box and relocates it to an external wall-mounted unit. This maintains the ease of integration by providing a dedicated external power supply that connects to the box, while eliminating the fire hazard by removing the high-power conversion process from the confined enclosed space.
3Adaptability or versatility
If conventional networking systems are installed in pre-existing buildings, then network coverage is achieved, but cable routing is difficult and expensive or wireless repeaters are required
Solution Approach 1:
The patent implements a universal wall-mounted module that combines multiple functions: AC to DC power conversion, wireless communication interface, and building automation control. This multi-functional device eliminates the need for separate cable routing and wireless repeaters by providing integrated network coverage through the wall-mounted units that can communicate wirelessly with each other and with central control systems.
Solution Approach 2:
The patent replaces the mechanical cable routing system with a wireless communication network. The wall-mounted modules communicate with each other and with building automation systems via wireless protocols, eliminating the need for physical cable installation through building structures and removing the complexity of routing cables in pre-existing buildings.
4Adaptability or versatility
If standard outlet boxes are used for building automation electronics, then existing infrastructure is utilized, but the boxes cannot accommodate the electronics required for networking
Solution Approach 1:
The patent extracts the networking electronics from the enclosed standard outlet box and places them in an external wall-mounted module. This allows the standard outlet box to be used as intended while the external module provides the additional networking and control electronics, thus utilizing existing infrastructure without the complexity of modifying the boxes themselves.
