Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If existing home automation switches replace existing electrical switches, then remote control and automation functions are improved, but device complexity and cost increase significantly
Solution Approach 1:
The invention divides the automation function into two separate components: the existing electrical switch remains unchanged for local control, while a separate wireless control module handles remote automation. This segmentation allows each component to perform its specialized function without the complexity of combining both in a single device.
Solution Approach 2:
The patent introduces a wireless communication intermediary that bridges the existing switch and the control system. The switch outputs are detected and transmitted wirelessly to remote devices, enabling automation without modifying the original switch complexity.
2Extent of automation
If home automation switches replace existing switches, then automation functionality is improved, but cost increases by approximately 100 times
Solution Approach 1:
The existing electrical switch serves itself by providing both local control functionality and serving as a signal source for wireless automation control. The switch's existing outputs are detected and reused to trigger automated responses, eliminating the need for expensive dedicated automation switches.
Solution Approach 2:
The existing electrical switch is made multi-functional by using it both for direct local control and as a trigger for wireless automated control. This universal usage maximizes the value of the existing inexpensive switch while achieving automation goals.
3Extent of automation
If existing switches are replaced with home automation switches, then remote operation capability is improved, but ease of operation deteriorates due to learning curve
Solution Approach 1:
Instead of making the physical switch complex with multiple buttons and displays, the invention inverts the approach by keeping the physical switch simple and familiar, while adding wireless remote control capabilities that can be operated from anywhere in the building using standard mobile devices.
4Shape
If existing switch faceplates are replaced to match new automation switches, then aesthetic consistency is improved, but loss of substance increases due to discarded materials
Solution Approach 1:
The wireless control module is designed to be installed in the existing electrical box alongside the existing switch, maintaining the original faceplate. This preliminary planning of the installation approach avoids the need to remove and discard existing faceplates.
