Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional dual electrical switch device is used, then the structure is simple and easy to set up, but the loading device cannot be remotely controlled and power usage cannot be calculated
Solution Approach 1:
The patent integrates multiple functions into a single switch device including remote control capability, power usage calculation, overload protection, and timer functionality. The control module serves multiple purposes: it controls switch operation, calculates power consumption, provides overload protection, and enables remote control reception, thereby resolving the contradiction between adding functionality and maintaining structural simplicity.
2Reliability
If conventional dual electrical switch device is used, then the structure is simple, but there is no design for protecting against overload
Solution Approach 1:
The control module continuously monitors the electrical parameters (current, power) and provides feedback control. When overload conditions are detected, the control module automatically adjusts the switch state or triggers protection mechanisms, enabling reliable overload protection without requiring separate complex protection circuits.
3Adaptability or versatility
If conventional dual electrical switch device is used, then the structure is simple, but it cannot work with touch device or set a timer for automatic power shutdown
Solution Approach 1:
The patent combines touch device interface and timer functionality with the dual switch control in a single integrated control module. The control module processes touch inputs, manages timer settings, and coordinates switch operation, thereby achieving high adaptability while avoiding the need for separate independent control systems that would increase overall device complexity.
4Measurement precision
If conventional dual electrical switch device is used, then the structure is simple, but the usage of power cannot be calculated
Solution Approach 1:
The control module performs self-measurement of power usage by monitoring the electrical parameters through the existing circuit paths. The device uses its own control circuitry to measure and calculate power consumption without requiring external measurement devices, thereby achieving precise measurement capability while maintaining relatively simple structure.
