Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a measuring instrument such as an oscilloscope is used to specify a spot affected by noise, then the accuracy of noise identification is improved, but the ease of operation deteriorates because specialist knowledge is required
Solution Approach 1:
The patent introduces a communication device as an intermediary between the electric apparatus and the control device. This communication device includes a detection part that automatically detects code errors in digital signals, serving as a mediator that translates complex noise effects into simple error count data that can be easily processed and analyzed without requiring specialist measurement instruments or expert knowledge
Solution Approach 2:
The patent replaces the mechanical/electrical measurement system (oscilloscope, noise data logger) with a software-based detection system. The detection part uses error detection codes embedded in digital communication signals to identify noise effects, substituting complex electrical measurement equipment with a simpler software-based error counting mechanism that is easier to operate
2Measurement precision
If a measuring instrument is used to identify a spot affected by noise, then the measurement precision is improved, but the device complexity increases due to the need for specialized equipment
Solution Approach 1:
The communication device serves multiple functions: it communicates control signals from the control device to the electric apparatus, transmits status information back to the control device, and simultaneously detects code errors to identify noise effects. This multi-functionality eliminates the need for separate specialized measurement instruments, reducing overall system complexity while maintaining noise detection capability
Solution Approach 2:
The communication device performs self-diagnosis by detecting code errors in its own digital signals. The detection part within the communication device automatically monitors the integrity of transmitted and received digital signals, allowing the system to self-identify noise-affected spots without requiring external measurement equipment
3Measurement precision
If noise identification is performed ex post facto using a measuring instrument, then the measurement precision is improved, but the loss of time increases because it cannot be done in real time
Solution Approach 1:
The detection part continuously monitors digital signals for code errors during normal operation of the environment forming device. Rather than performing periodic or post-operation measurements, the error detection occurs continuously as data is transmitted, enabling real-time identification of noise effects and immediate response without interrupting the useful action of the system
Solution Approach 2:
Error detection codes are embedded in advance within the digital signal structure before transmission. This preliminary incorporation of detection mechanisms allows the system to detect noise effects as they occur during normal operation, rather than requiring separate post-operation analysis, thus enabling real-time monitoring without additional measurement steps
