Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If electromagnetic sensors are fixed to a rotating half-arc with computer processing, then field measurement capability is improved, but measurement time and complexity increase
Solution Approach 1:
The patent replaces the mechanical computer processing system with an optical display system. Electromagnetic sensors detect field values, which directly control light sources to create visual representations of the electromagnetic field. This substitution eliminates the need for deferred computer processing, enabling real-time visualization and significantly reducing measurement time while maintaining measurement capability.
2Measurement precision
If electromagnetic sensors are fixed to a rotating half-arc with computer processing, then field measurement capability is improved, but device complexity increases
Solution Approach 1:
The patent replaces the complex mechanical computer processing system with a simpler optical system. Sensors are directly coupled with light sources through optical elements, eliminating the need for computers, software processing, and complex data management. This substitution maintains field measurement capability while significantly reducing device complexity.
3Speed
If light sources emit light based on measured field in real-time, then visualization speed is improved, but need for computer processing is eliminated
Solution Approach 1:
The patent replaces the computer processing system with a direct optical coupling system. Sensors detect electromagnetic field values and immediately translate them into light intensity or color variations through optical elements. This real-time translation eliminates the need for computer processing while achieving instantaneous visualization, as the optical system directly converts electrical sensor signals into visual output without digital intervention.
4Ease of manufacture
If assumptions are made for sensor calibration, then initial setup is simplified, but repetitive operations are required if calibration is incorrect
Solution Approach 1:
The patent implements a self-calibrating system where the optical display provides immediate visual feedback of the electromagnetic field. This real-time visualization allows operators to observe field patterns directly and adjust sensor positioning or calibration intuitively without relying on assumptions. The system serves itself by providing direct visual information that guides proper setup and calibration, eliminating the need for repetitive operations if initial assumptions are incorrect.
