Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the apparatus uses a fixed optical axis alignment between the irradiator and detector, then the device complexity is reduced, but the measurement precision deteriorates due to misalignment between actual and estimated emission directions
Solution Approach 1:
The patent implements a dynamic optical axis adjustment mechanism where the irradiator and detector can independently change their emission and detection directions. This allows the system to adapt the optical axes in real-time to maintain precise alignment between actual and estimated emission directions, resolving the contradiction between measurement precision and device complexity by making the system flexible rather than fixed
Solution Approach 2:
The patent changes the emission direction parameters of the irradiator and detector dynamically. By adjusting these parameters based on the relationship between actual and estimated emission directions, the system achieves high measurement precision without requiring overly complex mechanical structures, as the adjustment is controlled through parameter modification rather than physical reconfiguration
2Productivity
If the apparatus separately measures distance and image information at different timings, then the device complexity is reduced, but the productivity deteriorates due to repeated measurements being required
Solution Approach 1:
The patent enables continuous simultaneous acquisition of both distance and image information by coordinating the irradiator and detector to operate together. This eliminates the need for repeated separate measurements, significantly improving productivity while maintaining manageable device complexity through integrated control of the dual detection functions
Solution Approach 2:
The patent merges the distance measurement function and image information acquisition function into a single coordinated operation. By combining these functions so that both types of data are obtained simultaneously in one measurement cycle, the system achieves high productivity without requiring separate measurement systems, thus avoiding excessive complexity
3Measurement precision
If the apparatus uses a single detector for both distance and image detection, then the device complexity is reduced, but the measurement precision deteriorates due to inability to separately optimize detection axes
Solution Approach 1:
The patent segments the detection function into two specialized detectors: one optimized for distance measurement and another for image information acquisition. This segmentation allows each detector to be independently aligned and optimized for its specific function, achieving high measurement precision for both distance and image data while managing complexity through functional specialization rather than requiring a single complex multi-functional detector

AI summary
An electromagnetic wave detection apparatus (10) includes an irradiator (11), a first detector (17), a memory (19), and a controller (20). The irradiator (11) irradiates electromagnetic waves. The first detector (17) includes detection elements. The detection elements detect, by irradiation position, reflected waves of the electromagnetic waves irradiated on an object (ob). The memory (19) stores first related information including an emission direction of the emitted electromagnetic waves. The controller (20) updates the first related information based on the position of the detection element, among the detection elements, that detects the reflected waves of the electromagnetic waves.
