Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single sensor system is used to detect objects, then the device complexity is reduced, but the reliability of object detection deteriorates
Solution Approach 1:
The patent applies local quality by using different sensor types (first sensor and second sensor with different systems) to detect objects from different directions or with different characteristics. Each sensor is optimized for its specific detection task, improving overall detection reliability while maintaining reasonable system complexity through specialized rather than generalized sensing.
Solution Approach 2:
The patent implements prior cushioning by using multiple sensor systems to detect objects before making operational decisions. The operation control unit receives detection results from both sensor systems in advance, allowing it to cross-validate and confirm object presence, thereby cushioning against false detections or missed detections that could occur with a single sensor system.
2Reliability
If multiple sensor systems are used to detect objects, then the reliability of object detection is improved, but the device complexity increases
Solution Approach 1:
The patent merges the functionality of multiple sensor systems into a unified detection framework. The operation control unit integrates detection results from both the first and second sensors, combining their outputs to make operational decisions. This merging approach improves reliability through cross-validation while managing complexity by providing a unified control interface.
Solution Approach 2:
The operation control unit serves multiple functions: it processes detection results from both sensor systems, determines object presence based on combined data, and controls device operations. This multi-functionality reduces the need for separate control mechanisms for each sensor, thereby managing complexity while maintaining high detection reliability.
3Use of energy by moving object
If the autonomous mobile body remains stationary, then energy consumption is reduced, but the effectiveness of user communication deteriorates
Solution Approach 1:
The patent applies dynamics by enabling the autonomous mobile body to transition between stationary and moving states based on communication needs. When user communication or inducing actions are required, the body moves to engage users effectively; when communication is not needed, it remains stationary to conserve energy. This dynamic state adjustment optimizes both energy consumption and communication effectiveness.
Solution Approach 2:
The autonomous mobile body autonomously decides when to move and when to remain stationary based on its communication objectives and energy considerations. The operation control unit self-manages the balance between energy conservation and communication effectiveness by evaluating situational needs and initiating movement only when necessary for inducing actions or user engagement.

AI summary
An information processing apparatus includes a first sensor, a second sensor, an output device, and circuitry. The first sensor has a detection range in a first direction with respect to an autonomous mobile body, and the second sensor has a detection range in a second direction with respect to the autonomous mobile body, where the detection range of the first sensor in the first direction overlaps with the detection range of the second sensor in the second direction. Further, the output device presents information, and the circuitry controls an operation of the autonomous mobile body based on a first detection result of the first sensor and a second detection result of the second sensor.
