Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the user manually positions the optical sensor without motor assistance, then the device complexity is reduced, but the ease of operation deteriorates due to difficulty in setting suitable distance and orientation
Solution Approach 1:
The patent implements feedback by providing haptic resistance through the motor assistance system that gives the user tactile information about the sensor's position relative to the measurement object. The motor assistance actively communicates position information back to the user through controlled resistance forces, enabling the user to intuitively maintain optimal sensor positioning without complex manual calculations or adjustments.
Solution Approach 2:
The motor assistance system acts as an intermediary between the user's manual positioning actions and the sensor's actual position. Instead of directly controlling the sensor through complex electronic interfaces, the motor assistance provides tactile feedback that mediates the interaction, allowing the user to naturally sense and maintain optimal positioning through haptic cues.
2Measurement precision
If the user manually adjusts sensor position without haptic feedback, then the device complexity is reduced, but the measurement precision deteriorates due to difficulty in maintaining optimal sensor positioning
Solution Approach 1:
The haptic feedback mechanism provides continuous tactile information to the user about the sensor's relative position to the measurement object. This feedback loop enables the user to maintain precise sensor positioning by sensing haptic cues that indicate when optimal capture conditions are achieved, thereby improving measurement precision through intuitive physical feedback rather than complex electronic control systems.
3Ease of operation
If motor assistance with haptic feedback is implemented, then the ease of operation improves, but the use of energy increases due to continuous motor operation
Solution Approach 1:
The motor assistance operates periodically rather than continuously, activating only during sensor positioning operations and deactivating when positioning is complete. The haptic feedback is provided as intermittent tactile cues rather than continuous resistance, allowing the motor to remain inactive during stable positioning phases, thereby significantly reducing overall energy consumption while maintaining ease of operation during critical positioning tasks.

AI summary
A method for operating an optical sensor, which has a movement controller that can be actuated by a user to control a movement of the sensor relative to a measurement object, includes identifying that the sensor is in a favorable state of movement relative to the measurement object, and generating and outputting a signal when the sensor is in the favorable state of movement to assist the user in keeping the sensor in the favorable state of movement, and/or inhibiting or blocking by machine a movement of the sensor which would cause the sensor to leave the favorable state of movement. To achieve a favorable orientation of the sensor, generating and outputting a third signal signals to the user to actuate the movement controller such that the sensor achieves the favorable orientation, and/or controlling by machine a movement of the sensor which causes the sensor to achieve the favorable orientation.
