Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual adjustment with adjusting screws is used to achieve high positioning accuracy, then the positional accuracy of the light-sensitive plane is improved, but the device complexity and labor requirements increase significantly
Solution Approach 1:
The patent applies preliminary action by pre-determining the position transformation of the electro-optical sensor before final assembly. The position transformation is calculated based on measured deviations of the light-sensitive plane from its desired position, and this transformation data is stored for later use in automatically compensating for positioning errors, eliminating the need for complex manual adjustment mechanisms
Solution Approach 2:
The patent replaces the mechanical adjustment system (adjusting screws and manual operations) with a computational approach. The position transformation data is used to automatically compensate for positioning errors through software-based image evaluation and computer-aided movement, substituting mechanical complexity with information processing
2Manufacturing precision
If manual adjustment process is implemented to achieve required tolerances, then the positioning accuracy is improved, but the productivity and time consumption decrease
Solution Approach 1:
The patent implements feedback by using software-supported evaluation of test images to automatically determine the position transformation of the sensor. This feedback loop allows the system to automatically adjust and optimize sensor positioning based on measured deviations, eliminating the need for iterative manual adjustments and significantly improving productivity
Solution Approach 2:
The system performs self-service by automatically evaluating test images and calculating the required position transformation without requiring technically qualified personnel to manually adjust each sensor. The computer-aided movement system autonomously positions sensors based on the determined transformation parameters
3Adaptability or versatility
If multiple electro-optical sensors are aligned on a single sensor holder, then the imaging capability is improved, but the complexity and time required for adjustment increases
Solution Approach 1:
The patent applies universality by developing a standardized method that can be applied to multiple electro-optical sensors on a single sensor holder. The same position transformation determination and compensation approach is universally applicable to each sensor, allowing consistent and efficient alignment of multiple sensors without requiring different adjustment procedures for each one
Data Source
AI summary
A sensor arrangement including at least one electro-optical sensor which is secured to a receiving structure of a sensor holder. The electro-optical sensor includes a sensor housing with an optically active sensor layer that is arranged thereon. The optically active sensor layer forms a light-sensitive plane. The sensor holder includes a non-adjustable receiving structure which compensates for a previously determined deviation in shape of the electro-optical sensor from a desired shape.
