Code Element and Line Sensor Arrangement for Inclination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional surveying devices face challenges in precise inclination determination due to increased complexity and error sources from additional components, leading to reduced precision and accuracy in spatial orientation and alignment.
Innovation Solution
A compact sensor arrangement featuring a code element with a code pattern and a line sensor, rigidly connected at a specific spacing, allows for precise inclination determination by projecting the code pattern onto the line sensor, adapting sensitivity through geometric and optical spacing, and using a spacer component for stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If additional components are added to surveying devices for inclination determination, then measurement functionality is improved, but device complexity increases and measurement precision deteriorates due to increased error sources
Solution Approach 1:
The code element and line sensor are merged into a single rigidly connected unit with a fixed spacing of 1-10 mm, forming an integrated sensor arrangement that determines inclination through the relative positioning of these two components rather than requiring separate sensing mechanisms
Solution Approach 2:
The sensor arrangement uses a universal rigid connection structure that simultaneously provides mechanical support, defines the optical spacing, and establishes the geometric relationship between code element and line sensor, eliminating the need for additional alignment components
2Measurement precision
If additional components are added to surveying devices for inclination determination, then measurement functionality is improved, but accuracy deteriorates due to increased error sources
Solution Approach 1:
The invention extracts the essential inclination determination function from complex multi-component systems and implements it using only two core components (code element and line sensor) with a rigidly defined spacing, removing unnecessary intermediate components that could introduce errors
Solution Approach 2:
The patent replaces complex mechanical alignment systems with a rigidly connected structural arrangement where the spacing between code element and line sensor is fixed by design (1-10 mm), eliminating mechanical adjustment mechanisms and their associated error sources

AI summary
Embodiments of the invention include a sensor arrangement for inclination determination with respect to at least one axis. The sensor arrangement may include a code element having a code pattern and a line sensor, which is sensitive at least with respect to one wavelength range, having a reception direction orthogonal to its extension direction. In some embodiments the code element and the line sensor are arranged such that the extension direction of the line sensor and an extension direction of the code element are oriented in the same direction. The code element and the line sensor may be rigidly connected at a spacing of at least 1 mm and at most 10 mm such that a location, which is angle-dependent with respect to the reception direction, of a projection of the code pattern onto the line sensor can be determined by means of the line sensor.
