Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for identifying jet regulators face inaccuracies due to similarities in dimensions, leading to measurement inaccuracies caused by optical distortions and inclination, which complicates distinguishing between similar jet regulators.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If accurate measurement of jet regulator dimensions is performed using reference scale, then identification precision should improve, but optical distortions and inclination cause measurement inaccuracies that worsen identification reliability
Solution Approach 1:
The invention extracts and removes the problematic reference scale from the identification process entirely. Instead of measuring dimensions using a reference scale that is subject to optical distortions and inclination errors, the method directly analyzes the hole pattern geometry from the image without requiring external reference objects, thereby eliminating the source of measurement inaccuracies.
Solution Approach 2:
The invention inverts the traditional approach by not trying to achieve accurate measurements despite optical distortions, but rather by designing a measurement-independent identification method. Instead of correcting for distortion effects, the system uses distortion-tolerant hole pattern recognition that works directly with the captured image geometry.
2Manufacturing precision
If reference scale is used together with jet regulator in recording step, then dimension differentiation is enabled, but optical effects such as distortions and inclination result in measurement inaccuracies
Solution Approach 1:
The reference scale is completely removed from the recording and evaluation process. The invention achieves dimension differentiation through direct geometric analysis of the hole pattern itself, using the relative positions and dimensions of holes within the pattern to identify the jet regulator type without requiring external reference objects.
Solution Approach 2:
The invention uses the hole pattern itself as the identification key, creating a digital representation of the pattern geometry from the captured image. This digital copy of the hole pattern configuration serves as the basis for identification, replacing the need for physical reference scales and manual dimension measurements.
3Reliability
If hole pattern type and deviations are ascertained instead of accurate measurement, then identification accuracy improves, but requires complex image evaluation algorithms
Solution Approach 1:
The invention creates simplified digital representations of the hole patterns for comparison. By extracting key geometric features and creating standardized pattern templates, the system reduces the complexity of image evaluation while maintaining high identification accuracy through direct pattern matching rather than complex measurement algorithms.
Solution Approach 2:
The invention transforms the image evaluation from measuring absolute dimensions to analyzing relative geometric parameters of the hole pattern. By focusing on the configuration, spacing, and arrangement of holes rather than absolute measurements, the system simplifies the evaluation process while improving reliability by eliminating reference scale dependencies.

AI summary
A method for identifying a jet regulator (1) with improved precision and robustness is provided using a captured photo of a hole pattern (4) of an outlet structure (3) of the jet regulator (1). The captured photo is first compared with different stored hole pattern types (15) in a computer-implemented manner in a first step, and based on an evaluation of the respective degree of a match between the captured photo and each hole pattern type (15), the hole pattern type (15) on which the captured hole pattern (4) is based is ascertained. Subsequently, in another step, the ascertained hole pattern type (15) and the captured hole pattern (4) are examined for deviations in a computer-implemented manner, and identification information which uniquely identifies the jet regulator (1) is ascertained in a computer-implement manner using detected or undetected deviations and is optionally output.
