Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for effective and practical methods to accurately and efficiently determine the dimensions of regular patterns of elements in recording apparatuses, particularly to avoid undesired overlaps or gaps when merging sub-images, which is challenging due to variations in image element placement and visual characteristics.
Innovation Solution
A method involving a sensor to sample the regular pattern, providing multiple data sample sets with varying numbers of samples, analyzing these samples to determine spatial frequencies, selecting a quantified value, and using it to determine the dimension of the pattern, thereby ensuring precise positioning of sub-images.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple data sample sets with varying numbers of samples are analyzed to determine spatial frequencies, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent divides the dimension determination process into multiple independent data sample sets, each containing a different number of samples. By analyzing each sample set separately to determine spatial frequencies and then combining results, the system achieves higher measurement precision while managing complexity through modular processing of segmented data portions.
2Productivity
If recording heads with increasing numbers of marking elements are used to increase productivity, then productivity is improved, but manufacturing precision deteriorates due to placement errors and visual characteristic variations
Solution Approach 1:
The patent employs a sensor to sample the actual regular pattern of elements on the recording media and determine the true spatial frequency and dimension. This feedback information about actual placement characteristics is used to compensate for placement errors and visual characteristic variations, maintaining manufacturing precision even as productivity increases through higher element counts.

AI summary
A method for determining a dimension of a regular pattern of elements, wherein the elements in the regular pattern are arranged along an arrangement direction with a first spatial frequency includes providing a sensor for sampling the regular pattern; providing a plurality of data sample sets, wherein each data sample set includes data samples provided by the sensor while sampling over a portion of the regular pattern, and each data sample set consists of a different number of data samples; analyzing each data sample set to determine a corresponding spatial frequency; determining a plurality of quantified values, each quantified value being associated with a different one of the determined spatial frequencies; selecting a first quantified value from the plurality of quantified values; and determining the dimension based at least on the selected first quantified value.
