Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing clearer systems for textile machines have complex and difficult-to-handle optical setups, along with complex housings that limit their optical capabilities, are resource-intensive to assemble, and are prone to disturbances.
Innovation Solution
The proposed illumination receiving system features a simplified optical setup with a housing designed for ease of assembly, where the receiving cavity is configured to receive shadow projections or reflected light, and a photosensitive electronic component measures the incoming illumination without direct line of sight to the light source, allowing for decoupling of the aperture size and sensor size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a complex optical setup with multiple lenses and diffusing foils is used, then measurement precision is improved, but device complexity increases and ease of manufacture deteriorates
Solution Approach 1:
The patent extracts and removes the complex optical components (multiple lenses, diffusing foils, aperture assemblies) from the measurement system, replacing them with a simple receiving cavity that directly captures light. This extraction eliminates unnecessary optical elements while preserving measurement functionality through the cavity's geometric design and non-specular surface properties.
Solution Approach 2:
The receiving cavity is segmented into distinct functional zones: an opening for light entry, non-specular surfaces for light redistribution, and a sensor placement area. This segmentation allows each zone to perform its specific function independently, achieving precise measurements through the coordinated action of simple geometric components rather than complex optical assemblies.
2Adaptability or versatility
If a complex housing design is used, then optical capabilities are improved, but ease of operation deteriorates and resource costs increase
Solution Approach 1:
The patent merges the housing structure with the optical receiving function by designing the receiving cavity as an integral part of the housing. The housing itself becomes the light-receiving structure with built-in non-specular surfaces, eliminating the need for separate complex optical assemblies and making the system easier to operate and maintain.
Solution Approach 2:
The receiving cavity serves multiple functions simultaneously: it acts as the housing structure, the optical element for light capture and redistribution, and the measurement chamber. This multi-functionality provides versatile optical capabilities while simplifying the overall system design and operation.
3Measurement precision
If multiple optical components are assembled, then measurement accuracy is improved, but productivity deteriorates due to tedious assembly
Solution Approach 1:
The patent removes multiple optical components (lenses, diffusing foils, aperture assemblies) from the assembly process, replacing them with a single receiving cavity structure. This extraction dramatically reduces the number of parts to be assembled while maintaining measurement accuracy through the cavity's geometric design.
Solution Approach 2:
Multiple optical functions (light capture, diffusion, focusing, and measurement) are merged into a single receiving cavity component. This consolidation reduces the assembly process to installing one component rather than assembling multiple separate optical elements, significantly improving productivity.
4Use of energy by moving object
If the aperture size is increased, then light capture is improved, but the photo sensitive component size must also increase
Solution Approach 1:
The non-specular surfaces of the receiving cavity act as an intermediary between the aperture and the photo sensitive component. These surfaces redirect and redistribute incoming light rays, allowing a large aperture to capture abundant light while the cavity's internal geometry concentrates and redirects this light onto a small sensor area, decoupling aperture size from sensor size.
