Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing processing apparatuses fail to effectively form structures on objects by irradiating them with processing lights, as they lack precise control over the irradiation process based on the object's surface characteristics, leading to inconsistent results and reduced efficiency in forming riblet structures for reducing surface resistance.
Innovation Solution
A processing apparatus equipped with a light irradiation system that adjusts the irradiation state based on surface characteristics, using a control apparatus to measure and respond to the object's surface features, allowing for precise formation of riblet structures by altering the thickness or removing parts of the surface coating through controlled processing light exposure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional processing apparatus irradiates surface with processing light without measurement control, then processing can be performed, but manufacturing precision and consistency are poor
Solution Approach 1:
The patent applies preliminary action by measuring surface characteristics (roughness, curvature, temperature) before irradiation and using this information to pre-adjust irradiation parameters. This ensures high manufacturing precision from the start without requiring complex real-time control systems during processing.
Solution Approach 2:
The patent implements feedback by using measurement apparatus to detect surface characteristics and feeding this information back to the control apparatus, which then adjusts irradiation parameters accordingly. This closed-loop control achieves high precision while keeping device complexity manageable through selective measurement points.
2Productivity
If processing light is applied to form structures on surface, then surface resistance is reduced, but surface coating durability may be compromised
Solution Approach 1:
The patent applies partial action by selectively irradiating only specific regions where structures are needed, rather than treating the entire surface uniformly. This targeted approach reduces surface resistance efficiently while preserving coating durability in non-irradiated areas.
Solution Approach 2:
The patent implements local quality by adjusting irradiation parameters based on local surface characteristics measured at different positions. This allows optimal structure formation in each region while minimizing damage to the surface coating, achieving both productivity and strength requirements.
3Manufacturing precision
If irradiation parameters are fixed without adjustment, then processing is simple, but processing accuracy varies with surface characteristics
Solution Approach 1:
The patent applies self-service by enabling the processing system to automatically adjust its own parameters based on measurement feedback. The control apparatus autonomously modifies irradiation settings according to measured surface characteristics, achieving high precision without increasing operational complexity for the user.
Solution Approach 2:
The patent implements parameter changes by dynamically adjusting irradiation parameters (intensity, duration, pattern) based on measured surface characteristics such as roughness, curvature, and temperature. This adaptive approach maintains processing simplicity while achieving high accuracy through automated parameter optimization.
