Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If nondestructive inspection is performed to evaluate treatment target state, then productivity is improved by reducing unnecessary processing, but device complexity increases due to additional inspection equipment
Solution Approach 1:
The patent performs nondestructive inspection (magnetic evaluation and stress measurement) before shot processing to evaluate the treatment target state in advance. This preliminary evaluation identifies targets that already have adequate surface properties, allowing the system to skip unnecessary shot processing and improve productivity while managing device complexity through targeted inspection.
2Manufacturing precision
If shot processing is performed on all treatment targets, then manufacturing precision is maintained, but productivity decreases due to processing targets that do not require treatment
Solution Approach 1:
The patent applies shot processing selectively based on local evaluation of each treatment target's surface side state. By using nondestructive inspection to assess magnetic properties and stress levels, the system identifies which specific targets need treatment and which already meet specifications, thereby maintaining manufacturing precision while improving productivity by avoiding unnecessary processing.
3Measurement precision
If destructive inspection is used to verify treatment results, then measurement precision is achieved, but productivity decreases due to total inspection requirements
Solution Approach 1:
The patent replaces destructive inspection methods with nondestructive inspection techniques, specifically magnetic evaluation and stress measurement. These nondestructive methods provide sufficient measurement precision for evaluating surface side state and treatment target conditions without requiring physical damage to the targets, thereby maintaining quality control while improving productivity.

AI summary
A surface treatment processing method includes: a shot processing step of performing shot processing of shooting shot media at a treatment target; a first inspection step of nondestructively inspecting at least one of a surface side state and an external dimension of the treatment target subjected to the shot processing, evaluating that the treatment target is passed when an inspection result is within a first normal range set in advance, evaluating that the treatment target is failed when the inspection result is out of a first allowable range set in advance to include the first normal range, and evaluating that the treatment target is to be additionally processed when the inspection result is out of the first normal range but within the first allowable range; and an additional processing step of performing the shot processing again on the treatment target which is evaluated to be additionally processed.
