Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing composite processing machines lack effective protection for operators from glare during additive manufacturing and do not allow easy observation of the processing area, requiring additional safety measures and reducing visibility for operators.
Innovation Solution
A composite processing machine equipped with a light irradiator, a cutting machine, a cover, and a shading filter that changes its degree of shade based on light received, allowing for safe operation and observation during additive manufacturing and machining by using sensors to control door states and light transmissivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a shading wall is used to protect operators from light during additive manufacturing, then operator protection is improved, but visibility of the processing area deteriorates
Solution Approach 1:
The patent applies a variable shading filter that dynamically adjusts its light-blocking properties based on the operational state. During additive manufacturing, the filter increases shading to protect operators from glare. During machining operations, the filter reduces shading to improve visibility. This dynamic adaptation resolves the contradiction by making the protection level context-dependent rather than fixed.
Solution Approach 2:
The shading filter's optical parameters (light transmissivity, shading density) are changed based on the processing mode. The system transitions between different optical states: high shading during welding/additive manufacturing and low shading during machining. This parameter change allows the same component to serve dual purposes of protection and visibility enhancement.
2Object-affected harmful factors
If a shield plate is used to close the opening on the shading wall, then operator protection is improved, but observation capability deteriorates
Solution Approach 1:
The shield plate is replaced or supplemented with a variable shading filter that can dynamically adjust its transparency. Instead of a fixed opaque barrier, the filter can transition between opaque and transparent states, allowing operators to observe the processing area when protection is not critically needed while maintaining protection when harmful light is present.
Solution Approach 2:
The variable shading filter acts as an intermediary between the harmful light and the operator. Rather than completely blocking light with an opaque shield plate, the filter partially transmits light in a controlled manner, providing both protection and visibility simultaneously by mediating the light interaction.
3Object-affected harmful factors
If constant shading is applied during additive manufacturing, then operator protection is improved, but monitoring of processing conditions deteriorates
Solution Approach 1:
The shading filter dynamically adjusts its properties during additive manufacturing based on real-time conditions. When defects or anomalies occur, the filter can become more transparent to allow operators to visually monitor the processing area. During normal operation, it maintains high shading for protection. This dynamic response prevents information loss while maintaining protection.
Solution Approach 2:
The system incorporates feedback mechanisms that monitor processing conditions and adjust the shading filter accordingly. When sensors detect abnormal conditions or when visual monitoring is deemed necessary, the feedback loop triggers a change in filter transparency, allowing operators to observe the processing area without manual intervention to remove protective barriers.

AI summary
A machining tool includes a light irradiator, a cover, and a light blocking filter. The light irradiator is to irradiate a workpiece to process the workpiece. The cover covers the light irradiator and the workpiece in the cover. The light blocking filter is configured to change light transmissivity of the light blocking filter in accordance with light from an inside of the cover, which the light blocking filter receives.
