Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If non-ionized air is blown around the working tool, then air protection is provided, but electrostatic charges are not neutralized
Solution Approach 1:
The patent changes the physical-chemical parameter of the air from non-ionized to ionized state. The ionized air flow, generated by an ionizing device, actively neutralizes electrostatic charges on the panel and surrounding surfaces, preventing electrostatic discharges while maintaining air protection.
Solution Approach 2:
Ionized air acts as an intermediary substance between the electrostatic charges and the environment. The ionized particles in the air flow transfer charge to neutralize the electrostatic buildup on insulating materials, serving as a mediator that safely dissipates harmful charges.
2Object-affected harmful factors
If partitioning members define a volume around the working tool, then air protection is improved, but residual materials obstruct air passage paths
Solution Approach 1:
The partitioning members are made movable rather than fixed, allowing them to adapt their position dynamically. They can move to accommodate residual materials while maintaining the protective volume, and can be repositioned to restore optimal air flow paths as work progresses.
Solution Approach 2:
The partitioning members are divided into multiple segments or sections that can move independently. This segmentation allows different parts of the partition to adapt to residual materials in different zones while maintaining overall air protection, and facilitates restoration of air passage paths.
