Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional soft X-ray static electricity removal apparatus is used, then soft X-rays can ionize air to remove static electricity, but soft X-rays may leak from the discharge port affecting human bodies
Solution Approach 1:
The soft X-ray shielding sheet is divided into multiple layers (first outer sheet, interlayer sheet, second outer sheet) with different functions. The first and second outer sheets provide primary shielding, while the interlayer sheet with bent passage provides additional shielding and ionized air flow path. This segmentation achieves effective soft X-ray blocking without requiring a single complex thick barrier.
Solution Approach 2:
The ionized air passage in the interlayer sheet is designed with bent portions that extend in the thickness direction of the sheet. This three-dimensional path allows ionized air to pass through while forcing soft X-rays to travel a longer, non-linear path, increasing attenuation without blocking the ionized air flow.
2Productivity
If the amount of ionized air discharged is increased to handle miniaturized semiconductors, then static electricity removal efficiency improves, but the structure becomes more complex
Solution Approach 1:
The soft X-ray shielding sheet performs multiple functions simultaneously: (1) shields soft X-rays from leaking to the outside, (2) provides a flow path for ionized air from supply ports to discharge port, (3) the bent passage increases soft X-ray attenuation while maintaining ionized air flow. This multi-functionality in a single component increases ionized air discharge capability without adding separate complex structures.
3Manufacturing precision
If the ratio of positive ions to negative ions is adjusted, then static electricity removal precision improves, but device complexity increases
Solution Approach 1:
By applying a potential difference between the container and soft X-ray shielding sheet, the ionization process parameters are changed. This electrical parameter adjustment controls the ratio of positive to negative ions generated, enabling precise control of ion composition without adding complex mechanical adjustment mechanisms.

AI summary
Provided is a soft X-ray static electricity removal apparatus that has achieved an increase in the amount of ionized air discharged, with a simple structure. A soft X-ray static electricity removal apparatus (1) includes a soft X-ray generation device (90), a container (10), a soft X-ray shielding sheet (20), and an insulating layer (50). The soft X-ray generation device generates soft X-rays (92). The container (10) has an outlet (12) from which ionized air (100) that has been ionized with the soft X-rays flows out. The soft X-ray shielding sheet (20) is used at the outlet of the container and includes a first outer sheet (30), an interlayer sheet (34), and a second outer sheet (40) which are formed of a material opaque to the soft X-rays. The first outer sheet has supply ports (32) for the ionized air formed therein; the interlayer sheet has an ionized air passage (38) formed therein, which includes ionized air inlet openings (36) that communicate with the supply ports; and the second outer sheet has a discharge port (42) formed therein, which communicates with the ionized air passage. The supply ports, the ionized air passage, and the discharge port communicate with each other to provide an ionized air transmission portion (44). The insulating layer insulates the soft X-ray shielding sheet and the container from each other.
