Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conductive metal is used for the electrostatic eliminator, then the electrostatic elimination effect is improved, but the design integrity is degraded due to lack of optical transparency
Solution Approach 1:
The patent applies composite materials by combining conductive resin with transparent resin to create an electrostatic eliminator that is both electrically conductive and optically transparent. The conductive resin provides the necessary electrostatic elimination properties while the transparent resin matrix allows light transmission, resolving the contradiction between electrostatic effectiveness and design integrity.
2Reliability
If vinyl chloride tape is used for the electrostatic eliminator, then the electrostatic elimination effect is improved, but the durability is reduced
Solution Approach 1:
The patent changes the material parameters by selecting conductive resin with specific properties (electrical conductivity, transparency, durability) to replace vinyl chloride tape. This parameter change enables the electrostatic eliminator to maintain effectiveness while achieving superior durability and resistance to environmental factors like water vapor.
3Reliability
If conventional electrostatic elimination technologies are used, then the electrostatic elimination effect is improved, but the effectiveness is reduced under low electrostatic pressure conditions
Solution Approach 1:
The patent changes the electrical conductivity parameter of the electrostatic eliminator material to optimize performance across different electrostatic pressure conditions. The conductive resin provides appropriate conductivity that maintains effectiveness both at high and low electrostatic pressures, improving adaptability to varying operational conditions.

Implementation Method 2
the self-discharging electrostatic eliminator, which is formed from the conductive metal mentioned in Japanese Patent No. 6168157, is substantially not optically transparent, and therefore may degrade the design. Further, the electrostatic elimination effect of the self-discharging electrostatic eliminator described in Japanese Patent No. 6168157 is exhibited through corona discharge
Implementation Method 3
the conductive resin electrostatic eliminator suppresses air flow separation from the vehicle body, enhancing operational stability and durability

AI summary
An aspect of the present invention provides a vehicle which includes: an electrostatic eliminator (2) that reduces a positive charge of a specific portion (1) or that charges the specific portion (1) with a negative charge, the specific portion (1) being defined as a portion to be positively charged at which a positively charged air flow that flows around a vehicle body during travel starts to vary from a flow along a surface of the positively charged vehicle body to a flow separated from the surface as negative charges are accumulated because of the external factors. The specific portion (1) is constituted from a conductive material with a surface resistance value that is less than a surface resistance value of the electrostatic eliminator (2). The electrostatic eliminator (2) is constituted from a conductive resin with a surface resistance value in a range of 102 Ω or more and less than 1011 Ω.
