Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Static electricity accumulation on a vehicle body due to friction and electrical equipment activation leads to degraded aerodynamic characteristics and performance, as the static electricity cannot be discharged to the road surface through tires made of electrical resistance materials like rubber.
Innovation Solution
A vehicle design incorporating a self-discharge device that produces ions of opposite polarity in airflow to neutralize static electricity, connected to the vehicle body through an earth cable and a conducting member, ensuring the electrical resistance between the self-discharge device and the vehicle body is maintained within specific predetermined values to facilitate effective neutralization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If tires made of electrical resistance material (rubber) are used to sustain the vehicle body, then the vehicle body is isolated from the road surface electrically, but static electricity accumulates on the vehicle body and cannot be discharged
Solution Approach 1:
A self-discharge device is introduced as an intermediary component between the vehicle body and the external environment. This device includes a discharge electrode that generates ions of opposite polarity to the accumulated static electricity, which then neutralize the charge on the vehicle body through the airflow, allowing discharge without direct electrical contact to the ground
Solution Approach 2:
The invention utilizes airflow (pneumatics) as a medium to transport ions generated by the self-discharge device to the vehicle body surface. The flowing air carries the oppositely charged ions that neutralize the static electricity, providing a discharge path through the air rather than through direct electrical contact
2Use of energy by moving object
If static electricity accumulates on the vehicle body, then electrical equipment can be charged, but repulsive force acts between the vehicle body and ionized airflow of same polarity, degrading aerodynamic characteristics
Solution Approach 1:
The invention converts the harmful effect of static electricity accumulation (which causes repulsive force and degrades aerodynamics) into a beneficial neutralization process. By introducing ions of opposite polarity through the self-discharge device, the static charge is neutralized, eliminating the repulsive force and restoring proper airflow characteristics while maintaining the ability to charge electrical equipment
