Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In low-humidity spaces, existing static electricity removal devices face inefficiency due to low moisture content, leading to ineffective ionized air distribution and ion collisions, which hinder static electricity removal.
Innovation Solution
A static electricity removal structure that supplies dehumidified air in a laminar flow through a blow port with a downstream static electricity removal device, using a blowout surface material with ventilation pores and alternating ion generation to prevent ion collisions, and is covered with a double structure curtain to maintain low humidity and reduce energy costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If dehumidified air is supplied at high wind speed to maintain low humidity, then humidity control is improved, but air flow becomes turbulent causing ion collisions and reducing static electricity removal efficiency
Solution Approach 1:
The patent applies dynamics by making the air flow regime changeable - switching from high wind speed turbulent flow to low wind speed laminar flow depending on the operational requirement. The system dynamically adjusts flow conditions to prioritize either humidity control or static electricity removal efficiency based on the dominant need at each moment.
Solution Approach 2:
The patent implements periodic action through alternating operation cycles: a first period dedicated to humidity control with high wind speed supply, followed by a second period dedicated to static electricity removal with low wind speed laminar flow. This periodic switching allows both conflicting requirements to be satisfied at different times in the operational cycle.
2Productivity
If static electricity removal device is applied in low-humidity space, then static electricity removal is attempted, but ionized air cannot be dispersed effectively due to low moisture content
Solution Approach 1:
The patent applies parameter changes by modifying the wind speed parameter from high to low during the static electricity removal period. This parameter change transforms the air flow from turbulent to laminar, enabling effective ionized air dispersion even in low-humidity conditions where moisture content is insufficient for natural ion transport.
3Quantity of substance
If dehumidified air is supplied continuously at high wind speed, then low humidity is maintained, but positive ions collide with negative ions and are eliminated
Solution Approach 1:
The patent uses periodic action to alternate between humidity maintenance mode (high wind speed) and static electricity removal mode (low wind speed). During the removal period, the reduced wind speed prevents ion collisions and elimination, allowing static electricity to be effectively removed before returning to humidity maintenance in the next cycle.
