Eliminator Blade with Offset Ends to Reduce Length and Pressure Loss
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional eliminators have a long blade length and width, leading to increased size, weight, and manufacturing costs, with issues such as pressure loss and flow resistance due to abrupt air direction changes and deflected air flow.
Innovation Solution
The eliminator design features blades with a first and second end part positioned on different lines, a gently curved guide part, and collecting members to filter moisture, ensuring smooth air flow and reduced weight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the blade is designed with V-shape or W-shape to filter moisture, then moisture filtering performance is improved, but the blade length from front-to-rear increases
Solution Approach 1:
The blade design transitions from conventional V-shape or W-shape configurations to a linear shape with collecting members positioned at specific locations. This dimensional reconfiguration allows moisture collection functionality to be achieved without increasing the front-to-rear blade length, as the collecting members are strategically placed along the blade surface rather than requiring extended blade geometry.
2Reliability
If the blade length and width are increased to improve moisture collection, then moisture filtering capability is improved, but the overall size and weight of the eliminator increases
Solution Approach 1:
Instead of uniformly increasing blade dimensions throughout the entire structure, the invention applies collecting members at specific local positions on the blade surface. This localized approach concentrates moisture collection functionality where most needed, achieving effective moisture removal without proportionally increasing overall blade area and weight.
Solution Approach 2:
The blade structure is segmented into functional zones: the main blade body for air passage and specific collecting member positions for moisture collection. This segmentation allows optimization of each zone's function independently, reducing unnecessary material usage while maintaining effective moisture collection performance.
3Reliability
If the moisture collecting structure faces the air flow directly, then moisture collection efficiency is improved, but pressure loss of air flow increases
Solution Approach 1:
Instead of having the moisture collecting structure face the air flow directly (conventional approach), the invention inverts the arrangement by positioning collecting members to collect moisture that condenses on the blade surface as air passes by. This indirect collection method reduces flow resistance while maintaining moisture collection effectiveness.
4Ease of operation
If the blade is inclined or bent to face air inlet and outlet in opposite directions, then air flow guidance is improved, but flow resistance increases due to abrupt direction change
Solution Approach 1:
The invention employs curved guide surfaces at the blade edges instead of abrupt angular transitions. These curved surfaces gently redirect air flow from the inlet to outlet direction, reducing turbulence and flow resistance while maintaining effective air flow guidance through the eliminator.

AI summary
A blade arranged between a first cover and a second cover. The blade includes a first end part that guides air inflow, a second end part that guides air outflow, and a guide part connecting the first and second end parts. The first and second end parts are positioned on different lines based on the air inflow direction. This configuration allows for a reduction in the front-to-rear length of the blade, thereby achieving a decrease in the product's weight.
