Solution Overview
Problem
Conventional filters face issues with clogging due to dust accumulation, which reduces filtration efficiency, and measurement errors occur due to gaps between the filter and its housing, making it difficult to determine the correct replacement interval.
Innovation Solution
A filter construction with a zigzag pleat portion and a flatter fold portion, incorporating a diffusing member with fragrance, antibacterial, or moisture-absorbing materials, and a sensor system to measure the air flow passing through, ensuring effective filtration and easy replacement interval detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional filter is used, then filtration is provided, but foreign bodies accumulate on the filter surface causing clogging and reduced filtration efficiency
Solution Approach 1:
The filter is designed with a detachable diffusion element that can be easily removed and replaced. When the diffusion element becomes saturated with collected foreign bodies, it is discarded and a fresh one is installed, allowing the filter structure itself to be reused while the consumable diffusion element is replaced.
Solution Approach 2:
The filter is divided into separate functional components: a reusable filter structure and a replaceable diffusion element. This segmentation allows the diffusion element to be independently replaced when saturated, maintaining overall filter efficiency without replacing the entire filter assembly.
2Measurement precision
If a sensor measures airflow to determine filter replacement interval, then monitoring is provided, but gaps between filter and housing cause measurement errors
Solution Approach 1:
A seal element is introduced as an intermediary component between the filter frame and housing. This seal element eliminates gaps and ensures that all airflow passes through the filter and diffusion element, providing accurate measurements without requiring complex adjustment mechanisms.
Solution Approach 2:
The seal element is made of a flexible material that can adapt to slight variations in the housing and filter frame dimensions, creating an effective seal that prevents bypass airflow and ensures accurate sensor measurements.
3Reliability
If the filter interface is convexly curved to make firm contact, then contact with housing wall is improved, but creases form in the filter fabric
Solution Approach 1:
The filter fabric is designed with sufficient flexibility to conform to the convexly curved interface without forming damaging creases. The material properties are selected to allow elastic deformation that maintains contact firmness while preserving fabric integrity.
Solution Approach 2:
The filter assembly uses a composite structure combining the filter fabric with a supporting frame that provides structural rigidity. This composite design allows the fabric to maintain firm contact through the frame's support while preventing crease formation that would compromise fabric integrity.
