Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Air-conditioning apparatuses with poor sealing between the ventilation assembly and filter assembly experience condensation issues due to temperature differences, leading to user discomfort and maintenance challenges.
Innovation Solution
A filter assembly with a sealing part that matches the shape of the gap between the mounting portion and port, providing an interference fit to enhance sealing, and a detachable design for easy maintenance, using a combination of rigid and elastic materials for improved sealing and user convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a detachable filter assembly design is used to facilitate user maintenance and filter replacement, then ease of operation is improved, but sealing performance deteriorates due to gaps between the mounting portion and mounting port
Solution Approach 1:
The patent employs an elastic sealing ring as a flexible element that deforms to fill the gap between the rigid mounting portion and mounting port. The elastic material allows the sealing ring to compress and conform to the interface geometry, creating an effective seal while maintaining the detachable nature of the filter assembly for easy user replacement.
Solution Approach 2:
The sealing ring acts as an intermediary element between the mounting portion and mounting port. This intermediate component bridges the gap created by the detachable design, transferring the sealing function from a permanent integrated connection to a removable connection with an intermediate sealing element.
2Ease of manufacture
If a simple mounting structure is used to reduce device complexity, then ease of manufacture is improved, but sealing performance deteriorates due to insufficient sealing mechanisms
Solution Approach 1:
The elastic sealing ring provides an effective sealing solution that is simple to manufacture and integrate. The single-component elastic ring is easier to produce and install than complex multi-part sealing mechanisms, while still achieving reliable sealing through its elastic deformation capability.
Solution Approach 2:
The sealing mechanism relies on changing the physical state of the sealing ring through elastic deformation. By selecting appropriate elastic material properties and dimensions, the sealing ring can deform under compression to fill gaps and create a seal, achieving effective sealing through parameter optimization rather than complex structure.
