Twist-Lock Filter Body for Compact Gas Sampling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gas sampling systems face challenges in accommodating replaceable filters due to space constraints, especially in compact setups, and require additional external space or necessitate instrument servicing for filter replacement.
Innovation Solution
A replaceable filter with an integral accessory receptacle that can be inserted into a filter receptacle within the gas sampling apparatus, allowing for user-accessible filter replacement without additional external space, utilizing a twist-lock mechanism for secure insertion and connection to a gas supply.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an external filter is placed near the instrument panel for easy replacement, then filter accessibility is improved, but additional space beyond the sample line connector is required
Solution Approach 1:
The filter body is merged with the accessory receptacle into a single integrated component. The accessory receptacle is formed integral with the filter body, allowing the filter to be housed within the filter receptacle without requiring additional external space on the instrument panel.
Solution Approach 2:
The filter body containing the filter element is nested within the filter receptacle. When the filter body is fully inserted, only the accessory receptacle protrudes from the filter receptacle, creating a compact nested arrangement that eliminates the need for additional external space.
2Area of stationary object
If the filter is located internally of the measurement apparatus, then space on the instrument panel is saved, but the instrument must be serviced for filter replacement
Solution Approach 1:
The filter body is extracted as a removable component from the filter receptacle. The filter body can be easily removed by disengaging the twist-lock mechanism, allowing users to replace the filter without servicing the entire measurement apparatus.
Solution Approach 2:
The filter body transitions from a static internal component to a dynamic removable component. The twist-lock mechanism enables the filter body to be easily inserted and removed, providing user accessibility while maintaining a compact internal arrangement.
3Ease of repair
If a replaceable filter design is implemented, then filter maintenance is simplified, but additional space or instrument servicing is required
Solution Approach 1:
The filter system is segmented into modular components: the filter element housed in the filter body, which is separate from but insertable into the filter receptacle. This segmentation allows the filter to be replaced independently without affecting other system components.
Solution Approach 2:
The accessory receptacle is merged with the filter body into a single integrated component. This combination allows the accessory connector to be accessed while the filter is replaced, eliminating the need for additional external space while maintaining ease of maintenance.
