Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing connection structures for filter housings to support structures are cumbersome and require precise tilting, making them difficult to connect reliably and efficiently, especially for applications requiring high purity water in laboratory settings.
Innovation Solution
A connection structure featuring guide members on the filter housing cover and support structure that allow for a linear movement, preventing tilting and ensuring accurate alignment, along with latching mechanisms that provide increased resistance for secure engagement, enabling easy and reliable connection with one-hand operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the filter housing cover is connected using traditional support arms with cutouts and locking lugs, then the connection provides structural support, but the connection process requires precise tilting and is difficult to operate
Solution Approach 1:
The connection structure is divided into separate functional elements: guide members on the support structure, corresponding guide elements on the filter housing cover, separate connection elements for fluid exchange, and distinct locking mechanisms. This segmentation allows each component to perform its specific function independently, simplifying the overall connection process while maintaining structural integrity.
Solution Approach 2:
Guide members and guide elements act as intermediary components that facilitate the connection process. These guide elements precede the main connection elements, providing alignment and directional guidance that enables users to connect the filter housing cover without requiring precise tilting or complex positioning maneuvers.
2Reliability
If the connection structure uses locking lugs in cutouts requiring tilted positioning, then the connection can be secured, but the operation becomes difficult especially for users with smaller hands
Solution Approach 1:
The connection structure incorporates self-aligning features where the guide members and guide elements automatically orient the filter housing cover into the correct position during insertion. This self-service mechanism eliminates the need for users to manually tilt or precisely position the housing, making the connection reliable and accessible to users with varying hand sizes and strengths.
Solution Approach 2:
The connection elements are designed with modified geometric parameters, including enlarged operating surfaces and extended lever arms, that reduce the force and dexterity requirements for users. The guide elements provide mechanical advantage that transforms small user inputs into reliable locking actions, maintaining connection security while improving ease of operation.
3Manufacturing precision
If the lid side surfaces must be precisely fitted into the area between locking lugs and angled upper surface, then the connection can engage, but the process requires exact tilted position holding
Solution Approach 1:
The guide members and guide elements perform the preliminary alignment action before the main connection elements engage. By providing pre-alignment guidance during the insertion process, these elements eliminate the need for users to hold the lid in a precise tilted position, as the guide structure automatically establishes the correct orientation as the filter housing cover is inserted.
4Productivity
If traditional connection structures are used, then fluid exchange can be provided, but accidental disconnection may occur
Solution Approach 1:
The connection structure merges multiple functions into integrated components: the guide members simultaneously provide alignment guidance and structural support, while the connection elements combine fluid passage formation with mechanical interlocking. This merging ensures that fluid exchange efficiency is maintained while connection stability is enhanced through unified design.
