Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing waterway connections in appliances are difficult to disconnect and reconnect, often leading to leaks due to secure seals that are hard to disassemble, or easy connections that fail to provide leak-proof integrity.
Innovation Solution
A quick-connect fitting system comprising a male and female fitting with a clip that allows for a leak-proof connection, featuring audible and tactile confirmation of secure attachment, and a mechanism for easy disassembly using a polymer clip with shape memory to snap into place and release.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If prior waterway connections were made securely to ensure leak-proof sealing, then connection reliability improved, but disassembly and reassembly difficulty increased
Solution Approach 1:
The connection system is divided into distinct components: a male fitting with protrusion, a female fitting with recess, and a separate clip assembly. This segmentation allows the connection to be made in discrete steps (insertion then clipping) and enables easy disassembly by removing the clip, resolving the contradiction between secure sealing and ease of disassembly.
Solution Approach 2:
The male and female fittings are pre-configured with complementary geometric features (protrusion and recess) that guide proper alignment and insertion before the final clipping step. This preliminary positioning ensures leak-proof sealing is achieved automatically during insertion, eliminating the need for difficult manual sealing operations during assembly.
2Ease of operation
If prior connections were made easily to facilitate disassembly, then ease of operation improved, but connection reliability deteriorated due to inadvertent loosening
Solution Approach 1:
The clip assembly provides dynamic control over the connection state. During normal operation, the clip maintains secure engagement preventing inadvertent loosening. For disassembly, the user can easily actuate the clip to release the connection. This dynamic mechanism resolves the contradiction between easy disassembly and connection reliability.
Solution Approach 2:
The clip acts as an intermediary element between the male and female fittings. It provides the locking function that ensures leak-proof connection while simultaneously serving as the release mechanism for easy disassembly. This intermediary component resolves the contradiction by mediating between the opposing requirements of security and ease of operation.
3Ease of operation
If consumer disassembly of prior connections was attempted, then accessibility improved, but proper reassembly failed leading to leaks
Solution Approach 1:
The connection system is designed to be self-guiding during assembly and disassembly. The geometric features (protrusion fitting into recess) and the clip mechanism provide tactile feedback and automatic alignment, enabling consumers to properly assemble and disassemble the connection without specialized tools or expertise, resolving the contradiction between consumer accessibility and proper reassembly.
Solution Approach 2:
The system provides tactile and audible feedback during assembly and disassembly operations. The snap-fit engagement of the protrusion into the recess and the clipping action give clear sensory confirmation of proper assembly, enabling consumers to achieve correct reassembly on their own, thus resolving the contradiction between ease of consumer disassembly and proper reassembly accuracy.
