Compression Fitting Connector Assembly for Leak-Proof Converter Hoses
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing converter hoses face challenges in securely attaching a soft thermoplastic elastomer (TPE) connector to a more rigid hose without detachment, and they often collapse under typical water pressure, leading to leakage and inconsistent performance across various fixture sizes.
Innovation Solution
A connector assembly featuring a rigid compression fitting with a female cap, double-sided male component, and insert, which aligns with the elastomeric connector to form a seal, ensuring secure attachment and preventing collapse, while allowing for easy detachment and extension of the hose.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a soft TPE connector is attached to a rigid hose using existing methods, then the connector can be easily attached and detached, but the connection detaches under water pressure and the hose collapses
Solution Approach 1:
The connector assembly is divided into distinct functional segments: a compression fitting portion for secure attachment to the hose, and a TPE connector portion for easy fixture attachment. This segmentation allows each part to be optimized for its specific function while working together as a unified system that prevents detachment under pressure.
Solution Approach 2:
The assembly combines a rigid compression fitting (typically metal or hard plastic) with a soft TPE connector material. This composite construction leverages the strength and rigidity of the fitting to prevent hose collapse and detachment, while the TPE portion maintains ease of attachment and flexibility for various fixture sizes.
2Stability of the object's composition
If the hose is made more rigid to prevent collapse, then structural stability improves, but the connector becomes difficult to attach and detach
Solution Approach 1:
By separating the structural support function (compression fitting) from the attachment function (TPE connector), the design allows the fitting to provide rigidity for hose support while the flexible TPE portion maintains ease of attachment and adaptability to different fixture sizes.
Solution Approach 2:
Different parts of the assembly have different rigidity characteristics optimized for their specific functions: the compression fitting is rigid to prevent hose collapse, while the TPE connector is flexible to enable easy attachment and accommodation of various fixture dimensions.
3Reliability
If a secure connection mechanism is added to prevent detachment, then connection reliability improves, but device complexity increases
Solution Approach 1:
The compression fitting and TPE connector are merged into a single integrated assembly where the TPE connector is molded or attached to the fitting. This combination provides secure connection through the compression fitting's mechanical grip while maintaining relative simplicity by eliminating the need for separate attachment mechanisms.
Solution Approach 2:
The compression fitting is designed to self-grip the hose through its compression mechanism, automatically providing secure attachment without requiring additional fasteners, clips, or complex locking mechanisms. The TPE connector similarly self-adjusts to fit various fixture sizes through its flexibility.
4Adaptability or versatility
If the TPE connector is made softer to accommodate various fixture sizes, then adaptability improves, but the connector collapses under water pressure
Solution Approach 1:
The assembly separates the pressure support function (compression fitting) from the adaptability function (TPE connector). The rigid fitting provides structural strength to resist water pressure and prevent collapse, while the soft TPE portion maintains adaptability to various fixture sizes through its flexibility and elasticity.
Solution Approach 2:
The combination of rigid compression fitting material and soft TPE material creates a composite structure where each material contributes its optimal properties: the rigid portion provides pressure resistance while the TPE portion provides adaptability to different fixture dimensions.

AI summary
A connector assembly may include an elastomeric connector comprising an approximately perpendicular flange at a distal end thereof and an opening therethrough; and a rigid compression fitting having an opening aligned with the opening of the elastomeric connector. The connector assembly may be used with a converter hose. Related methods include attaching the converter hose to a shower head, faucet or spigot.
