Drinking Water Hose Adapter Locking Without Flow Restriction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hose arrangements for water supply systems face issues with reduced water flow and pressure due to connector-induced cross-sectional narrowing, and the use of metallic alloys is costly and requires complex processing, while plastic connectors often need individual adaptation for different geometries, limiting universal applicability.
Innovation Solution
A hose arrangement featuring an adapter with a form-fitting section and a separate locking part that secures the adapter to the hose without pressing, allowing for universal use across different connection geometries and maintaining optimal flow behavior, using high-performance plastics like polyphenylsulfone for durability and flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a connector is inserted into the hose end to create a positive connection, then the connection reliability is improved, but the flow cross-section is reduced and water pressure decreases
Solution Approach 1:
The patent introduces a receiver as an intermediary component that receives the hose end without requiring insertion of a connector into the hose. The receiver has a receiving space that accommodates the hose end, and the locking element locks the hose end in this space, thereby avoiding direct connector-hose insertion and preserving the flow cross-section while achieving reliable connection
Solution Approach 2:
The patent extracts the connector from the hose end by using a separate receiver that receives the hose end directly. The locking element is provided separately and locks the hose end in the receiver without being inserted into the hose, thereby removing the problematic connector component that caused flow cross-section reduction
2Strength
If metallic alloys are used for the connector, then the strength and durability are improved, but the raw material cost increases and manufacturing complexity increases
Solution Approach 1:
The patent changes the material parameter from metallic alloy to plastic for both the receiver and locking element. This material substitution maintains sufficient strength while dramatically reducing raw material cost and eliminating complex material removal processes, making the manufacturing much simpler and more cost-effective
3Ease of manufacture
If plastic material is used for the connector, then the manufacturing cost is reduced, but the connector needs to be individually adapted for different connection geometries
Solution Approach 1:
The patent makes the hose end itself universal by providing it with a standardized locking section that can be received by different receivers. The hose end can be locked in various receivers with different connection geometries through the standardized locking mechanism, eliminating the need to produce different hose types for different geometries
4Stability of the object's composition
If the hose is crimped onto the connector, then the connection stability is improved, but the hose cross-section is permanently narrowed and flow rate is reduced
Solution Approach 1:
The patent introduces the receiver as an intermediary that receives the hose end without crimping. The locking element provides connection stability by locking the hose end in the receiver, while the hose end itself remains unc crimped and maintains its full flow cross-section
Solution Approach 2:
The patent removes the crimping process entirely by using a locking mechanism that secures the hose end in the receiver without applying radial compression to the hose. This extraction of the crimping step preserves the hose cross-section and maintains optimal water flow rate
