Bathroom Fixture Hose Assembly With Narrow-Groove Faucet Body
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bathroom fixtures face challenges in assembly due to fixed water outlet sizes colliding with bent pipe fittings, potential hose detachment, and insecure connections between hoses and valves, leading to metal contamination risks.
Innovation Solution
A flexible hose is integrated within the faucet body, secured by a narrow groove and plastic welding, with fasteners in the compression block to prevent detachment, allowing for easy assembly and metal-free materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a bent pipe fitting is inserted into the water outlet, then the hose can be connected to the faucet body, but the bent pipe fitting collides with the upper wall surface of the faucet body making assembly difficult
Solution Approach 1:
The patent extracts the hose connection from the traditional bent pipe fitting structure and integrates it directly into the faucet body through a hose fixing assembly. This eliminates the need for separate bent pipe fittings that collide with the faucet body wall, simplifying the assembly process while maintaining the hose connection function.
Solution Approach 2:
The hose fixing assembly is nested within the faucet body structure, with the hose passing through the faucet body and being secured by the fixing assembly. This nested arrangement allows the hose to be firmly fixed without requiring external bent pipe fittings, thereby avoiding collision with the faucet body wall and facilitating easier assembly.
2Ease of manufacture
If the hose is connected to the water aerator and inlet valve by insertion only, then the assembly is simple, but the hose may become detached during use
Solution Approach 1:
The patent applies preliminary action by pre-installing the hose fixing assembly within the faucet body before hose installation. This fixing assembly is prepared in advance to securely hold the hose, preventing detachment during use while maintaining simple assembly procedures. The fastening structure is predetermined and ready to secure the hose firmly.
Solution Approach 2:
The hose fixing assembly utilizes a curved or arc-shaped clamping structure that wraps around the hose, providing secure retention. This curved design allows the fixing assembly to firmly hold the hose in place, preventing detachment while maintaining ease of assembly. The arc-shaped structure conforms to the hose shape, ensuring reliable fixation.
3Strength
If the faucet body is made of lead-free copper or stainless steel, then the structural strength is sufficient, but metal ions may be released into the water posing health risks
Solution Approach 1:
The patent introduces an intermediary substance (such as a food-grade coating or lining) between the metal faucet body and the water. This intermediary layer prevents direct contact between water and metal surfaces, blocking the release of metal ions into the water while maintaining the structural strength of the metal faucet body. The coating acts as a barrier that eliminates health risks.
Solution Approach 2:
The patent employs composite material construction by combining metal faucet body with a non-metallic coating or lining layer. This composite structure maintains the mechanical strength and durability of metal while the outer coating layer prevents metal ion leaching into water. The combination of materials provides both structural integrity and safety.

AI summary
The easily assembled bathroom fixture includes a faucet body and a pipe fixing assembly, wherein an inlet valve of the pipe fixing assembly is equipped with a flexible hose. This flexible hose extends along the interior of the faucet body to an outlet portion, where the bottom surface features a water outlet. At the upper end of the water outlet, there is a narrow groove. Inserting a bent pipe fitting into the water outlet and passing through the narrow groove allows it to seamlessly integrate with the flexible hose, achieving convenient assembly.
