Solution Overview

Problem

Existing faucets with detachable spray heads often have complex mechanisms that lead to increased wear and difficulty in attachment/detachment, and lack a sleek, modern design, especially in bathroom applications where space is limited and hose storage is not available.

Innovation Solution

A faucet design featuring a fixed support arm and an exposed flexible hose with a fixed length, where the spray head is releasably coupled to the faucet body via a bracket with a recess, allowing for easy detachment and reattachment while maintaining a modern aesthetic and reducing wear through resilient material properties.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a detachable spray head with extension support arm is used, then the spray head position is adjustable and reachability is improved, but the device complexity increases and attachment/detachment becomes difficult

Engineering Contradiction:

Improvespray head position adjustabilityVSAvoidnumber of moving parts

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The spray head system is segmented into a detachable spray head component and a faucet body with bracket, allowing independent functionality while simplifying the connection mechanism. The spray head can be separated from the complex support arm assembly, reducing overall system complexity while maintaining position adjustability through simple bracket engagement.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The spray head is extracted as a separate detachable component from the faucet body, allowing it to be removed and repositioned independently. This extraction eliminates the need for complex integrated support mechanisms while maintaining the ability to adjust spray head position by simply reattaching to the bracket.

Inventive Principle:

Principle #2Taking out (Extraction)

2Adaptability or versatility

If a pull out hose with spring support is used, then the spray head can be moved relative to the basin, but the hose requires storage space below the mounting surface

Engineering Contradiction:

Improvespray head mobilityVSAvoidstorage space below mounting surface

Core Design Contradiction:

Adaptability or versatilityVSVolume of stationary object

Solution Approach 1:

The hose and spring support mechanism are extracted and replaced with a flexible hose directly connected to the faucet body. This eliminates the need for storage space below the mounting surface while maintaining spray head mobility through the flexible hose connection.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

A flexible hose is used instead of a rigid pull-out hose with spring support. The flexible hose provides the necessary mobility and curvature to allow spray head movement while eliminating the need for a storage compartment, as the hose can be positioned and secured without retraction mechanisms.

Inventive Principle:

Principle #30Flexible shells and thin films

3Adaptability or versatility

If multiple moving parts are used for spray head attachment, then the spray head can be detached and repositioned, but the components experience increased wear

Engineering Contradiction:

Improvespray head repositionabilityVSAvoidcomponent wear

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The attachment mechanism is segmented into simple engagement surfaces: a bracket on the faucet body and a corresponding recess on the spray head. This segmentation reduces the number of moving parts and contact points, thereby reducing wear while maintaining the ability to detach and reposition the spray head.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The complex mechanical attachment system with multiple moving parts is replaced with a simple geometric interlocking mechanism using the bracket and recess. This substitution eliminates complex joints, pins, and fasteners that would experience wear, while still allowing easy detachment and repositioning through simple alignment and engagement.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The design simplifies attachment and detachment, reduces wear, and provides a modern aesthetic by using a flexible hose that maintains a curved shape when attached, enabling easy maneuverability and efficient use in limited spaces without the need for additional storage.

Implementation Method 1

the flexible hose has a fixed length between the faucet body and the spray head... the flexible hose allows the spray head to be moved by a user to a position remote from the faucet body while resiliently returning to the curved shape when the spray head is coupled to the faucet body

Methodology Applied

Scientific EffectElastic memory: Elasticity

AI summary

A faucet includes a faucet body having a base, a support arm cantilevered from the base, and a bracket formed on a free end of the support arm. A flexible hose has one end coupled to the faucet body. A spray head is coupled to the other end of the flexible hose such that the flexible hose has a fixed length between the faucet body and the spray head. The spray head has an outer surface with a recess formed therein and is configured to receive the bracket such that the spray head is releasably coupled to the faucet body.
