Solution Overview

Problem

Beauticians face difficulties in shampooing and rinsing clients' heads, particularly in ensuring thorough saturation without the client having to lift their head, leading to discomfort and wet clothing due to water running down the neck and back.

Innovation Solution

A two-way spray system with a hand-held spray handle and a basin spray integrated into the shampoo basin, utilizing two operating levers to deliver water simultaneously to the front and back of the head, allowing for complete saturation without head movement, and featuring adjustable basin sprays for varying hair lengths.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If the beautician uses one hand to saturate the back of the head with water while rinsing, then the rinsing coverage is improved, but the beautician cannot properly control the hand-held spray handle nozzle

Engineering Contradiction:

Improvewater saturation coverageVSAvoidspray handle control

Core Design Contradiction:

Quantity of substanceVSEase of operation

Solution Approach 1:

The system divides the water delivery function into two separate spray outlets: a front spray for the beautician to hold and direct, and a basin spray integrated into the shampoo basin for automatic operation. This segmentation allows one hand to control the front spray while the other operates the basin spray lever, resolving the conflict between saturation coverage and handle control.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces a dual-lever control mechanism as an intermediary between the beautician's intent and the water delivery system. The top lever controls the front spray while the bottom lever controls the basin spray, allowing independent operation of each spray source and eliminating the need to juggle a single handheld nozzle with both hands.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Quantity of substance

If the client raises their head for rinsing the back, then the back of the head can be rinsed, but water runs down the neck and back wetting the clothing

Engineering Contradiction:

Improveback of head rinsingVSAvoidwater running down neck and back

Core Design Contradiction:

Quantity of substanceVSObject-affected harmful factors

Solution Approach 1:

The basin spray is positioned and directed to spray water upward and backward onto the client's head before the client needs to raise their head. This preliminary action wets the hair from the back, allowing the client to remain in a comfortable position with their head resting in the neck cradle, preventing water from running down the neck and back.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent changes the direction and dimension of water delivery by introducing the basin spray that shoots water upward and backward from the shampoo basin, rather than requiring the client to tilt their head back. This dimensional change in water delivery allows effective back-of-head rinsing while maintaining proper head position.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

3Productivity

If the beautician uses traditional single spray system, then the equipment complexity is low, but the productivity and efficiency of shampooing and rinsing is reduced

Engineering Contradiction:

Improveshampooing and rinsing efficiencyVSAvoidtwo way spray system

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent creates a multi-functional water delivery system where a single integrated setup provides both front spray (handheld) and basin spray (fixed) capabilities. The dual-lever mechanism allows the beautician to switch between or combine both spray modes within one system, increasing productivity without requiring multiple separate equipment sets.

Inventive Principle:

Principle #6Universality (Multi-functionality)

4Adaptability or versatility

If the basin spray is fixed in position, then the device complexity is reduced, but the adaptability to various hair lengths and client sizes is limited

Engineering Contradiction:

Improveadjustment for hair length and client sizeVSAvoidadjustable basin spray mechanism

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The basin spray is designed with adjustable components that allow the spray direction and intensity to be modified. This dynamic adjustment capability enables the fixed basin spray to adapt to different hair lengths, client sizes, and shampooing requirements, providing versatility comparable to movable systems while maintaining the simplicity of a fixed installation.

Inventive Principle:

AI summary

A two way spray system for shampooing and rinsing hair by saturating the entire head at once, or a section at a time with a redesigned spray handle with two control levers, and a adjustable basin spray. Inside the spray handle are three canals, a diverter canal situated between a intake canal and a outlet canal. The spray handle has a top lever that opens the intake canal sending water through the front nozzle, and a bottom lever that opens the diverter canal sending water into the outlet canal then to the basin spray in the shampoo basin. When operating both levers at once the entire head is saturated without the client having to lift or move their head. And while rinsing the back of the head the basin sprays adjustability for various length hair, children, and adults prevents water from running down their back wetting their cloths.
