Solution Overview

Problem

Traditional soap shakers are ineffective for dispensing solid detergent bars, leading to oversupply, premature dissolving, and inefficiency due to their abrasive nature and open structure, which is not suitable for concentrated detergent bars.

Innovation Solution

A dispenser system comprising a container with a lid and tray, featuring controlled apertures and fins to manage fluid flow, allowing for precise detergent dispensing and drying, using a solid detergent bar with surfactants.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a traditional soap shaker with wide open mesh is used to dispense solid detergent bar, then the shaker can effectively dispense traditional dish soap, but the detergent bar undergoes premature disintegration due to excessive abrasion and water flow

Engineering Contradiction:
Improvedispensing effectivenessVSAvoiddetergent bar stability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent applies local quality by providing a dispenser with a controlled aperture structure that offers different characteristics at different locations. The aperture allows water to flow through in a controlled manner, providing sufficient water contact for detergent activation while preventing excessive abrasion that would cause premature disintegration. This localized control of water flow quality resolves the contradiction between effective dispensing and bar stability.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent changes the physical parameters of the dispensing system by replacing the wide open mesh structure with a controlled aperture in a solid dispenser body. This parameter change transforms the water flow from uncontrolled and abrasive to regulated and gentle, allowing effective detergent dispensing while maintaining detergent bar integrity during use.

Inventive Principle:
Principle #35Parameter changes

2Productivity

If a traditional soap shaker with wide open mesh is used, then the shaker allows free water flow for washing, but excessive water runs directly over the soap bar causing premature dissolving

Engineering Contradiction:
Improvewashing efficiencyVSAvoiddetergent waste
Core Design Contradiction:
ProductivityVSLoss of substance

Solution Approach 1:

The patent introduces an intermediary structure - the controlled aperture in the dispenser body - that mediates between the water flow and the detergent bar. This intermediary controls the rate and manner of water contact, allowing sufficient water to reach the detergent for effective washing while preventing excessive water from causing premature dissolving and waste.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The dispenser provides local quality control by concentrating water flow through a specific controlled aperture rather than allowing diffuse flow across the entire bar surface. This localized water contact enables effective detergent activation while minimizing overall water exposure and preventing excessive dissolving.

Inventive Principle:
Principle #3Local quality

3Loss of energy

If a concentrated detergent bar is used to reduce plastic bottle usage, then sustainability is improved, but the softer texture requires a non-abrasive dispenser to prevent premature dissolving

Engineering Contradiction:
Improveenvironmental sustainabilityVSAvoiddetergent bar durability
Core Design Contradiction:
Loss of energyVSReliability

Solution Approach 1:

The patent changes the physical parameters of the dispensing system from an abrasive mesh structure to a solid body with a controlled aperture. This parameter change creates a non-abrasive environment that preserves the integrity of softer concentrated detergent bars, enabling their use for sustainability purposes without premature dissolving and waste.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent converts the potential harm of using softer detergent bars (premature dissolving) into a benefit by designing a dispenser that specifically protects the bar while still allowing effective detergent release. The controlled aperture prevents excessive abrasion that would waste the bar, thereby supporting the sustainability goal of using concentrated bars instead of plastic bottles.

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)
