Solution Overview

Problem

Existing soap dispensers with illuminated positioning aids often require direct line-of-sight for effective hand positioning and lack versatility in material savings and low overall height designs, as well as clear status displays.

Innovation Solution

A dispenser with an outlet opening on the underside and an illuminated ring around the outlet on the edge of the housing, allowing oblique illumination and dual-color operation for status indication, enabling efficient hand positioning and service alerts.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the illuminated ring is positioned on the front edge of the dispenser housing, then hand positioning is facilitated from oblique angles, but the illumination may not be visible from the usual user position

Engineering Contradiction:
Improvehand positioningVSAvoidillumination visibility
Core Design Contradiction:
Ease of operationVSLoss of information

Solution Approach 1:

The illuminated ring is positioned on the front edge of the dispenser housing rather than on the top surface, changing the spatial dimension of illumination delivery. This edge positioning allows the light to be visible from oblique angles below and to the side, accommodating users who approach from different positions and angles, thereby resolving the contradiction between facilitating hand positioning and maintaining illumination visibility.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Volume of moving object

If the outlet opening is located on the underside of the dispenser housing, then material usage is optimized and overall height is reduced, but the illumination must be visible from multiple angles

Engineering Contradiction:
Improvematerial usageVSAvoidillumination visibility
Core Design Contradiction:
Volume of moving objectVSEase of operation

Solution Approach 1:

The outlet opening is positioned on the underside of the dispenser housing near the front edge, utilizing the vertical dimension efficiently. This placement reduces the overall height of the dispenser while optimizing material usage. The illuminated ring on the front edge complements this by providing visibility from oblique angles, ensuring users can locate the outlet despite its lower position.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The illuminated ring can be configured to change colors to provide different visual information, enhancing the visibility and communication of operational status. This color variation capability ensures that users can easily perceive the illumination and associated information from various angles, compensating for the unconventional outlet positioning.

Inventive Principle:
Principle #32Color changes

3Adaptability or versatility

If the illuminated ring serves multiple functions (hand positioning and status indication), then device versatility is improved, but the system complexity increases

Engineering Contradiction:
ImprovefunctionalityVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The illuminated ring is designed to perform multiple functions: guiding hand positioning during soap dispensing and indicating operational status through color changes. This multi-functionality is achieved by integrating the positioning and status indication capabilities into a single component, reducing the need for separate indicators and thereby managing complexity while enhancing versatility.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The illuminated ring utilizes color changes to convey different operational statuses (e.g., green for ready, red for low soap). This approach allows a single component to communicate multiple pieces of information visually, maintaining simplicity while achieving multi-functionality. The color-coded system provides intuitive feedback without requiring additional complex signaling mechanisms.

Inventive Principle:
Principle #32Color changes
