Solution Overview

Problem

Battery-operated hand cleaning fluid dispensers in hospitals often become inoperative due to untimely battery changes and require frequent battery replacements, leading to substantial costs and inefficiencies, especially since some dispensers are used more frequently than others.

Innovation Solution

A solar-powered system that includes a rechargeable battery powered by a solar generator, with a remote electrically powered light source directing light onto the solar panel, and a control mechanism that wirelessly communicates with the dispenser to manage the light source's operation based on the battery's status, ensuring continuous power and reducing the need for frequent battery replacements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If battery operated dispensers are used in locations without hardwired electrical supply, then the dispensers can be placed in convenient locations such as middle of lobbies, but the dispensers frequently become inoperative due to batteries not being changed timely and require frequent battery replacements

Engineering Contradiction:
Improveplacement flexibilityVSAvoidcontinuous operation
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system enables self-powered operation through solar energy conversion. The solar panel on the dispenser converts ambient light into electrical energy to recharge the battery automatically, eliminating the need for manual battery replacement and ensuring continuous operation without human intervention.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system changes the energy source parameter from finite chemical energy (batteries) to renewable solar energy. By incorporating a solar panel that converts light energy into electrical energy, the system transforms the power supply mode from periodic replacement to continuous regeneration, resolving the reliability issue.

Inventive Principle:
Principle #35Parameter changes

2Use of energy by moving object

If remote electrically powered light sources are used to illuminate the solar panel, then energy generation can be optimized, but the system complexity increases with additional components and wiring

Engineering Contradiction:
Improveenergy generation efficiencyVSAvoidsystem structure
Core Design Contradiction:
Use of energy by moving objectVSDevice complexity

Solution Approach 1:

The light source serves dual functions: it provides illumination for the dispenser area and simultaneously powers the solar panel for energy generation. This multi-functionality eliminates the need for separate lighting and power generation systems, reducing overall system complexity while optimizing energy efficiency.

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

Solution Approach 2:

The system merges the lighting function and power generation function into a unified arrangement. The electrically powered light source is positioned to simultaneously illuminate the dispenser and direct light onto the solar panel, combining two functions into one integrated system that reduces complexity.

Inventive Principle:
Principle #5Merging (Combining)
