Solution Overview

Problem

Small and confined spaces, such as food delivery boxes, are difficult to clean and sanitize consistently due to the lack of mechanisms ensuring uniform coverage and objective record-keeping in manual processes.

Innovation Solution

A portable, battery-powered hygiene system with a spray nozzle and control circuit that automatically conducts cleaning and sanitization cycles, ensuring uniform distribution of hygiene agents and records performance data for transmission to an analysis center.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual cleaning and sanitization is performed by spraying chemical agents, then the process can be completed, but the quality and thoroughness are inconsistent and depend on the person performing the procedure

Engineering Contradiction:
Improveconsistency of cleaning qualityVSAvoidmanual operation complexity
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The system performs cleaning and sanitization automatically without human intervention. The control circuit activates the pump to spray hygiene agents through nozzles, and the system self-monitors the process via sensors, eliminating dependence on human operators for consistent quality

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

Sensors detect the presence and distribution of hygiene agents during the cleaning process, providing feedback to the control circuit. This closed-loop system ensures consistent application of chemical agents and maintains reliable cleaning quality through automated monitoring and adjustment

Inventive Principle:
Principle #23Feedback

2Reliability

If a two-step cleaning and sanitizing procedure is used, then thorough hygiene is achieved, but each cycle becomes more complicated and less consistent

Engineering Contradiction:
Improvehygiene procedure consistencyVSAvoidcleaning cycle complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system combines cleaning and sanitizing functions into a single integrated cycle. The control circuit manages both processes sequentially or simultaneously through one unified operation, reducing procedural complexity while maintaining thorough hygiene through automated multi-stage treatment

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The system performs cleaning and sanitizing in continuous automated cycles without interruption. The pump and nozzle system continuously applies hygiene agents, and the monitoring system continuously tracks performance, ensuring consistent results through uninterrupted automated operation

Inventive Principle:
Principle #20Continuity of useful action

3Loss of information

If manual cleaning procedures are used, then flexibility is maintained, but no objective record is provided showing that hygiene procedures are routinely followed

Engineering Contradiction:
Improvehygiene record-keepingVSAvoidautomation level
Core Design Contradiction:
Loss of informationVSExtent of automation

Solution Approach 1:

Sensors and monitoring circuits continuously detect and record hygiene process parameters such as chemical agent concentration, spray duration, and coverage areas. This objective data is stored and can be retrieved to verify routine compliance with hygiene procedures

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system replaces manual record-keeping with automated electronic monitoring and data storage. Sensors substitute for human observation, and digital records substitute for manual logs, providing objective, tamper-resistant evidence of hygiene procedure compliance

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
