Solution Overview

Problem

Current safety cabinet systems lack the capability to accurately track and correlate consumption values with user-specific data, leading to challenges in reliable budget planning, especially when multiple users access the same chemical, which can result in unclear cost allocation across different departments.

Innovation Solution

Implementing a method that uses sensor devices, such as weighing devices, to record consumption values and combine them with user-specific data, converting these values into payment values, which are then assigned to appropriate accounts for transparent and fair billing, utilizing a central control unit that communicates with multiple safety cabinets and can be integrated into a global network for data security.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple users access the same chemical in safety cabinets, then user access control and security monitoring are improved, but accurate cost allocation and budget planning become difficult

Engineering Contradiction:
Improvesecurity monitoringVSAvoidcost allocation clarity
Core Design Contradiction:
ReliabilityVSLoss of information

Solution Approach 1:

The system continuously monitors consumption values from safety cabinets and provides feedback to the control unit, which then correlates this data with user-specific data to generate payment values. This closed-loop feedback mechanism enables accurate tracking of who consumed what, resolving the contradiction between security monitoring and cost allocation clarity.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The control unit acts as an intermediary between the safety cabinet sensor devices and the billing system. It receives consumption data from the cabinets, correlates it with user-specific data, and generates payment values for billing. This intermediary function enables accurate cost allocation while maintaining security monitoring capabilities.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Measurement precision

If consumption values are tracked and correlated with user data, then accurate billing and budget planning are improved, but system complexity increases

Engineering Contradiction:
Improveconsumption tracking accuracyVSAvoidsystem structure
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The control unit performs multiple functions: it receives consumption data from safety cabinets, correlates this data with user-specific data, generates payment values, and assigns them to appropriate accounts. This multi-functional approach achieves accurate billing while avoiding the need for separate complex systems for each function.

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

Solution Approach 2:

The system merges the safety cabinet monitoring function with the billing and accounting functions into a single integrated control unit. By combining these functions, the system achieves accurate consumption tracking and billing without proportionally increasing overall system complexity.

Inventive Principle:
Principle #5Merging (Combining)

3Reliability

If sensor devices and control units are integrated into networks, then data security and accessibility are improved, but vulnerability to cyber threats increases

Engineering Contradiction:
Improvedata accessibilityVSAvoidcyber security vulnerability
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The control unit serves as a secure intermediary between the safety cabinet sensor devices and external networks. It processes and correlates data locally before transmitting to appropriate accounts, maintaining data security while enabling network accessibility. This intermediary approach allows the system to benefit from network connectivity without proportionally increasing vulnerability.

Inventive Principle:
Principle #24Intermediary (Mediator)
