Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for managing small goods stores, such as stock monitoring and replenishment, rely heavily on manual processes and are prone to errors, with automatic systems being expensive and inflexible, especially for varying and lightweight items.
Innovation Solution
A system utilizing RFID transponders on storage units for remote identification, an active return station with a reading device for automatic registration, and information transmission to responsible personnel, allowing for automatic consumption monitoring and inventory supplementation without the need for manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual inspection and visual verification are used for stock monitoring, then the system is simple and flexible, but it is prone to errors and relies on personal experience
Solution Approach 1:
The storage units automatically report their own status (full or empty) through RFID transponders without requiring manual inspection. The system serves itself by automatically detecting when storage units need replenishment and transmitting this information to responsible personnel, eliminating the need for manual visual verification while maintaining high accuracy.
Solution Approach 2:
The patent replaces manual mechanical inspection with an automated RFID-based detection system. RFID transponders on storage units communicate their status electronically to a reading device, substituting the manual visual inspection process with an automated electromagnetic field-based system that provides reliable and error-free stock monitoring.
2Extent of automation
If automatic weight check systems are used for monitoring consumption, then automation is improved, but the system becomes expensive and inflexible for different goods types
Solution Approach 1:
The RFID-based system provides universal applicability across different types of storage units and goods. The same RFID transponder and reading device can monitor various storage locations and container types, making the system flexible and adaptable to different goods types without requiring specialized weight check equipment for each scenario.
Solution Approach 2:
Instead of using complex weight sensing mechanisms, the patent uses RFID transponders that create an electronic copy or representation of the storage unit's status. This digital copying approach replaces physical weight measurement systems, reducing hardware complexity and cost while maintaining automation capabilities.
3Extent of automation
If weight-based automatic systems are used, then automation is achieved, but precision is insufficient for small and light goods
Solution Approach 1:
The patent replaces mechanical weight-based detection with electromagnetic field-based RFID detection. This substitution eliminates the precision limitations of weight sensors for lightweight items, as RFID technology detects the presence and status of storage units through electromagnetic fields rather than mechanical weight measurement, providing accurate monitoring regardless of goods weight.
4Adaptability or versatility
If manual restocking is used, then flexibility is maintained, but productivity is low and significant time is required
Solution Approach 1:
The system implements continuous feedback through RFID transponders that automatically report storage unit status to responsible personnel. This feedback mechanism enables rapid response to replenishment needs, significantly improving productivity compared to manual inspection cycles, while the system remains flexible in handling different storage configurations and goods types.
