Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing product detection systems, particularly those using portable reading devices, face inefficiencies in verifying the completeness of products detected by customers, leading to potential malfunctions and customer inconvenience.
Innovation Solution
Incorporating an optical control detection unit that randomly samples products for verification, comparing identification data with those collected by the portable reading device to generate verification or correction signals, ensuring accurate and swift completion of the purchasing process without customer interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a portable reading device is used to detect products throughout the sales room, then the customer can detect products regardless of location, but the verification of product detection completeness becomes complex and time-consuming
Solution Approach 1:
The patent replaces complex mechanical verification processes with optical detection. The control detection device uses optical means (cameras, image sensors) to automatically detect and verify products, substituting manual verification and simplifying the overall system while maintaining comprehensive product detection coverage throughout the sales room
Solution Approach 2:
The patent introduces an intermediary control detection device that acts as a mediator between the portable reading device and the verification system. This device captures images or optical data of products and transmits them for verification, simplifying the interaction between components and reducing overall system complexity
2Reliability
If all detected products are verified for completeness, then identification reliability is high, but the verification process becomes time-consuming and reduces productivity
Solution Approach 1:
The patent applies partial verification by using the control detection device to randomly sample and verify a subset of products rather than checking every single item. This statistical sampling approach maintains sufficiently high identification reliability while dramatically reducing verification time and improving overall system productivity
Solution Approach 2:
The control detection device creates optical copies (images, digital representations) of products for verification purposes. Instead of physically handling or extensively examining each product, the system verifies product presence and accuracy through copied visual data, significantly accelerating the verification process while maintaining reliability
3Measurement precision
If an optical control detection device is introduced to verify products, then verification accuracy improves, but the device complexity increases
Solution Approach 1:
The control detection device is designed as a multi-functional unit that performs multiple tasks: optical detection of products, image capture, data transmission, and verification support. By consolidating these functions into a single device, the patent improves verification accuracy while minimizing the increase in overall system complexity compared to having separate dedicated components for each function
