Solution Overview
Problem
Existing shopping cart systems lack reliable electronic components for data detection and evaluation, leading to errors and faulty evaluations, particularly as data is increasingly moved to the cloud, compromising the safety and efficiency of inventory management and theft prevention.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If electronic components are added to shopping carts for data detection, then data detection capability is improved, but system reliability deteriorates due to errors and failures in cloud-based data evaluation
Solution Approach 1:
The patent introduces an intermediate evaluation system that operates locally (in the online shop's own infrastructure) between the electronic components in shopping carts and the cloud servers. This intermediary layer processes and validates data locally before cloud transmission, preventing cloud errors from directly affecting system reliability while maintaining electronic data detection capabilities.
Solution Approach 2:
The system implements preliminary validation and error checking mechanisms that cushion against potential cloud-based evaluation failures. By pre-processing data and establishing validation rules before data leaves the local system, the patent creates a protective buffer that maintains reliability even when cloud-based evaluation encounters errors.
2Productivity
If data is relocated to the cloud for evaluation, then processing capability is improved, but system safety deteriorates due to errors and failures in cloud-based evaluation
Solution Approach 1:
The patent segments the data evaluation process into multiple independent stages: local data collection by electronic components, intermediate validation in the online shop's infrastructure, and final cloud-based processing. This segmentation allows the system to leverage cloud processing power while isolating safety-critical validation steps from potential cloud errors.
Solution Approach 2:
The system implements feedback mechanisms where evaluation results from the cloud are validated against local reference data and validation rules. If cloud-based evaluation produces inconsistent or erroneous results, the feedback loop triggers re-evaluation or alerts system operators, maintaining safety despite cloud processing.
3Measurement precision
If multiple electronic components are deployed in shopping carts and infrastructure, then data detection and tracking capability is improved, but device complexity increases
Solution Approach 1:
The patent designs electronic components with multi-functionality to reduce overall system complexity. For example, the electronic components in shopping carts serve multiple purposes: tracking cart location, identifying the customer, and monitoring shopping behavior. This universal approach reduces the number of separate components needed while maintaining high measurement precision.
Solution Approach 2:
The system merges previously separate functions into integrated components. For instance, the evaluation system combines data collection, validation, and processing functions into a unified infrastructure that operates across online and offline channels, reducing complexity compared to having separate systems for each function.
