Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing retail environments face high costs due to the infrastructure and maintenance requirements of electronic devices used to monitor customer activity and product movement, which are not efficiently managed.
Innovation Solution
A shopping cart deflection measurement system that uses sensors and a processing device to measure the deflection of the basket portion relative to a lower rack, allowing for real-time monitoring of customer activity and product fullness, thereby reducing management costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If electronic devices are deployed to monitor customer activity and product movement, then real-time monitoring capability is improved, but infrastructure cost and maintenance cost increase
Solution Approach 1:
The patent replaces complex electronic monitoring devices with a simple mechanical deflection measurement system. By measuring the physical deflection of the basket portion caused by product weight, the system achieves monitoring functionality without requiring sophisticated electronics, cameras, or sensors, thereby reducing infrastructure complexity while maintaining measurement capability
Solution Approach 2:
The invention uses simple, low-cost mechanical components (deflection sensors, spring mechanisms) instead of expensive electronic devices. These simple mechanical elements are inexpensive to manufacture and replace, reducing both initial infrastructure investment and ongoing maintenance costs while providing the necessary monitoring function
2Loss of information
If electronic devices are used to track customer activity, then data collection capability is improved, but data management complexity and cost increase
Solution Approach 1:
The patent extracts only the essential information needed for monitoring (basket fullness status) from the complex data collection process. By focusing solely on measuring whether the basket is full or empty through deflection, the system eliminates the need to manage complex customer data, purchase history, or movement tracking, thereby reducing data management complexity while still providing valuable retail insights
3Productivity
If traditional electronic monitoring systems are deployed, then customer activity tracking is improved, but overall management cost increases
Solution Approach 1:
The deflection measurement system is self-contained and automatically measures basket fullness without requiring external electronic infrastructure, manual intervention, or complex data processing. The mechanical system self-regulates and provides immediate feedback on basket status, maintaining operational efficiency while eliminating ongoing electronic device maintenance, software updates, and data management costs that burden traditional systems

Function Achieved in This Case
Enables real-time monitoring of customer activity and product fullness within retail environments with reduced management costs, improving operational efficiency and enabling accurate tracking of customer traffic and sales data.
Implementation Method 1
The basket portion can be pivotably mounted to the frame (e.g., in a cantilever manner) so as to enable deflection of at least one edge of the basket portion downward in the direction of gravity following a weight being placed in the basket portion
Data Source
AI summary
A shopping cart deflection measurement system and associated methods are described. The shopping cart deflection measurement system includes a shopping cart, a sensor, and a processing device equipped with a processor. The shopping cart includes a frame, a basket portion pivotably mounted to the frame so as to enable deflection of at least one edge of the basket portion downward in the direction of gravity following a weight being placed in the basket portion, and a lower rack portion mounted to the frame and disposed below the basket portion. The processing device can be configured to execute instructions to measure deflection of the basket portion relative to the lower rack portion of the shopping cart using data acquired by the sensor. The measured deflection can be indicative of a fullness of the basket portion with one or more products.
