Point of Sale Security Monitor Using Weight Sensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing point of sale checkout devices lack space for personal items, leading to potential theft and distraction from the transaction process, as consumers must hold or leave these items unattended.
Innovation Solution
A security monitor system integrated into the checkout device that uses a weight sensor to detect personal items and activates an alarm if they are removed during or after the transaction, ensuring their presence and security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If flat space at the checkout device is used for functional items, then the checkout function is complete, but there is no space for personal items
Solution Approach 1:
The patent introduces a vertical dimension by mounting the security monitor and personal item holding area above the checkout counter surface. This allows personal items to be held in the vertical space above the counter, separate from the horizontal workspace for functional items, thereby resolving the space conflict without reducing either function's effectiveness.
2Reliability
If personal items are held during self-checkout, then security is improved, but the shopper is distracted from the transaction
Solution Approach 1:
The security monitor acts as an intermediary device that automatically monitors personal items without requiring the shopper's direct attention or intervention. The system detects when personal items are placed on the counter and provides alerts if they are removed, securing items while allowing the shopper to focus on the transaction.
Solution Approach 2:
The security monitoring system operates autonomously, automatically detecting the presence and removal of personal items without requiring the shopper to manually monitor or report their location. The system self-manages security concerns, reducing the shopper's cognitive load and distraction.
3Area of stationary object
If personal items are left in the carriage, then space is available for functional items, but theft becomes possible
Solution Approach 1:
The security monitor provides real-time feedback about personal items through visual and audible alerts when items are placed on the counter or removed. This feedback mechanism creates a monitored environment that discourages theft while maintaining workspace availability, as the system actively detects and notifies about item movements.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively monitors and secures personal items during the transaction, preventing theft and reminding shoppers of their belongings after the process is complete, thus enhancing security and focus on the transaction.
Implementation Method 1
sensing a signal of a weight sensor indicative of a weight of the personal items belonging to the shopper placed upon an interface of a security monitor
Data Source
AI summary
A method of confirming security of personal items belonging to a shopper during a point of sale transaction is disclosed. The method includes sensing a signal of a weight sensor indicative of a weight of the personal items placed upon an interface of a security monitor of a point of sale checkout device. The method further includes activating an alarm in response to sensing a change in the signal of the weight sensor that is indicative of a removal of the personal items during the point of sale transaction. The method also includes activating the alarm in response to sensing a continued state of the signal of the weight sensor following the point of sale transaction.
