RFID Sales Compartment Partition for Public Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Public transport vehicles with self-service sales compartments face challenges in reducing passenger dwell time and minimizing theft risks due to lack of supervision, leading to disorganization and increased transaction times.
Innovation Solution
A sales compartment design with a longitudinal partition separating two passages, incorporating radiofrequency identification (RFID) tags on items and a detection device that emits signals to control access and deter theft, along with strategically placed vending machines to manage passenger flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If self-service sales compartment is implemented, then number of sales operations increases, but risk of theft increases
Solution Approach 1:
The patent implements self-service sales compartment where passengers can independently select and purchase items using automated vending machines and payment devices, eliminating the need for vendor intervention and enabling multiple simultaneous sales operations
Solution Approach 2:
The patent employs RFID detection devices that provide real-time feedback on item location and status, allowing the system to track items throughout the sales area and detect when items are removed from designated areas, enabling automated theft prevention
2Productivity
If self-service sales compartment is implemented, then number of sales operations increases, but disorganization increases
Solution Approach 1:
The patent divides the sales compartment into multiple zones (selection area, payment area, exit passage) separated by partitions, creating structured pathways that guide passenger flow and prevent random movement while maintaining self-service functionality
Solution Approach 2:
The patent introduces detection devices as intermediaries between passengers and items, using RFID technology to automatically identify items and track passenger interactions, thereby organizing the self-service process and preventing disorganization
3Object-affected harmful factors
If partition with detection device is installed, then theft detection improves, but device complexity increases
Solution Approach 1:
The patent designs the partition structure to serve multiple functions: it physically separates zones to guide passenger flow, incorporates RFID detection devices for theft prevention, and integrates with the vending machine system for coordinated control, thereby reducing overall system complexity through multi-functionality
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
This design reduces passenger dwell time by directing circulation and effectively detects potential thefts, enhancing operational efficiency and security within the limited space of public transport vehicles.

AI summary
The invention relates to a vehicle (10) comprising a compartment (15) including a sales area (25), an access area (30), and an intermediate area (35) between the sales area (25) and the access area (30). The sales area (25) includes a set of display stands (40) designed to hold items bearing a label capable of receiving a first radio frequency signal and emitting a second radio frequency signal in response. The intermediate area (35) includes a partition (55). The intermediate area (35) includes a first passage (45) and a second passage (50) offset along a transverse direction (Y) of the compartment (15) and connecting the access area (30) to the sales area (25). The partition (55) separates the first passage (45) from the second passage (50) and includes a device (75) configured to emit the first signal and to trigger the transmission of a signal to a user when the user receives the second signal.
