Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a cart robot that can autonomously navigate and park itself in movement restricted areas, such as those found in supermarkets or airports, while preventing theft by using radio frequency gates and efficiently managing space by reducing complexity.
Innovation Solution
A cart robot equipped with a positioning sensor, movement unit, and controller that receives signals from a transmission module to determine entry into a movement restricted area, park around it, and enter a security mode to prevent unauthorized operation, utilizing camera sensors and artificial intelligence for area identification and monitoring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the cart robot autonomously follows the user in large spaces, then user convenience is improved, but the cart robot may enter movement restricted areas causing operational conflicts
Solution Approach 1:
The cart robot proactively queries about movement restricted areas before entering them, and the transmission module proactively transmits location information when the user enters such areas. This preliminary action prevents operational conflicts by establishing awareness and coordination before the robot attempts to follow the user into restricted zones.
Solution Approach 2:
The system implements a feedback mechanism where the transmission module detects when the user enters a movement restricted area and transmits this location information to the cart robot. The robot then receives this feedback and adjusts its following behavior accordingly, stopping or modifying its path to avoid entering the restricted area, thus maintaining operational reliability while preserving user convenience.
2Measurement precision
If the cart robot enters movement restricted areas to follow the user, then tracking accuracy is improved, but security and theft prevention are compromised
Solution Approach 1:
The transmission module performs preliminary detection of movement restricted areas (such as security zones with RF gates) and transmits location information to the cart robot before the robot enters these areas. This allows the robot to anticipate and avoid restricted zones, maintaining tracking accuracy within permitted areas while preventing security breaches.
Solution Approach 2:
The transmission module acts as an intermediary between the user and the cart robot in restricted areas. It detects the user's location and communicates this information to the robot, enabling the robot to track the user's movements and intentions without physically entering security restricted zones, thus balancing tracking accuracy with security requirements.
3Adaptability or versatility
If the cart robot operates in all areas including restricted zones, then service coverage is improved, but space complexity and control difficulty increase
Solution Approach 1:
The system segments the operating space into accessible areas and movement restricted areas. The cart robot operates autonomously in accessible areas with full service coverage, while in restricted areas, it receives location information from the transmission module and adjusts its behavior accordingly. This segmentation maintains versatility in open spaces while reducing complexity in restricted zones by eliminating the need for direct navigation and control in those areas.
