Collision Judgment System for Moving Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing collision detection systems in remote control devices, such as intelligent battle toy cars, cannot accurately determine whether a collision is with another moving device or an obstacle, and have a significant blind area due to scattered sensors.
Innovation Solution
A collision judgment system that uses acceleration sensors to collect data, determines collisions, and sends collision information with a moving device identifier and time to a control device, which then forwards it to a collision judgment device. The system detects if multiple devices report collisions within a predetermined time interval and with similar times to determine if moving devices are colliding with each other.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If scattered sensors are used on the moving device to detect collision, then the moving device can detect collision signals, but a relatively large collision detection blind area exists
Solution Approach 1:
The patent introduces a collision judgment device as an intermediary that receives collision information from multiple moving devices and determines whether they collided with each other. This mediator coordinates the detection efforts of scattered sensors across multiple devices, effectively reducing the overall blind area by pooling detection coverage from multiple sources rather than relying on each individual device's limited sensor array.
2Reliability
If a moving device uses collision signals to determine collision occurrence, then it can detect whether collision happens, but it cannot determine whether a collision object is a moving device or an obstacle
Solution Approach 1:
The patent implements a feedback mechanism where collision information including collision time is sent from moving devices to a collision judgment device. The judgment device analyzes timing information from multiple sources to determine whether collisions occurred between moving devices or with obstacles. This feedback loop enables the system to infer collision object identity based on the temporal patterns and coordination of collision signals from multiple devices.
Solution Approach 2:
The collision judgment device serves as an intermediary that processes collision information from multiple moving devices. By receiving and analyzing collision data from multiple sources, it can distinguish between collisions with other moving devices (which would generate coordinated collision signals from both devices) and collisions with obstacles (which would generate signals from only one device).
