Vehicle Movement Sensor Tag Feedback System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle systems fail to adequately limit movement during passenger boarding or disembarking, particularly on sloped or slippery terrain, leading to potential injuries due to insufficient brake application feedback.
Innovation Solution
A vehicle movement sensor system comprising an axially rotating member connected to the wheels, a tag attached to this member, and a sensor that detects the tag's movement, sending feedback to the operator through a computer, providing alerts and feedback mechanisms to ensure the vehicle remains stationary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vehicle brake is applied to limit movement, then the possibility of unintended consequences is reduced, but the operator cannot know if the brake is sufficient when terrain is sloped or slippery
Solution Approach 1:
The patent implements a feedback mechanism where a sensor detects the position of a tag attached to the axially rotating member, and this information is fed back to the operator through visual or audible signals. This allows the operator to know whether the vehicle has moved despite brake application, enabling corrective action if necessary.
2Ease of operation
If no movement detection system is used, then the device complexity is low, but the operator cannot detect vehicle movement during passenger boarding or disembarking
Solution Approach 1:
The patent uses a tag as an intermediary object attached to the axially rotating member. The tag itself does not contain sensors or power sources but serves as a passive marker that reflects or emits signals to the sensor, simplifying the overall system while enabling movement detection.
3Force
If the vehicle brake is applied, then movement is limited, but insufficient brake application on sloped or slippery terrain allows vehicle movement
Solution Approach 1:
The system provides preliminary warning to the operator before unsafe movement occurs. By detecting even small movements through the tag-sensor mechanism, the operator is alerted in advance and can take corrective action to apply additional brake force or secure the vehicle more firmly.

AI summary
A vehicle comprises at least one wheel supporting the vehicle and an engine. At least one axially rotating member operatively connects the engine with the wheel such that the wheel moves responsive to operation of the engine. At least one tag is disposed on the axially rotating member. At least one sensor is disposed on the vehicle so that the sensor can detect movement of the tag. A computer disposed on the vehicle is operatively connected with the sensor. The sensor sends a signal to the computer when the sensor detects movement of the tag. Means on the vehicle provides an operator of the vehicle with feedback indicative of movement of the vehicle.
