Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems fail to accurately detect and account for the tilt, lean, or rotation of a user, rider, or payload, particularly in vehicles, which can impact stability and control, as existing technologies do not effectively measure changes in the center of mass relevant to these movements.
Innovation Solution
An apparatus utilizing a combination of sensors, including weight, force, and electromagnetic sensors, strategically positioned to detect and measure changes in tilt, lean, rotation, and movement of a user, rider, or payload, determining the center of mass and its changes, and using computational devices to process this data for control algorithms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If sensors are used to detect tilt, lean, or rotation of a user, rider, or payload, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The system divides the detection function into multiple specialized sensors (weight sensors, force sensors, electromagnetic sensors) positioned at different locations. Each sensor type detects specific physical quantities, and their results are combined to achieve comprehensive detection of tilt, lean, and rotation with high precision while maintaining modular complexity management.
Solution Approach 2:
The sensor system is designed to perform multiple detection functions simultaneously - detecting weight, force, electromagnetic fields, tilt, lean, and rotation using a coordinated array of sensors. This multi-functional approach consolidates what would otherwise require separate detection systems, improving measurement precision without proportionally increasing device complexity.
2Measurement precision
If multiple sensors are positioned to detect changes in center of mass, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The center of mass detection is segmented into multiple measurement points using distributed weight sensors and force sensors. By measuring forces at multiple locations and calculating the centroid mathematically, the system achieves precise center of mass detection while distributing sensor complexity across multiple simple, identical sensor units rather than requiring complex single-point sensors.
Solution Approach 2:
The system introduces computational algorithms as an intermediary between the raw sensor data and the final center of mass determination. The computational device processes force vectors from multiple sensors, applies mathematical calculations to determine center of mass position, and provides this information to control systems, thereby simplifying the physical sensor arrangement while maintaining high measurement precision.
3Stability of the object's composition
If the system continuously monitors and responds to position changes, then stability and control are improved, but use of energy increases
Solution Approach 1:
The continuous monitoring system operates using periodic sampling of sensor data rather than truly continuous measurement. The computational device processes sensor inputs at defined intervals, determining changes in center of mass and triggering control responses only when thresholds are exceeded. This periodic operation maintains vehicle stability while significantly reducing energy consumption compared to truly continuous monitoring.
Solution Approach 2:
The system implements feedback control where sensor detections of tilt, lean, and rotation are continuously fed back to control algorithms. The control system adjusts vehicle operations in response to detected changes, creating a closed-loop system that maintains stability. The feedback mechanism is designed to activate control actions only when necessary, balancing stability requirements with energy conservation by avoiding unnecessary continuous adjustments.
