Satellite Signal Receiver Positioning on Motorcycle Fender
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data acquisition units in vehicles, particularly single-track vehicles like motorcycles and bicycles, face issues with satellite signal shadowing due to suboptimal arrangement of satellite signal receivers, leading to interference and inaccurate position determination.
Innovation Solution
The satellite signal receiver is positioned on the upper side of the fender in front of the front wheel fork, preferably centrally, and is designed as a separate component from the storage unit, allowing for optimal exposure to satellite signals and protection from external influences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the satellite signal receiver is positioned on the vehicle, then data acquisition is enabled, but satellite signal shadowing occurs due to vehicle components and driver position
Solution Approach 1:
The patent transitions the satellite signal receiver from ground-based infrastructure to an aerial platform (drone), moving the measurement system to a different spatial dimension above the vehicle. This dimensional change eliminates shadowing by vehicle components and driver, as the receiver operates from an elevated position where line-of-sight to satellites is unobstructed.
2Reliability
If the satellite signal receiver is positioned to maximize sky exposure, then signal reception improves, but the receiver becomes vulnerable to external influences and damage
Solution Approach 1:
The system segments the positioning function from the vehicle platform, placing the satellite signal receiver on a separate aerial platform (drone) rather than mounting it directly on the vehicle. This segmentation allows the receiver to maintain optimal sky exposure while being protected from vehicle-related hazards through the protective housing and independent mounting structure.
Solution Approach 2:
The aerial platform (drone) acts as an intermediary carrier between the vehicle and the satellite signal receiver. It provides a stable, protected mounting environment with appropriate housing that shields the receiver from external influences while maintaining the necessary orientation for signal acquisition.
3Device complexity
If the satellite signal receiver is integrated with the storage unit, then device complexity is reduced, but flexibility in optimal positioning is limited
Solution Approach 1:
The system separates the satellite signal receiver from the vehicle's main data acquisition unit, placing it on an independent aerial platform. This segmentation provides positioning flexibility, allowing the receiver to be optimally oriented for signal reception while the storage and processing units remain with the vehicle. The separation enables independent optimization of each component's location.
