Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing guidance systems for controllable vehicles are not optimal, particularly at higher speeds, as they often require initialization sequences and may result in undetected driving over boundaries, leading to inefficiencies and potential accidents.
Innovation Solution
A guidance system featuring an electrical conductor with a coding device generating a signal code in the conductor current, allowing vehicles to detect and recognize the magnetic field, enabling immediate signal processing and responsive control without the need for initialization pulses, and allowing for precise tracking and area navigation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If traditional guidance systems use simple magnetic field detection without coding, then the system structure remains simple, but the responsiveness and detection accuracy deteriorate at higher vehicle speeds
Solution Approach 1:
The patent applies periodic action by using coded signal sequences with regular patterns of rising and falling edges transmitted through the conductor. The receiving unit detects these periodic magnetic field changes, allowing reliable identification of boundary elements even at high vehicle speeds. The coded structure provides temporal regularity that enables accurate detection without requiring initialization sequences.
2Productivity
If traditional systems require initialization sequences, then the system complexity remains low, but the response time and productivity worsen due to delayed signal processing
Solution Approach 1:
The patent implements preliminary action by continuously transmitting coded signal sequences through the conductor before the vehicle arrives at the boundary. The receiving unit is already prepared to detect and process these pre-established coded signals, eliminating the need for initialization sequences. This allows immediate signal processing and directional correction as soon as the vehicle encounters the conductor.
3Measurement precision
If simple magnetic field detection is used, then the device complexity remains low, but the measurement precision and guidance accuracy deteriorate
Solution Approach 1:
The patent applies local quality by using different coded signal patterns for different boundary elements (e.g., different sequences for entry/exit boundaries or different conductor sections). The receiving unit identifies specific coded patterns to determine precise boundary locations and vehicle orientation. This localized coding provides high measurement precision without requiring complex overall system architecture.
4Reliability
If continuous signal transmission is implemented, then the responsiveness improves, but the energy consumption increases
Solution Approach 1:
The patent uses periodic action with interval signals transmitted through the conductor at optimized time intervals rather than continuous transmission. The receiving unit processes these periodic coded signals reliably, maintaining high guidance reliability while significantly reducing the energy consumption of the stationary conductor system compared to continuous signal transmission.
