Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle transmission-reception systems lack the ability to properly control vehicles based on the type of tire valve attached, leading to inconsistent performance and safety issues due to varying tire pressure and vehicle speed thresholds.
Innovation Solution
A transmitter and receiver system that includes an acceleration sensor to determine the type of tire valve, generating and transmitting valve identification information to set appropriate thresholds for vehicle control, ensuring proper vehicle control by recognizing and adapting to snap-in or clamp-in valves.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a transmitter is designed to be attachable to multiple types of tire valves, then the adaptability of the system is improved, but the ability to properly control the vehicle deteriorates due to inability to distinguish valve types
Solution Approach 1:
The patent uses centrifugal acceleration detection to identify valve types, analogous to using distinctive markers. The acceleration sensor detects characteristic acceleration patterns that differ between snap-in and clamp-in valves, enabling automatic identification and appropriate control parameter selection, thus resolving the contradiction between universal compatibility and accurate control.
2Device complexity
If the system uses a single threshold for all valve types, then the device complexity is reduced, but the control precision deteriorates
Solution Approach 1:
The patent implements dynamic threshold adjustment based on detected valve type. The system automatically selects different control thresholds depending on whether a snap-in or clamp-in valve is detected, enabling precise control for each valve type without requiring manual configuration or complex fixed threshold mechanisms.
3Measurement precision
If the transmitter includes acceleration sensor and determination unit, then the measurement precision of valve type is improved, but the device complexity increases
Solution Approach 1:
The patent employs self-service by using the existing rotational motion of the wheel to generate centrifugal acceleration that automatically identifies the valve type. The system leverages the natural physical phenomenon occurring during vehicle operation rather than requiring additional active components or manual intervention, thus improving measurement precision while minimizing added complexity.

AI summary
A transmitter includes a data generating unit configured to generate transmission data, a transmitting unit configured to transmit the transmission data to a receiver that includes a setting unit that sets a threshold for controlling a vehicle in accordance with the type of the tire valve, and a controlling unit that causes the transmitting unit to transmit the transmission data. The transmission data is information with which the setting unit sets the threshold. The transmission data includes valve identification information for causing the setting unit to recognize the type of the tire valve to which the transmitter is attached.
