Bicycle Tyre Pressure Control via Wireless Sensor and Database
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of two-wheeler tires, such as bicycles, often lack knowledge of the standard target pressure and fail to account for their weight, the weight of additional loads, and route profiles when inflating tires, leading to ineffective pressure control.
Innovation Solution
A method utilizing a computing device and mobile application that determines a situation-specific target pressure by gathering user input and data from a database, which includes information on rider weight, load, route profile, and tire type, and uses wireless sensors to monitor and adjust tire pressure in real-time, providing visual and auditory feedback to maintain optimal pressure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a standard target pressure is used for tire inflation, then the inflation process is simple, but the pressure control is not adapted to specific conditions such as rider weight, load, and route profile
Solution Approach 1:
The system performs preliminary actions by pre-calculating and storing optimal target pressures in a database for various tire types and conditions (rider weight, load, route profile) before the actual inflation process. This allows the user to simply select their conditions and receive the appropriate target pressure without manual calculation or complex adjustments during inflation.
Solution Approach 2:
The system introduces an intermediary element - a database containing pre-determined target pressure values for different tire types and riding conditions. This database acts as a mediator between the user's input (tire type, weight, load, route) and the inflation process, providing adaptive pressure control without requiring complex real-time calculations during inflation.
2Reliability
If real-time pressure monitoring and adjustment is implemented, then tire pressure control is optimized for specific conditions, but the device complexity increases
Solution Approach 1:
The system achieves multi-functionality by combining several functions into a single integrated device: pressure sensing, wireless data transmission, target pressure determination based on multiple parameters (weight, load, route), and automated inflation/deflation control. This universal approach optimizes reliability without proportionally increasing complexity, as one device performs multiple coordinated functions.
Solution Approach 2:
The system implements feedback by continuously monitoring actual tire pressure via sensors and comparing it with the target pressure determined from rider weight, load, and route profile. This feedback loop enables automated adjustment of inflation/deflation to maintain optimal pressure, improving reliability while using standard control mechanisms.
3Measurement precision
If user-specific information (weight, load, route profile) is collected and processed, then situation-specific target pressure can be determined, but the information processing requirements increase
Solution Approach 1:
The system performs preliminary action by pre-processing and storing optimal target pressure values in a database for various combinations of tire types, rider weights, loads, and route profiles. During actual use, the system simply retrieves the appropriate pre-calculated value based on user input, achieving high measurement precision without complex real-time calculations.
Solution Approach 2:
The system uses copying by storing pre-determined target pressure values in a database that can be accessed and reused for similar riding conditions. Instead of recalculating optimal pressure each time, the system copies appropriate target values from the database based on matching conditions, reducing information processing requirements while maintaining precision.
