Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional multi air chamber tires require significant time and effort to adjust internal pressures across multiple air chambers, limiting convenience.
Innovation Solution
A multi air chamber tire with a ventilation member that regulates ventilation between air chambers based on predetermined conditions, allowing or shutting off airflow when fluid is injected or leaked, ensuring efficient pressure control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple air chambers are used to maintain safe travel distance, then reliability is improved, but adjustment of internal pressures becomes more time-consuming and complex
Solution Approach 1:
The tire is divided into multiple independent air chambers separated by partition walls, allowing the tire to maintain reliability even when one chamber loses pressure. Each chamber can be independently managed, and the segmentation enables continuous travel capability while simplifying pressure adjustment through selective communication between chambers.
Solution Approach 2:
A ventilation member acts as an intermediary mechanism between air chambers, controlling the communication and pressure equalization between them. This mediator enables efficient pressure adjustment by allowing operators to open or close specific chambers for inflation, reducing the time required compared to managing multiple independent chambers.
2Reliability
If multiple air chambers are used to maintain safe travel distance, then reliability is improved, but device complexity increases
Solution Approach 1:
The tire is divided into multiple independent air chambers separated by partition walls, allowing the tire to maintain reliability even when one chamber loses pressure. Each chamber can be independently managed, and the segmentation enables continuous travel capability while simplifying pressure adjustment through selective communication between chambers.
Solution Approach 2:
The ventilation member serves multiple functions: it controls pressure equalization between chambers, enables selective inflation of individual chambers, and facilitates maintenance operations. This multi-functional component reduces the need for separate mechanisms for each air chamber, thereby managing device complexity while maintaining reliability.
3Ease of operation
If ventilation between air chambers is always open, then pressure adjustment is simplified, but control over individual chamber pressures is lost
Solution Approach 1:
The ventilation member provides dynamic control over chamber communication, allowing it to switch between open and closed states based on operational requirements. This dynamic capability enables operators to equalize pressures across chambers when needed while maintaining independent pressure control when required, balancing ease of operation with adaptability.
Solution Approach 2:
A ventilation member acts as an intermediary mechanism between air chambers, controlling the communication and pressure equalization between them. This mediator enables efficient pressure adjustment by allowing operators to open or close specific chambers for inflation, reducing the time required compared to managing multiple independent chambers.

AI summary
A multi air chamber tire 1 includes a partition wall 30 configured to define and form a plurality of air chambers 20 disposed adjacent to each other in an inner cavity of a tire, and a ventilation member 10 provided to the partition wall 30, and configured to connect the plurality of air chambers 20 in a state where ventilation is allowed. The ventilation member 10 allows ventilation between the plurality of air chambers 20 when a predetermined condition is satisfied indicating that fluid is being injected into at least one of the plurality of air chambers 20 from outside of the tire, and the ventilation member 10 shuts off the ventilation between the plurality of air chambers 20 when the predetermined condition is not satisfied.
