Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems fail to effectively eliminate humidity in the inner cavity of pneumatic tires and efficiently warm the entire rolling assembly within a reasonable duration, leading to excessive internal pressure increases during usage.
Innovation Solution
A system comprising a circulator, dryer, intake mean, and exhaust mean to circulate, dry, and exhaust gas within the inner cavity, along with optional heating means and connecting mechanisms to enhance drying and warming efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a tire warmer is used to warm the outer circumference of the tire, then the outer circumference temperature is improved, but the internal construction (especially the tread) does not reach desired temperature and excessive pressure increase occurs
Solution Approach 1:
Instead of heating from the outside (conventional tire warmer approach), the invention introduces heated dry gas from the inside of the tire cavity. This internal heating approach allows direct thermal contact with the internal construction including the tread, ensuring uniform temperature distribution throughout the tire structure while preventing excessive pressure increases.
Solution Approach 2:
The invention uses a pneumatic system to circulate heated dry gas through the tire cavity. Gas introduction means introduce heated dry gas into the tire, and gas exhaust means remove it, creating a circulating pneumatic system that efficiently transfers heat from the inside out, solving the temperature uniformity problem while controlling pressure.
2Stress or pressure
If dried gas is introduced into the inner cavity to minimize excessive pressure increase, then pressure control is improved, but humidity elimination is not satisfactory
Solution Approach 1:
The invention implements continuous circulation of dry gas through the tire cavity using gas introduction means and gas exhaust means. This continuous flow systematically removes humidity over time while maintaining controlled pressure levels, achieving both humidity elimination and pressure control simultaneously through sustained pneumatic circulation.
3Loss of time
If conventional tire warming is applied, then preparation time is reduced, but the entire rolling assembly is not warmed uniformly within reasonable duration
Solution Approach 1:
The invention reverses the conventional heating approach by introducing heated gas from the inside of the tire rather than heating from the outside. This internal heating method directly warms the tire's internal construction and tread, achieving uniform temperature distribution throughout the entire rolling assembly in a reasonable preparation time.
