Tire Vulcanizing Heating Path Through Pressure Body to Reduce Heat Loss
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tire vulcanizing apparatuses experience significant heat loss due to convective heat transport through recesses and openings in the insulating body, which are necessary for accommodating tires of different shapes and sizes, leading to inefficient energy use.
Innovation Solution
The fluid path for temperature control medium, such as steam, is routed outside the annular heating body through a vertically movable pressure body, eliminating the need for recesses and openings in the insulating body, thereby reducing convective heat loss and enhancing energy efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the insulating body has recesses and openings to accommodate different tire receiving units, then the apparatus can vulcanize tires of different shapes and sizes, but significant heat loss occurs through convective heat transport
Solution Approach 1:
The fluid path for the temperature control medium is extracted from the annular heating body and routed through the vertically movable pressure body instead. This relocation eliminates the need for recesses and openings in the insulating body, as the fluid connections are now accessible through the pressure body's movement path rather than through the insulating structure.
Solution Approach 2:
The vertically movable pressure body serves as an intermediary element that provides access to the fluid path connections. By routing the temperature control medium through this movable component, the system maintains adaptability for different tire sizes while preventing direct convective heat loss through the insulating body.
2Adaptability or versatility
If recesses and openings are provided in the insulating body for fluid path connections, then different tire receiving units can be accommodated, but heat exchange with the environment increases
Solution Approach 1:
The fluid path connections are extracted from the insulating body structure and relocated to the vertically movable pressure body. This eliminates the harmful effect of heat exchange through the insulating body's recesses and openings while preserving the capability to accommodate different tire receiving units.
Solution Approach 2:
Instead of providing fixed openings in the insulating body for fluid connections, the solution inverts the approach by making the pressure body movable to access the fluid path. This reverses the traditional design where the insulating body had to compromise its integrity for connection access.
3Use of energy by stationary object
If the fluid path is routed through the annular heating body with connections in the insulating body, then heating is effective, but energy efficiency decreases due to heat loss
Solution Approach 1:
The fluid path is extracted from the annular heating body and routed through the vertically movable pressure body. This maintains effective heating of the tire receiving unit while eliminating energy loss through the insulating body's openings, thereby improving overall energy efficiency.
Solution Approach 2:
By routing the temperature control medium through the pressure body rather than through openings in the insulating body, the system maintains continuous and efficient heat transfer to the tire receiving unit without interruption or loss through the insulation barrier.
