Solution Overview
Problem
Conventional centrifugal valve control apparatuses face challenges in accurately controlling the opening of channels due to incomplete melting of phase transition materials, primarily because of inefficient energy transfer and incorrect positioning of heating members during rotation.
Innovation Solution
A centrifugal valve control apparatus with a heating member positioned corresponding to the valve, a fixing unit to maintain the heating member's position during rotation, and a heat transfer member to ensure effective heat transfer, along with a controlling part to adjust energy application based on valve material and rotational speed, ensuring complete melting and accurate valve control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a laser light source is used to irradiate electromagnetic waves to the valve material through the centrifugal valve control apparatus during rotation, then the valve material can be melted to open the channel, but the laser light source is difficult to correctly irradiate the laser to the valve position due to rotation, resulting in low valve control accuracy
Solution Approach 1:
The heating member is integrated directly into the centrifugal valve control apparatus structure, merging the heating function with the rotating platform. This ensures that the heating member rotates synchronously with the apparatus, maintaining accurate positional correspondence with the valve material throughout rotation, thereby solving the irradiation precision problem.
Solution Approach 2:
A heat transfer member is introduced as an intermediary between the heating member and the valve material. This heat transfer member efficiently conducts heat from the heating member to the valve material, ensuring complete melting even during rotation, thereby improving valve control reliability.
2Use of energy by moving object
If the heating member position is not correctly maintained during rotation, then energy cannot be correctly transferred to the phase transition material, but maintaining precise positioning during high-speed rotation is mechanically challenging
Solution Approach 1:
The heating member is merged with the centrifugal valve control apparatus structure, ensuring synchronous rotation. This integration guarantees that the heating member maintains correct positional relationship with the valve material throughout the rotation cycle, enabling efficient energy transfer without requiring complex external positioning mechanisms.
Solution Approach 2:
The heat transfer member acts as an intermediary that ensures efficient energy transfer from the heating member to the valve material. This intermediary component compensates for any minor positioning variations and ensures complete energy transfer to melt the phase transition material reliably.
3Ease of operation
If a phase transition material is used to control the valve, then the channel can be opened by melting the material, but the phase transition material is not completely melted due to insufficient energy transfer, resulting in incomplete channel opening
Solution Approach 1:
The heat transfer member is positioned between the heating member and the valve material to ensure efficient and complete heat transfer. This intermediary component guarantees that sufficient energy is transferred to completely melt the phase transition material, ensuring reliable and complete channel opening while maintaining simple valve operation.
Solution Approach 2:
The system controls the heating parameters (temperature, duration) to ensure complete melting of the phase transition material. By adjusting these parameters and ensuring proper energy transfer through the heat transfer member, the valve achieves reliable opening without compromising operational simplicity.
