Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remotely controlled central heating radiator valves face issues with durability due to axial pressure on the electric micro-motor and reduction gear, which affects their service life and reliability.
Innovation Solution
A design featuring a body with shaped guides allowing the electric micro-motor and reduction gear to slide freely, eliminating axial forces and using an intermediate element with low friction to regulate the control needle, ensuring only torque is transmitted, thus avoiding axial pressure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the electric micro-motor and reduction gear are fixed rigidly in the body, then the structure is simple and stable, but axial pressure is transmitted to the motor and gear which reduces durability
Solution Approach 1:
The body is divided into functional zones with shaped guides creating separate sliding paths for the micro-motor and reduction gear. This segmentation allows the power unit components to move independently along defined trajectories, preventing axial force transmission while maintaining structural organization and simplicity.
Solution Approach 2:
Shaped guides act as intermediary elements between the rigid body structure and the movable power unit components. These guides transmit only the necessary torque while blocking axial pressure, serving as a mechanical mediator that protects the motor and gear from harmful forces.
2Reliability
If the shift screw directly contacts the control needle, then the control mechanism is simple, but friction and wear increase reducing service life
Solution Approach 1:
An intermediate element is introduced between the shift screw and control needle to eliminate direct metal-to-metal contact. This intermediary component reduces friction and wear while maintaining the simplicity of the control mechanism, thereby extending service life without adding significant complexity.
Solution Approach 2:
The direct mechanical contact between shift screw and control needle is replaced with an intermediate element that reduces friction. This substitution changes the mechanical interaction from high-friction direct contact to low-friction mediated contact, improving durability.
3Power
If the micro-motor and reduction gear are subjected to axial pressure during operation, then the torque transmission is effective, but the bearing and gear durability decreases
Solution Approach 1:
The power unit components are designed to slide dynamically along shaped guides rather than being rigidly fixed. This dynamic arrangement allows the micro-motor and reduction gear to move freely in the axial direction, transmitting only torque while eliminating axial pressure loads, thereby protecting bearings and gears from premature failure.
Solution Approach 2:
Axial pressure forces are extracted and removed from the torque transmission path. The shaped guides and sliding mechanism separate the torque transmission function from axial loading, allowing the motor and gear to perform their primary function without承受 harmful axial forces.
