Dual-Motor Control Valve Drive Layout for Compact Wiring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing control valves face challenges in miniaturization due to the large size of driving devices, which occupy excessive space and hinder compact design.
Innovation Solution
The proposed solution involves a driving device with a housing and a dual motor assembly, where the first and second motors are arranged at an interval along the length direction, facilitating centralized wiring and reducing the size by overlapping wiring segments with motor bodies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the driving device uses a conventional arrangement with motors positioned far apart, then wiring is simpler, but the device occupies more space and hinders miniaturization
Solution Approach 1:
The patent merges the power supply terminals of the first and second motors by positioning them adjacent to each other, allowing wire segments to be shared between both motors. This reduces the total number of wires needed while maintaining compact motor spacing, thereby reducing the overall device volume without excessively increasing wiring complexity
Solution Approach 2:
The patent repositions the power supply terminals from a conventional side-by-side arrangement to an adjacent arrangement at the ends of the motor bodies, creating a three-dimensional wiring layout that reduces the gap between motors while allowing wires to extend in multiple directions, thus reducing device footprint
2Length of stationary object
If the driving device minimizes the gap between motors, then the overall size is reduced, but wiring becomes more complex and difficult to manage
Solution Approach 1:
By positioning the power supply terminals adjacent to each other, the patent enables multiple wire segments to be merged into shared pathways, reducing the number of separate wiring routes needed while maintaining minimal distance between motors
Solution Approach 2:
The adjacent power supply terminal arrangement creates a universal wiring point that serves both motors, allowing the same wire segments to fulfill multiple functions by connecting to different motors, thereby simplifying the overall wiring system despite compact motor spacing
