Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional motor driver integration with motors is hindered by heat generation issues, leading to space inefficiencies and limited application flexibility, particularly when both ends of the motor axle are utilized for output.
Innovation Solution
A supporting and heat dissipating structure with a metal heat sink having protrusions for improved heat dissipation, featuring an axle hole and fixing ring for secure motor and driver integration, along with an elastic ring for vibration absorption, allowing the driver to be mounted on the heat sink's inner surface and connected via a tubular barrel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the driver is arranged away from the motor to avoid heat affecting motor speed, then motor operating stability is improved, but space utilization deteriorates and device complexity increases
Solution Approach 1:
The driver is integrated into the motor structure by mounting it on the heat sink, which is already part of the motor assembly. This merging of driver and motor into a single unit eliminates the need for separate mounting structures and wiring harnesses, reducing overall device complexity while maintaining thermal separation through the heat sink design.
2Area of stationary object
If the driver is integrated into the motor structure, then space utilization is improved, but heat dissipation becomes more difficult
Solution Approach 1:
The heat sink acts as an intermediary between the driver and the motor. It provides a thermal pathway that conducts heat away from the driver while allowing the driver to be physically integrated into the motor structure. The heat sink's fins increase surface area for efficient heat dissipation to the surrounding air.
3Stability of the object's composition
If a fixed rigid structure is used for mounting the driver, then structural stability is improved, but vibration resistance deteriorates
Solution Approach 1:
The elastic ring provides flexible mounting that absorbs vibrations between the driver and motor. It maintains the structural connection needed for stability while accommodating dynamic vibrations through its elastic properties, preventing vibration transmission that could affect motor performance or driver reliability.
4Device complexity
If the motor axle is used for single-sided output, then structural simplicity is improved, but application versatility deteriorates
Solution Approach 1:
The heat sink with its central axle hole and fixing ring structure is designed to accommodate motors with axles extending from both ends. This universal mounting structure allows the driver integration to work with various motor configurations (single-sided or dual-sided output) without requiring different mounting designs, thereby increasing application versatility.
