Motor Fixing Ring Assembly for Inflator Heat Dissipation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional inflators suffer from inefficient heat dissipation due to their structural design, leading to motor overheating and potential damage during use.
Innovation Solution
An inflator with a motor fixing ring that creates an air gap between the motor and the casing, allowing a cooling fan to dissipate heat effectively by flowing air through this gap, enhancing cooling efficiency and performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the motor is installed directly in the casing without an air gap, then the device complexity is reduced, but the heat dissipation efficiency deteriorates causing motor overheating
Solution Approach 1:
The motor assembly is segmented from the casing by introducing a motor fixing ring that creates a distinct air gap zone. This segmentation allows independent optimization of motor mounting and heat dissipation functions, enabling the air gap to be specifically designed for thermal management without compromising overall structural integrity.
Solution Approach 2:
The motor fixing ring acts as an intermediary component between the motor and the casing. It introduces the air gap that serves as a thermal mediator, allowing heat to be dissipated from the motor to the surrounding environment while maintaining mechanical support and positioning functions.
2Reliability
If an air gap is introduced between the motor and casing for heat dissipation, then the cooling efficiency is improved, but the device complexity increases due to the motor fixing ring
Solution Approach 1:
The motor fixing ring is designed to perform multiple functions simultaneously: it provides mechanical support for the motor, maintains the air gap for heat dissipation, and ensures proper positioning within the casing. This multi-functionality reduces the need for separate components, thereby minimizing the increase in device complexity while achieving improved cooling efficiency.
Solution Approach 2:
The motor fixing ring combines several functions into a single component: structural support, air gap maintenance, and thermal management facilitation. By merging these functions, the design avoids adding multiple separate parts that would increase complexity, while still achieving the desired cooling efficiency improvement.

AI summary
An inflator with a motor fixing ring includes a casing, and a core and a motor installed in the casing. The motor is for driving the core to inflate an external object. The inflator further includes a motor fixing ring sheathed on the motor and clamped between the motor and the casing. An air gap is formed between an outer surface of the motor and an inner surface of the casing. During the use of the inflator, the motor fixing ring is sheathed on the motor, and the motor is installed into the casing, so that the motor fixing ring is clamped between the motor and the casing. A cooling fan of the inflator is provided for flowing air along the air gap to dissipate the heat generated by the motor, so as to improve the cooling efficiency of the motor and the performance of the inflator.
