Air Compressor Motor Locking Mount for Screwless Fixation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air compressor motors are difficult to fix securely and remove easily due to the limited space and requirement for screws, making it challenging to maintain and assemble within an accommodation box.
Innovation Solution
The fixing device employs multiple coupling orifices on the motor to engage with posts on the body, along with locking extensions that securely connect the motor without screws, allowing for easy removal using a tool that presses the locking extensions away from the body, and utilizes flexible wings to stabilize the air compressor in the accommodation box.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If screws are used to fix the motor on the body, then the motor can be securely fixed, but it becomes difficult to operate in limited space and requires multiple threaded orifices
Solution Approach 1:
The patent removes the screws and threaded orifices from the fixation system, extracting the fastening function into a different mechanism. The locking extensions with flexible wings provide fixation without requiring traditional screw threads, eliminating the need for tools and simplifying operation in limited spaces.
Solution Approach 2:
The patent replaces the screw-thread mechanical fastening system with a locking extension mechanism featuring flexible wings that engage with slots in the body. This substitution eliminates the complexity of multiple threaded orifices and tool requirements while maintaining secure fixation.
2Strength
If multiple threaded orifices are used on the motor casing, then the motor can be fixed with screws, but the structure becomes complex and difficult to assemble in limited space
Solution Approach 1:
The patent extracts the fastening function from the motor casing structure, removing the need for multiple threaded orifices. The locking extensions integrate the fixation mechanism into a simple engagement system with the body slots, dramatically reducing structural complexity.
Solution Approach 2:
The patent merges the fixation function into the locking extensions that engage with the body slots, combining multiple fastening points into a unified mechanism. This eliminates the need for separate threaded orifices and simplifies the overall structure.
3Strength
If screws are used to fix the motor, then the motor can be securely attached, but removal becomes time-consuming and requires tools
Solution Approach 1:
The patent removes the screws and tool-based fastening system, replacing them with a manual push-to-release mechanism. The flexible wings can be easily depressed to release the locking extensions, enabling quick removal without tools and significantly reducing time loss.
Solution Approach 2:
The patent inverts the traditional fastening approach: instead of requiring force to tighten and then force or tools to loosen screws, the system uses a simple push action to engage and a reverse push action to disengage, making removal as easy as attachment.
4Strength
If the motor is fixed with screws through the body, then the motor can be secured, but the accommodation box space utilization is reduced
Solution Approach 1:
The patent extracts the fastening elements (screws and threaded orifices) from the motor and body structure, eliminating the space they would occupy. The locking extensions engage with slots that require minimal space, maximizing the accommodation box volume available for other components.

AI summary
An air compressor is received in an accommodation box and contains a body, a cylinder, a motor, and a transmission mechanism. The body includes a first positioning orifice and a second positioning orifice. The cylinder is connected on the body and communicates with an air storage holder. The motor is fixed on the body, a small gear is received in the first positioning orifice, and a connection seat is accommodated in the first orifice. The transmission mechanism actuates a piston to move in the cylinder reciprocately so as to produce compressed air. The motor includes at least one locking extension for engaging the motor with the body. A first end of a respective one locking extension extends from the motor, and a second end of the respective one locking extension is engaged on the body, hence the motor is fixed on the body securely without using any screws.
