Compressor Mounting Structure for Engine Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation and removal of compressors in engines, such as those in personal watercraft, are difficult due to the need to maneuver the compressor parallel to the crankshaft, requiring significant space and a tedious process.
Innovation Solution
A modified mounting arrangement where the installation mount extends parallel to the crankshaft, with a surface facing the engine compartment opening, allowing the compressor to be mounted with a directly-coupled gear train that transmits driving force, and screw holes oriented perpendicular to the surface for secure attachment, reducing the need for compressor movement during installation and removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the compressor is installed using the conventional mounting arrangement, then the compressor can be secured to the engine, but the installation and removal process becomes tedious and difficult requiring significant space
Solution Approach 1:
The patent inverts the conventional mounting approach by extending the installation mount perpendicular to the crankshaft axis instead of parallel to it. This allows the compressor to be mounted directly onto the front end of the engine through the opening, eliminating the need for tedious parallel movement and making installation and removal straightforward operations.
Solution Approach 2:
The installation mount extends in a different dimension (perpendicular to the crankshaft axis) rather than following the conventional parallel arrangement. This dimensional change allows the compressor to be accessed and mounted directly through the opening without requiring lateral movement space, simplifying the installation process.
2Ease of manufacture
If the compressor is moved parallel to the crankshaft during installation, then the compressor can be positioned on the mounting surface, but significant space within the engine compartment is required
Solution Approach 1:
Instead of moving the compressor parallel to the crankshaft as in conventional designs, the mount extends perpendicular to the crankshaft axis. This inversion allows the compressor to be positioned directly through the opening without requiring lateral movement space within the engine compartment.
Solution Approach 2:
The installation mount is pre-configured to extend perpendicular to the crankshaft axis with the mounting surface facing the opening. This preliminary arrangement allows the compressor to be directly placed onto the mount through the opening without requiring subsequent lateral movement or additional space manipulation.
3Reliability
If the mounting surface faces away from the opening, then the compressor can be secured parallel to the crankshaft, but the installation process becomes more complex and time-consuming
Solution Approach 1:
The mounting surface is oriented to face the opening rather than away from it, and the mount extends perpendicular to the crankshaft axis. This inverted configuration allows the compressor to be directly attached through the opening in a single straightforward operation, eliminating the need for complex positioning and reducing installation time.
Solution Approach 2:
The installation mount is pre-configured with the mounting surface facing the opening, allowing the compressor to be directly secured in one action. This eliminates the need for subsequent adjustment or repositioning steps, significantly reducing installation and removal time while maintaining secure attachment.

Function Achieved in This Case
This configuration simplifies the installation and removal of the compressor, reduces space requirements, and ensures efficient torque transmission, preventing time lag and excessive supercharging, while also protecting the compressor from torque fluctuations.
