Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional intake apparatuses are heavy and prone to fluid leakage due to the need for external power generators, making them difficult to carry and requiring additional sealing processes to ensure watertightness or airtightness.
Innovation Solution
A motor-integrated intake apparatus with a magnetic piston unit and coil unit that forms a magnetic field, allowing for compact design and operation without a separate motor, using a circular housing with an annular flow path, inlet, and discharge units, and a control unit to manage the magnetic field for fluid compression and sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If an external motor is coupled to the compressor main body, then the compressor can draw and compress fluid, but the weight increases and portability becomes difficult
Solution Approach 1:
The motor and compressor main body are merged into a single integrated structure where the piston unit serves as both the compressor element and the motor rotor. The coil unit is installed on the housing to provide rotational power directly to the piston unit, eliminating the need for separate external motor coupling.
Solution Approach 2:
The piston unit performs multiple functions: it acts as both the compressor piston that moves fluid and the rotor of the motor that converts electrical energy to mechanical rotation. This multi-functionality reduces the number of separate components needed.
2Power
If an external motor is coupled to the compressor main body, then power for fluid compression is provided, but fluid leakage occurs at the connecting portion
Solution Approach 1:
By integrating the motor and compressor into a single unit, the connecting portion between external motor and compressor is eliminated. The coil unit is installed directly on the housing, and the piston unit receives rotational power internally, removing the interface where leakage could occur.
Solution Approach 2:
The external motor coupling interface is extracted/removed from the system by implementing an integrated motor-compressor design, thereby eliminating the source of potential fluid leakage at connecting portions.
3Power
If an external motor is coupled to the compressor main body, then power for fluid compression is provided, but additional sealing components and processing are required
Solution Approach 1:
The motor and compressor are combined into one integrated unit, eliminating the need for separate sealing components at the connection interface. The magnetic coupling between the coil unit and piston unit provides inherent sealing without additional mechanical seals.
Solution Approach 2:
The external sealing requirements are extracted/removed by eliminating the external motor coupling, thereby removing the need for additional sealing components and associated processing.
