Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the battery is mounted on the abrading-machine main body to improve weight balance, then the weight balance and stability are improved, but the weight of the main body increases and ease of operation deteriorates
Solution Approach 1:
The system is divided into two separate components: the abrading-machine main body and the battery holster. The battery is mounted on the holster rather than integrated into the main body, allowing the main body to remain lightweight while the holster provides ballast for weight balance during operation.
Solution Approach 2:
The power-supply cord acts as an intermediary connection between the abrading-machine main body and the battery holster. This cord couples the two separate components without requiring the battery to be physically integrated into the main body housing, enabling both separation for weight reduction and connection for power supply.
2Device complexity
If the battery is mounted on the abrading-machine main body to reduce device complexity, then the structure is simplified, but vibration from orbital motion damages the battery and reduces service life
Solution Approach 1:
The battery and abrading-machine main body are segmented into separate units. The battery resides in the holster while the main body contains the orbital motion mechanism, physically isolating the battery from vibration sources.
Solution Approach 2:
The battery is extracted from the main body housing and placed in a separate holster. This extraction removes the battery from the vibration environment created by orbital motion, protecting it from damage while maintaining operational functionality through the power-supply cord connection.
3Device complexity
If the power-supply cord goes through the housing to connect battery and motor, then the connection is simplified, but vibration damages the cord and increases device complexity
Solution Approach 1:
The power-supply cord serves as an external intermediary connector between the battery holster and abrading-machine main body. Rather than routing the cord through the housing, it connects the two separate components externally, avoiding vibration-induced damage while maintaining electrical connectivity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design enhances ease of operation by reducing the weight of the abrading machine and prolonging the service life of the battery and its mounting parts, while maintaining the machine's compactness and efficiency.
Implementation Method 1
electric power (current) from a battery is supplied to a motor, and thereby an abrading pad moves with rotational motion and eccentric motion
Implementation Method 2
an abrading pad moves with rotational motion and eccentric motion, i.e. orbital motion

AI summary
A portable abrading machine includes an abrading-machine main body, a battery holster, and a power-supply cord. The abrading-machine main body includes a main-body housing, which houses a motor, and an abrading part, which is configured to move with orbital motion when a motor shaft of the motor is rotated. The battery holster includes a battery-mounting part, on which a battery is mountable. The power-supply cord is configured to supply electric power from the battery, when mounted on the battery-mounting part, to the abrading-machine main body. The power-supply cord connects the abrading-machine main body and the battery holster without going through the housing.
