Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If a power cord is used to provide power to the drill, then the drill can operate continuously, but the drill becomes heavy and cumbersome
Solution Approach 1:
The patent extracts the power source from the external power cord and places it directly into the drill device itself. The power supply unit is integrated within the drill housing, separating the power source from the external environment and eliminating the need for a power cord, thereby reducing weight and improving portability while maintaining continuous operation capability through internal battery power.
Solution Approach 2:
The drill device is designed with multi-functionality by integrating multiple components into a single unified system. The drill housing simultaneously serves as the structural enclosure, the mounting platform for the motor assembly, and the container for the power supply unit. This consolidation creates a self-contained device that functions as both a power consumer and a power holder, eliminating the need for external power infrastructure.
2Duration of action of moving object
If a power cord is used to provide power to the drill, then the drill can operate continuously, but the drill becomes cumbersome for the user to work with
Solution Approach 1:
The patent extracts the power source from the external power cord and places it directly into the drill device itself. The power supply unit is integrated within the drill housing, separating the power source from the external environment and eliminating the need for a power cord, thereby reducing weight and improving portability while maintaining continuous operation capability through internal battery power.
Solution Approach 2:
The drill device is segmented into distinct functional modules: a motor assembly with motor housing and motor, a power supply unit with battery cells, and a control system. This segmentation allows each component to be optimized independently and assembled into a compact configuration that enhances ease of operation while providing continuous power through the integrated battery system.
3Weight of moving object
If the drill is made lightweight and portable, then the user can conveniently carry it on the body, but the power supply capability may be compromised
Solution Approach 1:
The patent employs a compact, lightweight housing structure that encloses the power supply unit and motor assembly. The housing is designed with optimized wall thickness and material selection to minimize weight while maintaining structural integrity and protecting the internal components. This flexible yet protective enclosure allows the drill to be carried conveniently on the user's body while housing sufficient power supply components.
Solution Approach 2:
The power supply unit is nested within the drill housing, which itself contains the motor assembly. This nested configuration maximizes space utilization and minimizes the overall external dimensions of the drill, reducing weight and improving portability while maintaining adequate power supply capability through the integrated battery system.
