Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fossil fuel-based engines are used in outdoor power equipment, then power and reliability are maintained, but emission compliance costs increase and control features are limited
Solution Approach 1:
The patent replaces the mechanical internal combustion engine system with an electrical powertrain system consisting of battery packs and electric motors. This substitution eliminates emissions entirely while enabling sophisticated electronic control features through the controller that receives user inputs and manages motor operation, directly resolving the contradiction between emission compliance and control capability.
2Object-generated harmful factors
If electric motors and batteries are used instead of fossil fuel engines, then emissions are eliminated and control features are enhanced, but device complexity increases
Solution Approach 1:
The controller serves multiple functions: it receives inputs from user input devices, processes sensor data, controls the electric motors for both propulsion and implement operation, and manages battery power distribution. This multi-functionality consolidates what would otherwise be separate control systems into a single unit, reducing overall system complexity despite the electric powertrain's additional components.
Solution Approach 2:
The controller acts as an intermediary between the user input devices, sensors, batteries, and electric motors. It coordinates all system components through centralized electronic control, managing the complexity of the electric powertrain by providing a single point of control that simplifies system integration and operation.
3Ease of operation
If sophisticated control systems with sensors and user input devices are integrated, then user experience and adaptability improve, but device complexity and manufacturing costs increase
Solution Approach 1:
The patent merges the user input devices, sensors, controller, and motor control functions into an integrated electronic control system. The controller consolidates processing of user inputs and sensor data while managing both propulsion and implement operations, creating a unified control architecture that improves user experience without proportionally increasing complexity.
