Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a self-propelled apparatus is equipped with a camera device for automatic weeding, then the automation and intelligence of the apparatus is improved, but the camera device accumulates debris such as grass clippings and dirt which impairs its functionality
Solution Approach 1:
The cleaning assembly is designed to automatically clean the camera lens without external intervention. The cleaning member moves relative to the lens under pressing force, enabling the system to self-maintain camera functionality during operation or when parked.
Solution Approach 2:
The cleaning assembly is positioned and configured in advance to prevent debris accumulation on the camera lens. By having the cleaning member ready and positioned near the lens, the system proactively addresses potential contamination before it significantly impairs camera function.
2Adaptability or versatility
If a cleaning assembly is added to the self-propelled apparatus, then the camera cleaning function is provided, but the device complexity increases
Solution Approach 1:
The cleaning assembly is designed as a separate, modular unit that can be independently mounted on the self-propelled apparatus. This segmentation allows the cleaning function to be added without fundamentally redesigning the entire system, maintaining relative structural simplicity.
Solution Approach 2:
The cleaning assembly with the movable cleaning member can serve multiple purposes: cleaning the camera lens during apparatus operation and providing maintenance when the apparatus is parked. This multi-functionality justifies the added complexity by delivering versatile cleaning capabilities.
3Manufacturing precision
If the cleaning member is designed to move relative to the mounting frame when pressed, then the cleaning effectiveness is improved, but the mechanism complexity increases
Solution Approach 1:
The cleaning member is designed with dynamic movement capability, allowing it to move relative to the mounting frame when pressed by external force. This dynamic design enables the cleaning member to adapt to the lens surface and maintain optimal cleaning contact, improving cleaning precision without requiring complex active control mechanisms.
Solution Approach 2:
The mounting frame serves as an intermediary structure that connects the cleaning assembly to the self-propelled apparatus while allowing relative movement. This intermediary design simplifies the overall mechanism by providing a straightforward mounting interface that accommodates the cleaning member's movement without requiring complex joints or actuators.
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
Effectively solves the issue of debris accumulation on camera lenses by allowing the cleaning member to move relative to the lens, ensuring continuous camera functionality and reducing the need for manual cleaning.
Implementation Method 1
in a case that the cleaning member is pressed by pressing external force, at least the cleaning member moves relative to the mounting frame
Implementation Method 2
the lawn mower with the camera device cannot clean the camera device, and functions of the camera device will be affected dramatically once they are covered with debris such as grass clippings and dirt
