Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a robotic arm is combined with a track to expand working range, then positioning accuracy is improved, but mobility and real-time movement ability deteriorate because the track needs to be laid according to site conditions
Solution Approach 1:
The system is divided into three independent modules: mobile platform module, carrier module, and robotic arm module. Each module can move independently, allowing the robotic arm to maintain positioning accuracy through the carrier module's guide rails while the mobile platform provides real-time mobility across the construction site
Solution Approach 2:
The carrier module acts as an intermediary between the mobile platform and the robotic arm. It provides a stable mounting base with guide rails for positioning accuracy while allowing the mobile platform to provide real-time movement capability
2Adaptability or versatility
If a robotic arm is combined with a gantry to provide large working range, then construction flexibility is improved for large-volume projects, but the system becomes less adaptable to different construction sites because the gantry must be larger than the structure to be constructed
Solution Approach 1:
The system uses a mobile platform with wheels that can dynamically adjust its position on the construction site, replacing the static gantry structure. The carrier module can extend and retract, allowing the system to adapt to different construction site layouts and structure sizes without requiring a fixed large-span gantry
Solution Approach 2:
The system adds vertical mobility through the lifting platform module, enabling the robotic arm to reach different heights. This vertical dimension complemented by the mobile platform's horizontal movement provides three-dimensional flexibility without requiring a large horizontal gantry structure
3Ease of operation
If a robotic arm is combined with a mobile platform to provide mobility, then working range is expanded, but positioning accuracy deteriorates because wheeled or tracked platforms have low positioning accuracy
Solution Approach 1:
The system separates mobility and positioning functions into different modules: the mobile platform module provides mobility and working range, while the carrier module with its guide rails provides positioning accuracy. This segmentation allows each module to optimize its specific function without compromising the other
Solution Approach 2:
The carrier module serves as an intermediary that receives the robotic arm from the mobile platform and provides a stable, accurate positioning base. The guide rails in the carrier module ensure positioning accuracy while the mobile platform maintains mobility capability
