Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a robotic arm is used to perform construction tasks, then three-dimensional movement capability is achieved, but programming complexity increases
Solution Approach 1:
The system divides the movement capability into two separate components: a mobile platform that provides two-dimensional movement (forward/backward, left/right) and a rotatable arm that provides vertical movement and tool positioning. This segmentation allows each component to be controlled independently, simplifying the overall programming compared to a single three-degree-of-freedom robotic arm
Solution Approach 2:
The mobile platform serves multiple functions: it provides the base for the rotatable arm, enables two-dimensional movement of the entire system, and can be controlled to position the arm over different work areas. This multi-functionality reduces the need for separate positioning mechanisms, thereby reducing programming complexity
2Adaptability or versatility
If multiple tools are installed on the workstation, then versatility for different construction jobs is improved, but device complexity increases
Solution Approach 1:
The rotatable arm is designed to accommodate multiple different tools at its end effector, allowing a single workstation to perform multiple construction tasks such as drilling, painting, and fastening. The tool interface is standardized to simplify tool changes, maintaining low complexity while achieving high versatility
Solution Approach 2:
The rotatable arm can dynamically reposition and swap between different tools based on the construction task requirements. This dynamic adaptability allows the system to handle diverse construction jobs with a single unified platform, avoiding the need for multiple specialized workstations
3Ease of operation
If the platform is made lightweight to enable lifting by flexible lift, then ease of operation is improved, but structural strength may be compromised
Solution Approach 1:
The platform structure uses local quality optimization by employing lightweight materials and optimized structural design in non-critical areas while maintaining adequate structural strength in load-bearing components. This allows the platform to be lightweight enough for flexible lift operation while still supporting the tools and withstanding operational loads
Solution Approach 2:
The platform likely utilizes composite materials that provide high strength-to-weight ratio, combining lightweight properties for ease of lifting with sufficient structural strength to support tools and withstand construction operational forces
