Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a robotic drilling apparatus is used to automate drilling operations, then productivity and manufacturing precision are improved, but device complexity increases
Solution Approach 1:
The robotic drilling apparatus is divided into distinct functional modules: a robotic arm for positioning, a drilling device for hole creation, a control unit for automation, and a vibration reducing assembly for noise control. This segmentation allows each component to be optimized independently while maintaining overall system productivity and precision without excessive complexity.
2Object-affected harmful factors
If a vibration reducing assembly is added to the drilling device, then harmful factors are reduced, but device complexity increases
Solution Approach 1:
A vibration reducing assembly is introduced as an intermediary component between the drilling device and the robotic arm. This assembly includes vibration isolation elements that absorb and dampen vibrations generated during drilling, preventing them from being transmitted to the robotic arm and reducing noise levels, thereby protecting the work environment without complicating the core drilling function.
3Manufacturing precision
If manual marking and positioning is performed, then device complexity is reduced, but manufacturing precision deteriorates
Solution Approach 1:
The control unit replaces manual marking and positioning operations with automated digital control. The system uses electronic coordinates from BIM files to precisely position the drilling device, eliminating the need for manual measurement and marking tools. This substitution of mechanical positioning with automated digital control achieves high precision without adding significant physical complexity to the apparatus.
4Force
If heavy drilling equipment is used for concrete drilling, then power and force are improved, but weight increases
Solution Approach 1:
The robotic arm is equipped with a counterweight mechanism that balances the weight of the drilling device. This counterweight system offsets the gravitational force acting on the heavy drilling equipment, allowing the robotic arm to maneuver the high-power drilling device with minimal effort. The counterweight enables the system to maintain high drilling force while reducing the effective weight burden on the robotic positioning system.
