Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a worker uses a chainsaw to bisect a slaughtered animal, then the cutting process can be performed manually, but the work result varies depending on the worker's skill level
Solution Approach 1:
The patent replaces the manual chainsaw operation with an automated robotic system. The robot arm holds and operates the chainsaw according to pre-programmed trajectories, eliminating the dependency on worker skill levels. The automated control system ensures consistent cutting quality across different operations and workers.
2Productivity
If a worker repeatedly holds the chainsaw to bisect carcasses, then the cutting process can be performed, but the worker can suffer from musculoskeletal disorders
Solution Approach 1:
The robotic system replaces the human worker's physical interaction with the chainsaw. The robot arm, powered by automated actuators, holds and maneuvers the chainsaw along predetermined paths, completely eliminating the physical strain that causes musculoskeletal disorders in manual operations.
Solution Approach 2:
The robotic system performs the cutting operation autonomously without human intervention during the actual cutting process. The robot navigates, positions, and operates the chainsaw independently, making the system self-sufficient for the bisecting task while protecting workers from physical harm.
3Productivity
If foreign substances stick to the chainsaw during the bisecting process, then the cutting can be performed, but microorganisms proliferate causing carcass rot
Solution Approach 1:
The system continuously sprays water onto the chainsaw blade during the entire cutting operation. This continuous cleaning action prevents foreign substances and biological materials from accumulating on the blade, thereby preventing microorganism proliferation and maintaining hygiene throughout the cutting process.
Solution Approach 2:
Water acts as an intermediary cleaning agent between the chainsaw blade and foreign substances. The spray system introduces water as a mediating substance that washes away contaminants, preventing direct contact between biological materials and the blade surface, thus eliminating the medium for microorganism growth.
4Manufacturing precision
If a robot tool system is used for automatic bisecting, then work consistency is improved, but the device complexity increases
Solution Approach 1:
The robotic system integrates multiple functions into a single automated platform: the robot arm provides positioning and movement, the chainsaw performs cutting, the spray system maintains hygiene, and the control system coordinates all operations. This multi-functionality reduces the need for separate manual operations and equipment.
Solution Approach 2:
The patent combines the cutting function (chainsaw), positioning function (robot arm), and cleaning function (spray system) into an integrated automated system. By merging these previously separate functions into one coordinated system, the overall complexity is managed through unified control rather than multiple independent systems.
