Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual peeling and cutting methods are used, then simplicity and low cost are maintained, but productivity and processing efficiency are low
Solution Approach 1:
The machine is divided into distinct functional modules: a crown and base cutting system with horizontal blades, a peeling system with vertical blades, and a final processing system. Each module handles a specific stage of pineapple processing, allowing independent optimization and maintenance while achieving high overall productivity through automated sequential operations.
2Productivity
If automated processing systems are implemented, then productivity is improved, but device complexity increases
Solution Approach 1:
The machine incorporates adjustable horizontal blades for crown and base cutting, and adjustable vertical blades for peeling, allowing a single device to handle multiple processing stages. The adjustable nature of the blades enables adaptation to different pineapple sizes and processing requirements, reducing the need for multiple specialized machines while maintaining high productivity.
3Reliability
If gripping force is increased to secure pineapple handling, then reliability of handling is improved, but juice extraction from fruit increases
Solution Approach 1:
The gripping means applies force locally at specific contact points on the pineapple surface rather than distributing pressure across the entire fruit. This localized gripping approach secures the pineapple during transport between processing stages while minimizing compression that would cause juice extraction, maintaining both handling reliability and fruit quality.
4Manufacturing precision
If blade height is fixed for precise cutting, then manufacturing precision is improved, but adaptability to different pineapple sizes decreases
Solution Approach 1:
The horizontal and vertical blades are designed with adjustable height mechanisms, allowing the cutting and peeling depths to be dynamically modified according to the size of the pineapple being processed. This dynamic adjustability maintains precise cutting quality across different fruit sizes without requiring multiple sets of fixed blades, combining precision with versatility.

Implementation Method 1
a pneumatic gripper having in turn two parallel opening arms and a 'V' shaped claw attached to the end of each arm
Implementation Method 2
the gripping means have a pneumatic linear actuator on which said pneumatic gripper is fixed, so that it can be moved along the linear cutting path
Implementation Method 3
a crown cutting blade and a base cutting blade of the pineapple, both horizontal blades, and arranged in the cutting path of the gripping means
Implementation Method 4
a cylindrical cutting tube arranged vertically, for vertically holding the pineapple which has been positioned therein by the movable gripping means, and cutting or peeling its outer skin
