Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional shredding machines are used, then plastic containers can be processed, but the flakes produced are not uniform in size and shape
Solution Approach 1:
The cutting mechanism is segmented into multiple blades arranged in a matrix pattern on the fixed plate, with corresponding blades on the movable plate. This segmentation allows simultaneous cutting at multiple points, producing uniform flakes while maintaining high processing speed
Solution Approach 2:
The movable plate with blades moves dynamically toward the fixed plate during operation, creating a dynamic cutting action that ensures consistent flake size. The movement allows the blades to crash through the container material uniformly, achieving both precision and efficiency
2Reliability
If basic shredding function is provided, then container processing is possible, but material identification and safety features are lacking
Solution Approach 1:
Sensors are integrated to detect material properties before the shredding action begins. This preliminary detection allows the system to identify material type and adjust operating parameters, enhancing safety and reliability without requiring complex post-processing systems
Solution Approach 2:
The machine integrates multiple functions including material detection, safety monitoring, and shredding operations into a single unified system. The sensor array and control system serve multiple purposes: identifying material type, detecting anomalies, and coordinating the shredding process, thereby improving reliability without proportionally increasing complexity
3Ease of operation
If manual operation is used, then the machine is simple to operate, but user engagement and incentive mechanisms are absent
Solution Approach 1:
The system incorporates feedback mechanisms through sensors that detect container presence, material type, and processing status. This feedback is communicated to users through the interface, providing real-time information about the shredding process and enabling incentive mechanisms based on verified recycling activity, while maintaining simple operation
Solution Approach 2:
The machine automatically performs material identification and processing verification without requiring complex user input. The system self-monitors the shredding process and automatically tracks recycling metrics for incentive purposes, keeping the user interface simple while enabling sophisticated engagement and reward mechanisms

AI summary
A machine for shredding plastic container including a pressing device having a main housing having an interior space, a first opening for feeding container and a second opening for disposing the shredded pieces, a fixed plate position at one end within the housing and having slits arranged in matrix pattern, facing the interior of the housing, and having sharp edges, a movable plate having plurality of blades connected to at least one arm. The movable plate can move along a central axis within the housing and the blades have edges facing the sharp edges of the fixed plate. The containers are placed between the plates, such that when the movable plates moves along the central axis of the housing toward the fixed plate, the blades crash and cut the container into flakes. Pegs protrude from the blades, such that when the arm moves forward, the pegs punch the container.
