Solution Overview
Problem
Current methods for separating sepals and calyces from the central seed capsule of the Roselle plant are wasteful and labor-intensive, leading to inefficiencies in production and increased costs.
Innovation Solution
An automated cutting apparatus featuring a two-prong system, air blower, and motor-driven cutting mechanism that separates the sepals from the seed capsule, utilizing the weight difference to facilitate efficient separation and collection of sepals and seed capsules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual separation method is used, then labor cost is high and production speed is low, but material loss is minimal
Solution Approach 1:
The device segments the sorrel calyx into two distinct parts: the seed capsule and the sepals. By using a cutting blade that divides the calyx at the attachment point, the system achieves clean separation without damaging the sepals, thus eliminating material loss while enabling automated high-speed processing
Solution Approach 2:
An air blower acts as an intermediary force to separate and direct the cut components. The air stream blows the lighter sepals away from the heavier seed capsules, enabling automatic separation and collection of different parts without manual intervention, thereby increasing productivity while preserving all materials
2Productivity
If automated cutting apparatus is used, then productivity increases and labor is reduced, but device complexity increases
Solution Approach 1:
The device feeds itself through gravity-assisted material flow. Uncut sorrel calyces are fed into the cutting chamber where they are automatically positioned and processed. The air blower system also self-regulates by directing cut parts to appropriate collection areas, minimizing the need for complex control mechanisms while maintaining high productivity
Solution Approach 2:
The system uses a simple pneumatic system with an air blower to achieve separation of cut components. This pneumatic mechanism provides automated sorting and ejection of sepals and seed capsules without requiring complex mechanical arms, sensors, or control systems, thus maintaining device simplicity while enabling automated operation
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The automated system significantly reduces manual labor and production costs by enabling faster separation of sepals and calyces, increasing yield and reducing waste.
Implementation Method 1
The sepals which carries less weight is blown forward and the sepals go into the exit tray
