Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for processing food products within single-use containers lack effective mechanisms for preventing reuse and ensuring tamper evidence, particularly in automated and computerized processing environments.
Innovation Solution
A container system featuring a cup closure with a reuse inhibiting portion that changes operative orientations upon processing, providing both human and machine sensible indications of previous use, and a rotatable blade with dynamic sealing capabilities for secure engagement with a drive shaft, ensuring tamper evidence and preventing re-use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a cup closure is designed to be reusable, then ease of operation is improved, but reliability deteriorates due to inability to prevent reuse
Solution Approach 1:
The cup closure is designed with a dynamic reuse inhibiting portion that changes orientation based on processing engagement. The portion has multiple operative orientations (first, second, third, and fourth) that dynamically transition during engagement with the container contents processor, enabling the closure to adapt its state based on processing status while maintaining operational ease during legitimate use.
Solution Approach 2:
The invention employs visual indicators (analogous to color changes) through the reuse inhibiting portion's different operative orientations. The portion provides human sensible indications and machine sensible indications of previous use through its orientation changes, making the reuse status visually detectable without requiring complex electronic systems.
2Reliability
If a container system includes complex reuse prevention mechanisms, then reliability is improved, but device complexity increases
Solution Approach 1:
The reuse inhibiting portion is integrated directly into the cup closure structure, merging the tamper-evident functionality with the closure itself. This eliminates the need for separate complex prevention mechanisms, electronic sensors, or additional components, achieving reliable tamper evidence through a unified mechanical design.
Solution Approach 2:
The cup closure automatically provides tamper evidence and reuse prevention through its own structural changes during processing engagement. The reuse inhibiting portion self-activates and self-indicates through orientation changes, eliminating the need for external monitoring systems or complex control mechanisms.
3Reliability
If a cup closure provides machine sensible indications of previous use, then reliability is improved, but ease of operation deteriorates due to reduced user flexibility
Solution Approach 1:
The reuse inhibiting portion dynamically transitions between orientations based on processing engagement, automatically providing machine sensible indications without requiring user intervention. The system self-regulates the indication state based on whether the closure is engaged with the processor, maintaining user flexibility while ensuring reliable detection.
