Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple formulations are held in a single reservoir, then the device can provide multiple sensory experiences, but the formulations react with each other causing degradation and reducing shelf-life
Solution Approach 1:
The patent divides the reservoir into multiple separate cartridges, each containing a single formulation. This segmentation prevents direct contact and chemical reactions between different formulations while allowing the device to hold multiple formulations simultaneously. Each cartridge is independently sealed and can be activated separately through independent connectors and control circuitry.
2Reliability
If multiple formulations are stored separately in separate cartridges, then formulation reactions are prevented, but the device complexity increases with multiple connectors and control systems
Solution Approach 1:
The patent employs universal connector designs that can interface with multiple cartridge types while maintaining the same basic connection protocol. The control circuitry uses a standardized communication interface that can identify and manage different cartridge formulations through a common control architecture, reducing the complexity that would otherwise arise from having entirely separate control systems for each cartridge.
3Ease of operation
If independent control circuitry is implemented for each cartridge, then dispersion generation can be controlled independently, but the manufacturing cost and device complexity increase
Solution Approach 1:
The control circuitry implements periodic activation sequences where cartridges are activated in a controlled, alternating manner rather than continuously. This periodic control allows the system to manage multiple cartridges with simpler timing logic, reducing the complexity of the control circuitry while still providing independent control capability for each cartridge's dispersion generation.
