Exine-Construct Bonding for Substance Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The size limitation of plant-based microcapsules hinders the storage and delivery of larger substances, requiring a vehicle that is both large enough for storage and suitable for protection and delivery, while also addressing issues like premature degradation from external influences.
Innovation Solution
The development of an exine-construct by chemically or physically binding exine shells together to form structures with hollow chambers, allowing for the encapsulation and protection of active substances, which can be used as delivery vehicles and provide protection against degradation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If exine shells are used as individual microcapsules, then they provide protection and delivery capabilities, but their small size limits the storage and delivery of larger substances
Solution Approach 1:
The patent combines multiple exine shells into a single exine-construct by chemical or physical bonding. This merging approach allows the construct to accommodate larger substances while maintaining the protective and delivery capabilities of individual exine shells. The bonded structure creates a larger internal volume for substance storage without sacrificing the functional advantages of exine material.
2Reliability
If exine shells are used to protect active substances, then they prevent degradation from external influences, but they may not provide sufficient protection for large-scale or extended delivery requirements
Solution Approach 1:
By bonding multiple exine shells together, the patent creates a more robust protective structure that can provide extended delivery duration. The combined structure maintains the protective properties of individual shells while offering greater structural integrity and capacity for sustained release over time.
Solution Approach 2:
The patent describes exine shells being combined in nested or layered arrangements to form the exine-construct. This nesting approach allows for multiple layers of protection and creates a structured design that can control substance release over extended periods while maintaining reliability of protection.
3Volume of stationary object
If multiple exine shells are bonded together to form larger structures, then storage capacity increases, but the complexity of forming stable bonds between shells increases
Solution Approach 1:
The patent employs bonding agents or linking molecules as intermediaries to connect exine shells together. These intermediaries facilitate the bonding process by providing chemical or physical attachment points between shells, reducing the complexity of direct shell-to-shell bonding while enabling stable construction of larger structures.
