Layered Beverage Tablet Structure for Strength Without Packaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional compacted beverage tablets have low tensile strength, leading to issues during storage and transportation, and they often require individual packaging that contributes to waste.
Innovation Solution
The beverage tablets are designed with specific ingredient positioning and layering, such as lighter roast coffee in the inner portion and darker roast coffee in the outer portion, along with varying concentrations of binding agents and filter aids, to enhance tensile strength and reduce breakage, while being package-less for direct use in beverage machines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional compacted beverage tablets are used, then they can be stored and transported, but they have low tensile strength leading to breakage
Solution Approach 1:
The patent applies local quality by creating distinct inner and outer portions with different compositions. The outer portion contains higher concentrations of binding agents and filter aids, providing enhanced structural strength and breakage resistance at the periphery, while the inner portion focuses on flavor content. This localized differentiation resolves the contradiction by strengthening specific areas without compromising the overall tablet function.
Solution Approach 2:
The patent employs composite materials by combining multiple ingredients with different properties in a single tablet structure. The outer portion uses binding agents (such as starch or cellulose) and filter aids (such as perlite or diatomaceous earth) to create a stronger, more durable outer shell that protects the inner flavor-containing portion during storage and transportation.
2Reliability
If individual packaging is used for beverage tablets, then protection during transit is improved, but waste is increased
Solution Approach 1:
The patent applies self-service by designing the tablet itself to provide the protection function that would otherwise require separate packaging. The enhanced outer portion with binding agents and filter aids acts as a self-contained protective shell, eliminating the need for individual packaging while maintaining protection during transit and storage.
Solution Approach 2:
The patent makes the tablet multi-functional by giving the outer portion dual roles: it serves as both the structural protective shell and the filter medium for beverage preparation. This eliminates the need for separate packaging materials, as the tablet itself provides both protection and filtration functions.
3Manufacturing precision
If lighter roast coffee is used in the inner portion, then flavor quality is improved, but tensile strength decreases
Solution Approach 1:
The patent applies local quality by placing lighter roast coffee (which provides superior flavor) in the inner portion where it is protected by the stronger outer shell. The outer portion contains darker roast coffee and higher concentrations of binding agents, providing structural strength. This spatial differentiation allows the inner portion to optimize for flavor without compromising overall tablet strength.
