Multilayer Edible Carrier with Nested Soft and Brittle Shells
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current culinary appliances lack the capability to efficiently produce edible multilayer food carriers with distinct textures and structural integrity for holding fillings, as they either lack the necessary textural diversity or durability to maintain freshness and crunchiness during consumption.
Innovation Solution
A system comprising a dual-cavity assembly with heating elements and actuators that cook two types of batters into soft and brittle edible shells, which are then nested to form a multilayer carrier with a soft inner shell and a brittle outer shell, providing structural integrity and textural contrast.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single-layer food carrier is used, then the preparation process is simple, but the structural integrity and textural diversity are insufficient
Solution Approach 1:
The food carrier is divided into multiple distinct layers (crispy outer layer, soft inner layer, and optional filling layer) that are prepared separately and then assembled. Each layer is cooked in dedicated cavities within the mold assembly, allowing independent control of cooking parameters for each layer to achieve desired textural properties while maintaining overall structural integrity.
Solution Approach 2:
The mold assembly uses nested cavities where an inner cavity receives batter to form the soft inner layer, which is then nested within an outer cavity that receives additional batter to form the crispy outer layer. This nested structure allows the softer layer to be enclosed within the crispier layer, creating a multi-textural carrier that maintains both structural integrity and textural diversity.
2Device complexity
If a single-layer food carrier is used, then the preparation process is simple, but the ability to hold fillings throughout a meal is limited
Solution Approach 1:
The carrier structure is segmented into a crispy outer layer providing structural support and a soft inner layer providing containment. This segmentation creates a hierarchical structure where the outer layer maintains shape and the inner layer secures fillings, enabling reliable holding of fillings throughout the meal while keeping the preparation process manageable through systematic layer-by-layer construction.
Solution Approach 2:
The food carrier uses composite material properties by combining different batter formulations (one yielding crispy texture, another yielding soft texture) into a single multi-layer structure. This composite approach leverages the complementary properties of different materials to achieve both structural integrity for holding fillings and textural diversity, while the systematic preparation process keeps complexity manageable.
3Device complexity
If conventional heating methods are used, then the equipment is simple, but the textural contrast between crispy and chewy layers cannot be achieved
Solution Approach 1:
The heating system is segmented into multiple independently controllable heating zones corresponding to the different layers. The outer cavity has its own heating elements and temperature control, while the inner cavity has separate heating elements. This segmentation allows different temperature profiles to be applied to different layers simultaneously, enabling the crispy outer layer to be cooked at higher temperatures for crunchiness while the inner layer is cooked at lower temperatures for chewiness, achieving textural diversity without requiring overly complex equipment.
Solution Approach 2:
The heating system incorporates dynamic temperature control where the temperature profiles of different heating zones can be adjusted independently during the cooking process. The outer cavity temperature can be elevated to create crispy textures, while the inner cavity maintains lower temperatures for soft, chewy textures. This dynamic adjustability allows a single equipment system to produce multiple textural characteristics by adapting heating parameters rather than requiring multiple specialized appliances.
4Stability of the object's composition
If moisture is present in the food carrier, then the food remains fresh, but the crunchiness of the outer layer is compromised
Solution Approach 1:
The carrier structure is segmented into distinct moisture barriers - the crispy outer layer acts as an external moisture barrier protecting the filling, while the soft inner layer serves as an internal moisture barrier containing the filling. This segmentation creates multiple protective layers that prevent moisture migration between the filling and the crispy outer layer, preserving both freshness and crunchiness. The physical separation of moisture-containing layers prevents degradation of the crispy texture while maintaining overall food freshness.
Solution Approach 2:
The soft inner layer is extracted as a separate moisture-containing component that is nested within the crispy outer layer. By extracting the moisture-containing function into a dedicated inner layer, the crispy outer layer is protected from direct exposure to moisture that would compromise its crunchiness. This extraction allows the outer layer to maintain its crispy properties while the inner layer handles moisture containment, preserving both freshness and textural integrity.

AI summary
One variation of a method for preparing a foodstuff includes: loading a first batter into a first cook chamber; inserting a first core insert into the first cook chamber to form a first thin-shell cavity of a first geometry; heating the first chamber to cook the first batter into a brittle edible shell of the first geometry; loading a second batter into a second cook chamber; inserting a second core insert into the second cook chamber to form a second thin-shell cavity approximating the first geometry; heating the second chamber to cook the second batter into a soft edible shell approximating the first geometry; applying a binding promoter to the soft edible shell; nesting the soft edible shell inside of the brittle edible shell to form a multilayer edible carrier; and loading a set of fillings into the multilayer edible carrier to complete a foodstuff.
