Solution Overview

Problem

Existing systems for preparing filled biscuits are limited in filling options due to the need for thermostable fillings that do not alter during the baking process, restricting the types of fillings that can be used.

Innovation Solution

A system that forms biscuit bodies with cavities and injects a filling through needles after baking, allowing for a variety of fillings to be used without the need for thermostability, featuring a forming unit, conveying system, oven, and injection unit with needles for precise filling placement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If filling is deposited onto planar biscuit bodies or into cavities before baking, then the biscuit structure is formed with filling integrated, but the filling must be thermostable and cannot be altered by baking, severely limiting filling options

Engineering Contradiction:

Improvefilling optionsVSAvoidfilling thermostability

Core Design Contradiction:

Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The process is segmented into distinct stages: biscuit body formation and baking is separated from filling deposition. The biscuit is baked first to achieve structural stability, then filled afterward to allow any filling type to be used without thermostability constraints. This temporal segmentation resolves the contradiction between filling versatility and thermostability requirements.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The biscuit body is prepared in advance with cavities formed before filling. The biscuit structure is fully baked and stabilized beforehand, creating a ready receptacle that can accommodate any filling type without requiring the filling itself to be thermostable. This preliminary preparation of the container structure enables subsequent flexible filling options.

Inventive Principle:

Principle #10Preliminary action

2Adaptability or versatility

If filling is injected into baked biscuit bodies through needles, then diverse fillings can be used without thermostability requirements, but the system complexity increases with injection units and needle mechanisms

Engineering Contradiction:

Improvefilling varietyVSAvoidinjection system complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The complex mechanical needle injection system is replaced with a simpler deposition mechanism. Fillings are deposited onto the biscuit surface or into cavities using gravity-assisted flow or simple pumping systems rather than high-pressure needle injection. This substitution maintains filling versatility while significantly reducing system complexity.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

A simplified intermediary deposition system is introduced between the filling source and the biscuit. Instead of direct needle injection, fillings are delivered through controlled flow channels or hoppers that guide the filling into cavities or onto surfaces. This intermediary mechanism reduces complexity while preserving the ability to deliver diverse filling types.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Shape

If biscuits are baked with filling already inside, then the filling is contained within the biscuit structure, but the filling must remain stable during high-temperature baking, restricting filling choices to thermostable materials only

Engineering Contradiction:

Improvefilling containmentVSAvoidfilling type selection

Core Design Contradiction:

ShapeVSAdaptability or versatility

Solution Approach 1:

The conventional sequence is inverted: instead of filling then baking, the process follows baking then filling. This inversion allows the biscuit structure to be fully formed and stabilized first, then any type of filling (thermally sensitive or not) can be added afterward. The containment function is achieved post-baking, enabling unrestricted filling selection.

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The temperature parameter is changed through time: high temperature during biscuit baking to achieve structural stability, then low or ambient temperature during filling deposition to preserve filling integrity. This temporal parameter change allows the same biscuit structure to accommodate both thermal processing requirements and sensitive filling materials.

Inventive Principle:

Principle #35Parameter changes
