Solution Overview

Problem

Existing beverage and foodstuff preparation systems face limitations in encoding preparation information due to low encoding density, visibility, and aesthetic concerns of existing codes on containers.

Innovation Solution

A container with a high encoding density code comprising a reference portion and a data portion, where the data portion includes a plurality of adjacent sectors on a circular encoding line, allowing for efficient image processing using a Polar coordinate system, and enabling the encoding of various preparation parameters without being overly visible.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If a code is arranged on the container to encode preparation information, then the preparation information can be read by the machine to optimise the preparation process, but the encoding density is limited and the code is highly visible which may be considered aesthetically displeasing

Engineering Contradiction:
Improveencoding densityVSAvoidvisibility
Core Design Contradiction:
Loss of informationVSObject-affected harmful factors

Solution Approach 1:

The patent transitions from linear/sequential code arrangements to a two-dimensional polar coordinate system. The code is organized with concentric circles representing different parameters and radial lines representing different values, allowing much higher information density in a compact circular area while maintaining aesthetic appeal through symmetric geometric patterns.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The patent employs a circular encoding layout with concentric circles and radial lines instead of linear arrangements. This curved/geometric organization allows efficient use of space, higher encoding density, and creates an aesthetically pleasing symmetric pattern that is less obtrusive on the container surface.

Inventive Principle:
Principle #14Spheroidality (Curvature)

2Loss of information

If a code with high encoding density is implemented, then more preparation information can be encoded, but the code may become more complex and difficult to produce

Engineering Contradiction:
Improveencoding densityVSAvoidcode production complexity
Core Design Contradiction:
Loss of informationVSEase of manufacture

Solution Approach 1:

The code is segmented into distinct functional components: concentric circles represent different parameters (temperature, pressure, time, etc.) while radial lines represent different values. Each intersection point encodes specific information. This segmentation allows systematic organization of multiple parameters without creating overall complexity, making the code both high-density and manufacturable.

Inventive Principle:
Principle #1Segmentation

3Adaptability or versatility

If a code encodes parameters with wide numerical ranges, then more preparation information can be stored, but the code structure becomes more complex requiring more symbols

Engineering Contradiction:
Improveparameter rangeVSAvoidcode structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent uses the position (radial distance from center) and angular position of markers to encode numerical values. By changing the parameters of marker positions rather than using different symbol types or increasing symbol count, the system can represent wide numerical ranges efficiently. The polar coordinate system naturally accommodates continuous or discrete value ranges through positional variation.

Inventive Principle:
Principle #35Parameter changes
