Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing beverage and foodstuff preparation systems face limitations in encoding density, visibility, and aesthetic appeal of codes on containers, which restrict the amount of preparation information that can be encoded and processed efficiently.
Innovation Solution
A container with a code comprising a reference portion and a data portion, using a Polar coordinate system with a semi- or fully circular encoding line intersecting a linear reference line, allowing for high encoding density and efficient image processing, and enabling the encoding of various preparation parameters without being overly visible.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a linear code sequence is printed on the capsule periphery, then the code can be read by the machine, but the encoding density is limited and the code is highly visible
Solution Approach 1:
The patent transitions from a linear one-dimensional code arrangement to a two-dimensional polar coordinate system. The code is arranged with data units positioned at specific radial distances and angular positions around a central reference point, enabling much higher encoding density within the same physical space while maintaining machine readability through systematic geometric organization.
Solution Approach 2:
The patent employs a circular encoding line arranged at a fixed radial distance from a central reference point. This curved, circular arrangement allows the code to be compact and space-efficient compared to linear arrangements, while the circular geometry provides natural rotational symmetry that facilitates machine reading from any orientation.
2Adaptability or versatility
If more preparation information is encoded on the container, then the machine can optimise the preparation process, but the code becomes more complex and visible
Solution Approach 1:
The patent assigns specific meanings to different spatial positions within the polar code structure. Different radial distances and angular positions encode different types of preparation information (temperature, pressure, time, etc.). This local differentiation allows multiple parameters to be encoded in a compact, organized manner without requiring a single complex symbolic sequence.
3Loss of information
If a high encoding density code is used, then more preparation information can be stored, but the code processing becomes more difficult and expensive
Solution Approach 1:
The polar coordinate system serves multiple functions simultaneously: it provides high encoding density, enables rotation-invariant reading (the code can be read from any rotational position), offers natural error detection through geometric constraints, and allows for scalable information capacity. This universal geometric framework simplifies the overall processing requirements compared to high-density linear codes.

AI summary
A container for a beverage or foodstuff preparation machine, the container for containing beverage or foodstuff material and including a code encoding preparation information. The code includes a reference portion and a data portion. The reference portion has reference units defining a reference liner, and the data portion has a data unit. The data unit is arranged on an encoding line D that intersects the reference line r, and the data unit is arranged a distance d from the intersection as a variable to at least partially encode a parameter of the preparation information. The encoding line D is circular and is arranged with a tangent thereto orthogonal the reference liner at the intersection point. The reference units are arranged with a configuration defining a reference point from which the reference line r extends.
