Rotatable Marking Elements for Log Code Variability

Solution Overview

Problem

Existing marking devices for applying code markings on logs lack variability and efficiency, making it difficult to quickly and simply identify logs during the harvesting process, which is essential for tracking origin, quality, and movement.

Innovation Solution

A marking device with adjustable marking members, including rotatable marking elements that can be set to different rotational positions, allowing for varied code markings on the end surface of logs, enhancing the marking device's variability and efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional marking devices are used, then the marking process is simple, but the variability of code markings is limited

Engineering Contradiction:

Improvevariability of code markingVSAvoidmarking device structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The marking device is divided into multiple independent marking members (at least three), each capable of being independently positioned. This segmentation allows each marking member to contribute to different aspects of the code marking, thereby increasing variability without requiring a complete redesign of the entire marking system.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The marking members are made adjustable and movable between different positions. At least one marking member is rotatable around an axis, allowing dynamic reconfiguration of the marking pattern. This dynamic capability enables the same physical device to produce varied code markings by changing the spatial arrangement and rotational positions of its components.

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If marking members are made adjustable, then code marking variability improves, but device complexity increases

Engineering Contradiction:

Improvecode marking variationVSAvoidmarking member adjustment mechanism

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The marking members are made adjustable and movable between different positions. At least one marking member is rotatable around an axis, allowing dynamic reconfiguration of the marking pattern. This dynamic capability enables the same physical device to produce varied code markings by changing the spatial arrangement and rotational positions of its components.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The marking device is designed with marking members that can serve multiple functions: they can be positioned at different locations, rotated to different angles, and configured in various combinations. This multi-functionality allows a single marking device to handle diverse code marking requirements without needing multiple specialized devices.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If rotatable marking elements are added, then marking variability increases, but device complexity and adjustment time increase

Engineering Contradiction:

Improverotational position variabilityVSAvoidmarking preparation time

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The marking members are made adjustable and movable between different positions. At least one marking member is rotatable around an axis, allowing dynamic reconfiguration of the marking pattern. This dynamic capability enables the same physical device to produce varied code markings by changing the spatial arrangement and rotational positions of its components.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The invention changes the positional parameters of the marking members by allowing rotation around axes. By varying the rotational position parameter, the device can generate different code markings. This parameter-based control allows for quick adjustment without physical reconfiguration of the entire marking system.

Inventive Principle:

Principle #35Parameter changes

AI summary

The invention relates to a marking device for applying acode marking on a piece of wood. The marking device comprises several adjustable marking members, each of which comprising a marking element which is capable of applying a mark on a piece of wood and which is shiftable between different positions or states so as to allow a variation of the code marking to be applied by the marking device. At least one of said marking members (170) comprises a rotatable marking element (171), which is arranged to apply a rotationally unsymmetrical mark on a piece of wood and which is settable in different rotational positions in relation to the marking elements of the other marking members. The invention also relates to a harvesting arrangement for tree harvesting comprising such a marking device.
