Solution Overview

Problem

Current methods for packaging firewood, either in pallets or bunches, face inefficiencies such as high labor costs, space requirements, and waste due to manual handling and limited adaptability for varying quantities and storage conditions.

Innovation Solution

A machine and method for automatically forming parallelepiped-shaped bunches of firewood using a forming unit, cutting unit, and strapping device, which reduces labor costs, optimizes transportation and storage by enabling easy pallet loading, and decreases waste by using a machine that can handle local wood efficiently.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If firewood is packaged in pallets, then large quantities can be supplied efficiently, but users require significant storage space and access infrastructure

Engineering Contradiction:
Improvesupply efficiencyVSAvoidstorage space
Core Design Contradiction:
ProductivityVSArea of stationary object

Solution Approach 1:

The invention segments the firewood supply into modular bunches that can be easily handled and stored in small spaces, while maintaining efficient supply capabilities through standardized packaging dimensions that optimize space utilization

Inventive Principle:
Principle #1Segmentation

2Area of stationary object

If firewood is packaged in manually formed bunches, then storage space requirements are reduced, but labor costs increase significantly

Engineering Contradiction:
Improvestorage spaceVSAvoidlabor automation
Core Design Contradiction:
Area of stationary objectVSExtent of automation

Solution Approach 1:

The packaging machine performs automatic bunch formation, cutting, and strapping operations without manual intervention, allowing the system to serve itself in the packaging process and eliminating the need for manual bunch formation labor

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The invention changes the physical parameters of the bunches by forming them in standardized parallelepiped shapes with specific dimensions, which optimizes both storage efficiency and automated handling capabilities

Inventive Principle:
Principle #35Parameter changes

3Productivity

If pallet packaging is used, then large quantities can be transported efficiently, but manufacturing and disposal costs are relatively expensive

Engineering Contradiction:
Improvetransportation efficiencyVSAvoidpackaging cost
Core Design Contradiction:
ProductivityVSEase of manufacture

Solution Approach 1:

The invention uses simple, inexpensive strapping materials and basic packaging components that can be easily manufactured and disposed of, replacing expensive reusable pallets with cost-effective single-use or limited-use packaging solutions

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

4Adaptability or versatility

If bunches are formed manually, then adaptability to small quantities is improved, but labor waste increases

Engineering Contradiction:
Improvequantity adaptabilityVSAvoidlabor waste
Core Design Contradiction:
Adaptability or versatilityVSLoss of substance

Solution Approach 1:

The packaging system is designed to be dynamic and adaptable, capable of adjusting to different wood log dimensions and quantities while maintaining automated operation, allowing efficient packaging of varying batch sizes without manual intervention

Inventive Principle:
Principle #15Dynamics

AI summary

A method for packaging firewood, comprising the steps of: inserting the wood, in the form of horizontally oriented logs (3), into a container (8) having a rectangular cross-section so as to form a stack (5), cutting the stack (5) at a predetermined height from a bottom surface of the container (8) so as to form a wood bunch (2) with a parallelepiped shape, pushing the bunch (2) out of the container (8) through a side opening (19) thereof, and strapping the bunch (2).
