Solution Overview

Problem

Conventional sawmills require large spaces, incur high transportation costs, and have high staffing requirements, with sawn boards prices being arbitrarily dictated by a near-monopoly, posing incalculable risks for timber construction companies and consumers.

Innovation Solution

A woodworking device with integrated edging, cutting, and splitting capabilities on a single processing portal, allowing logs to be processed in a space-saving, efficient, and automated manner, minimizing transportation and labor needs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If multiple separate processing stations are used for edging, cutting, and splitting round timber, then each processing step can be performed with dedicated equipment, but the space requirement increases significantly and transportation costs rise due to moving processed wood between stations

Engineering Contradiction:
Improvededicated processing equipmentVSAvoidspace requirement
Core Design Contradiction:
Ease of manufactureVSArea of stationary object

Solution Approach 1:

The patent combines edging device (5), cutting device (6), and splitting device (7) into a single integrated processing portal (3) that can perform multiple processing steps sequentially on round timber without requiring separate processing stations. This merging of functions directly reduces the space requirement while maintaining dedicated processing capabilities for each operation.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The processing portal (3) is designed as a universal platform that can perform multiple different processing operations (edging, cutting, splitting) on the same round timber through different devices arranged on it. This multi-functionality eliminates the need for multiple separate processing stations, thereby reducing space requirements and transportation needs.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Ease of manufacture

If multiple separate processing stations are used for timber processing, then each operation can be optimized with specialized machinery, but staffing requirements increase due to the need to operate multiple separate machines

Engineering Contradiction:
Improvespecialized processing capabilityVSAvoidstaffing requirements
Core Design Contradiction:
Ease of manufactureVSEase of operation

Solution Approach 1:

By merging edging device (5), cutting device (6), and splitting device (7) into one processing portal (3), the system reduces the number of separate machines that need to be operated. A single operator can control all processing operations through the integrated portal, significantly reducing staffing requirements compared to operating multiple separate processing stations.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The universal processing portal (3) performs multiple specialized operations (edging, cutting, splitting) that would otherwise require separate specialized machines. This consolidation allows one operator to manage all specialized processing functions, reducing the need for multiple staff members while maintaining optimized processing capabilities.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Productivity

If round timber is processed in a single integrated portal, then space requirements are reduced and processing efficiency increases, but the device complexity increases due to integrating multiple processing functions

Engineering Contradiction:
Improveprocessing efficiencyVSAvoidintegrated processing system
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The processing portal (3) is divided into distinct functional segments: edging device (5) with milling heads, cutting device (6) with horizontally oriented saws, and splitting device (7) with vertically oriented saws. Each segment performs a specific function, making the complex integrated system manageable through modular segmentation while maintaining high processing efficiency.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The processing portal (3) is arranged in a longitudinal configuration along the round timber, with processing devices positioned at different locations along the length of the timber. This spatial arrangement in the longitudinal dimension allows multiple processing operations to be performed sequentially without requiring complex vertical stacking or overlapping operations, thereby managing device complexity while maintaining productivity.

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

4Ease of manufacture

If conventional sawmills are used for processing round timber, then processed wood can be produced with established machinery, but transportation costs increase and price risks arise due to monopoly control

Engineering Contradiction:
Improveestablished processing machineryVSAvoidtransportation costs
Core Design Contradiction:
Ease of manufactureVSQuantity of substance

Solution Approach 1:

The patent extracts the essential processing functions (edging, cutting, splitting) from the conventional sawmill environment and consolidates them into a single portable processing portal (3). This extraction eliminates the need for expensive transportation of processed wood to and from centralized sawmills, as processing can be performed on-site or in smaller decentralized locations, thereby reducing transportation costs while using established processing machinery.

Inventive Principle:
Principle #2Taking out (Extraction)
