Solution Overview

Problem

Existing diagonal saw systems for panel-shaped products face challenges in achieving high production speeds and cycle rates within limited installation space, leading to increased system costs and complexity, with insufficient redundancy for reliable operation.

Innovation Solution

A device with multiple saw carriages on a shared rail, allowing for simultaneous and alternating operation, reducing the need for multiple frames, suction systems, and control units, while enabling safe blade changes and efficient cutting of short panels, with the option to arrange saws above or below the panel strand.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If multiple diagonal saws are arranged in separate frames to increase cutting capacity and reduce cycle time, then productivity increases, but device complexity and installation space requirements increase

Engineering Contradiction:
Improvecutting capacityVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent combines multiple diagonal saws (at least two) onto a single shared rail structure, merging what would traditionally be separate frames into one integrated system. This reduces the number of independent frames, suction systems, and control units needed, thereby decreasing device complexity while maintaining high cutting capacity through simultaneous and alternating operation of multiple saws

Inventive Principle:
Principle #5Merging (Combining)

2Productivity

If multiple diagonal saws are arranged in separate frames to reduce cycle time, then productivity increases, but installation space increases

Engineering Contradiction:
Improvecycle timeVSAvoidinstallation space
Core Design Contradiction:
ProductivityVSArea of stationary object

Solution Approach 1:

By merging multiple saws onto a single shared rail, the patent consolidates the spatial footprint of multiple separate frames into one compact structure. This reduces the overall installation space required while enabling simultaneous and alternating cutting operations that maintain short cycle times for high-speed production

Inventive Principle:
Principle #5Merging (Combining)

3Manufacturing precision

If single saws are used for long panels or slow feed speeds, then manufacturing precision is maintained, but productivity decreases

Engineering Contradiction:
Improvecutting precisionVSAvoidfeed speed
Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

The patent employs alternating operation of multiple saws where saws are used in sequence - while one saw is cutting, another can be positioned or prepared. This periodic alternation enables high feed speeds for thin panels by distributing the cutting workload across multiple saws while maintaining precision through controlled, sequential operation

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The system dynamically selects which saw operates based on panel thickness and feed speed requirements. For thick panels requiring slow feed, one saw operates at a time for precision; for thin panels at high feed speeds, multiple saws alternate operation to maintain both speed and cutting quality

Inventive Principle:
Principle #15Dynamics

4Reliability

If redundant saws are added to ensure continuous operation, then reliability increases, but device complexity increases

Engineering Contradiction:
Improveoperational reliabilityVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent achieves redundancy by integrating multiple saws into a single coordinated system on one rail. If one or two saws fail, the remaining saws can continue operation because they share common infrastructure (rail, control, suction), providing fault tolerance without requiring separate redundant frames and systems, thus improving reliability while minimizing complexity increase

Inventive Principle:
Principle #5Merging (Combining)

AI summary

The device has a diagonal sawing mechanism consisting of frames (13) arranged on both sides of plate strings (1), and a slide rail (4) connected to the frames. Displaceable saw carriages (2, 3) with a height adjustable separating equipment (17) is arranged on the slide rail of the sawing mechanism. The saw carriages are arranged on a side of the slide rail. The saw carriages comprise process drives, which work independent of each other. The separating equipment of the saw carriages on the side of the diagonal sawing mechanism works on different dividing lines (9).
