Solution Overview

Problem

Existing wood panel cutting machines face limitations due to the large distance between crosspieces of the pressing device and the simultaneous presence of suction and aligner devices, which restricts the movement and functionality of these components.

Innovation Solution

The machine design features independent motion for the crosspieces of the pressing device and the suction mouths, allowing for a more compact layout and enhanced movement capabilities, with a pneumatic suction device and a pick and transport unit that includes motorized components for efficient cutting and swarf removal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the suction mouth is mounted between the two crosspieces of the pressing device, then the suction function is integrated, but the distance between crosspieces must be large which increases device complexity

Engineering Contradiction:
Improvesuction function integrationVSAvoiddistance between crosspieces
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The pressing device is divided into two independent systems: the pressing mechanism (crosspieces) and the suction mechanism (suction mouth on carriage). This segmentation allows each component to be optimized independently, eliminating the need for large distance between crosspieces while maintaining suction functionality.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The carriage acts as an intermediary carrier for the suction mouth, decoupling it from the pressing device structure. This intermediary approach allows the suction mouth to be positioned optimally without constraining the crosspiece distance, resolving the contradiction between integration and complexity.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If the aligner device and suction mouth are simultaneously present in the pressing device, then both functions are available, but their strokes are greatly limited

Engineering Contradiction:
Improvemultiple functions availabilityVSAvoidstroke length
Core Design Contradiction:
Adaptability or versatilityVSLength of moving object

Solution Approach 1:

The aligner device and suction mouth are segregated into different structural systems. The aligner device is integrated with the pressing crosspieces while the suction mouth is mounted on the independent carriage, allowing each to achieve its required stroke length without mutual interference.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The suction mouth is moved from the vertical pressing dimension to the horizontal carriage dimension. This dimensional transition allows the suction mouth to operate independently in the horizontal plane while the aligner device operates in the vertical pressing plane, eliminating stroke limitations.

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

3Reliability

If the suction mouth moves with the same law of motion as the cutting device, then synchronized operation is achieved, but the device structure becomes more complex

Engineering Contradiction:
Improvesynchronized operationVSAvoidmotion linkage structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The carriage is equipped with sensors that detect the position of the cutting device, and this position information is fed back to the carriage control system. This feedback mechanism enables the suction mouth to automatically synchronize its movement with the cutting device without requiring complex mechanical linkages.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The mechanical coupling between the cutting device and suction mouth is replaced with an independent carriage system controlled by electronic feedback. This substitution eliminates complex mechanical motion linkages while maintaining synchronized operation through control system coordination.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
