Solution Overview

Problem

The existing panel dividing systems face inefficiencies during scratch cuts, as they generate a large amount of sawdust that needs to be manually removed, leading to increased cycle times and dust exposure for machine operators.

Innovation Solution

Incorporating air nozzles near the dividing line that generate directed air jets parallel to the support table to efficiently transport chips away from the cutting area, reducing the need for manual removal and enhancing the cleanliness of the support table.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If scratch cut is performed with saw blade, then edge processing is achieved, but large amount of sawdust remains on support table requiring manual removal

Engineering Contradiction:
Improvemanual chip removalVSAvoidcycle time
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The patent replaces the manual mechanical chip removal system with a pneumatic system. Air nozzles positioned near the dividing line generate directed air jets that automatically transport chips away from the cutting area, eliminating the need for manual broom or compressed air gun intervention and reducing cycle time.

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

Solution Approach 2:

The chip removal system becomes self-service through the automated pneumatic transport mechanism. The air jets continuously and automatically remove chips from the support table without requiring operator intervention, making the system self-sufficient in maintaining operational efficiency.

Inventive Principle:
Principle #25Self-service

2Object-affected harmful factors

If manual chip removal is performed, then support table is cleaned, but cycle time increases and operator dust exposure increases

Engineering Contradiction:
Improveoperator dust exposureVSAvoidcycle time
Core Design Contradiction:
Object-affected harmful factorsVSLoss of time

Solution Approach 1:

The patent replaces manual chip removal operations with an automated pneumatic system. Air nozzles generate directed air jets that continuously transport chips away from the cutting area, eliminating operator exposure to dust and removing the time loss associated with manual intervention.

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

3Productivity

If air nozzles are arranged in upper side of support table, then chip transport efficiency is improved, but device complexity increases

Engineering Contradiction:
Improvechip transport efficiencyVSAvoidair nozzle arrangement
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent applies local quality by positioning air nozzles specifically in the upper side of the support table in the area of the dividing line, where chip generation occurs. This localized placement optimizes chip transport efficiency precisely where needed without requiring complex system-wide modifications.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent utilizes pneumatic principles by employing air nozzles that generate directed air jets. The pneumatic system efficiently transports chips through controlled air flow, achieving high chip removal effectiveness while maintaining relatively simple device architecture compared to mechanical alternatives.

Inventive Principle:
Principle #29Pneumatics and hydraulics
