Solution Overview

Problem

Existing wood processing systems are complex and pose safety risks due to the need for coordinating multiple components, leading to inefficiencies and increased time before raw parts can be processed, with human interaction contributing to these issues.

Innovation Solution

A compact wood processing system utilizing a rotatable robot with a detection device and gripper to automate the handling and alignment of panel-shaped workpieces within a defined action space, minimizing human intervention and enabling complete enclosure for enhanced safety and efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If multiple components are coordinated to process workpieces through storage locations, alignment stations, and processing stations, then the processing capability is improved, but the system complexity and processing time increase

Engineering Contradiction:
Improveprocessing capabilityVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent combines multiple previously separate functions (storage, alignment, processing, and handling) into an integrated processing center where a robot arm coordinates all operations. The robot serves as a central coordinator that replaces multiple independent handling systems, merging the functions of feeders, unloaders, and positioning devices into a single automated system.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The robot arm is designed as a universal device that can perform multiple functions: picking workpieces from storage locations, transporting them to alignment stations, loading them onto processing stations, and unloading finished parts. This single multi-functional device replaces what would traditionally require several specialized machines and handlers.

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

2Productivity

If multiple components are coordinated to process workpieces, then the processing capability is improved, but the processing time increases

Engineering Contradiction:
Improveprocessing capabilityVSAvoidprocessing time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The robot arm operates continuously without idle transitions between separate machines. By maintaining a centralized position within the processing center, the robot eliminates the time losses associated with workpieces being transported between independent stations and handlers. The robot can continuously pick, place, and coordinate operations in a streamlined sequence without the delays of inter-machine transfer.

Inventive Principle:
Principle #20Continuity of useful action

3Extent of automation

If human personnel interact with the system for feeding and removing workpieces, then the system requires less automation, but safety risks and inefficiency increase

Engineering Contradiction:
Improveautomation levelVSAvoidsafety risks
Core Design Contradiction:
Extent of automationVSObject-affected harmful factors

Solution Approach 1:

The processing center is designed as a self-sufficient automated system where the robot arm independently performs all workpiece handling operations. The system feeds itself by having the robot pick workpieces from storage, position them for processing, and remove finished parts without requiring external human intervention. This self-service capability eliminates safety risks associated with human operators working within the processing zone.

Inventive Principle:
Principle #25Self-service

4Object-affected harmful factors

If a compact system design is implemented with all components within robot reach, then the system can be fully enclosed for safety, but the installation space is reduced

Engineering Contradiction:
ImprovesafetyVSAvoidinstallation space
Core Design Contradiction:
Object-affected harmful factorsVSArea of stationary object

Solution Approach 1:

The patent arranges storage locations, alignment stations, and processing stations in a nested or compact radial configuration around the robot arm's base. Components are positioned within the robot's maximum reach radius, creating a tightly integrated circular footprint. This nested arrangement allows all necessary components to fit within a compact enclosed space while maintaining full accessibility for the robot arm.

Inventive Principle:
Principle #7Nested doll (Nesting)
