Solution Overview

Problem

The handling of beam-cut parts cut out of a piece of material is inefficient, with existing technologies experiencing mechanical locking effects between parts and the remainder of the material, which complicates the process and reduces productivity.

Innovation Solution

A table with a rib structure that can lift and hold beam-cut parts in a vertical direction, combined with a gripping robot system that uses grippers to manage and separate the parts, minimizing mechanical locking and enhancing handling efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If traditional handling methods are used for beam-cut parts, then the process is simpler, but mechanical locking effects occur between parts and the remainder of the material, reducing productivity

Engineering Contradiction:
Improvehandling efficiencyVSAvoidtable structure complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The table structure is segmented into multiple independent rib elements that can move individually. Each rib can be independently controlled to lift, hold, or lower parts of the beam-cut material, allowing selective handling without affecting the entire structure. This segmentation enables efficient part separation while maintaining system manageability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The rib structure transitions from a static support table to a dynamic system where ribs can move vertically between different positions. The ribs can be raised to lift parts, positioned to hold them in place, or lowered to release them, providing adaptive control for different handling operations and eliminating mechanical locking effects.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If a static table structure is used, then the device is simpler, but mechanical locking effects prevent efficient part separation

Engineering Contradiction:
Improvepart separation easeVSAvoidrib structure complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The rib structure incorporates vertical movement capability, allowing ribs to transition between lowered and raised positions. This dynamic behavior enables operators to easily separate parts by raising specific ribs to lift them away from the material remainder, then positioning or lowering them as needed, all without increasing overall structural complexity.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The ribs act as intermediary elements between the table surface and the beam-cut parts. By introducing these movable intermediate structures, the system achieves easy part separation through a simple raise-lower-position mechanism, avoiding the need for complex gripping or clamping systems.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Productivity

If parts remain on the table after cutting, then handling is simpler, but mechanical locking effects reduce productivity

Engineering Contradiction:
Improveproduction efficiencyVSAvoidmechanical locking effect
Core Design Contradiction:
ProductivityVSObject-generated harmful factors

Solution Approach 1:

The rib structure enables selective extraction of cut parts from the beam-cut material remainder. By raising individual ribs, specific parts are lifted away from the main material body, eliminating mechanical locking effects and allowing continuous production without waiting for manual separation or complex release mechanisms.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The rib structure is positioned and configured in advance to correspond with the locations of cut parts on the material. This preliminary arrangement allows immediate lifting and separation of parts as soon as cutting is complete, maximizing production efficiency by eliminating any delay in part removal.

Inventive Principle:
Principle #10Preliminary action

4Productivity

If manual handling is used, then equipment complexity is lower, but productivity and consistency are reduced

Engineering Contradiction:
Improvehandling speedVSAvoidautomation system complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The rib structure enables the table system to perform handling operations automatically without external intervention. The ribs can be programmed to raise, hold, lower, and move parts autonomously, increasing handling speed and consistency while maintaining relatively simple equipment architecture compared to fully automated robotic systems.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical handling with an automated rib positioning and movement system. This substitution increases productivity and consistency by eliminating human variability and fatigue, while the rib-based mechanism remains mechanically simple and easy to control through basic actuation systems.

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