Solution Overview

Problem

Existing processing machines for flat material parts face inefficiencies in the feeding and unloading processes, particularly in turning and positioning wide sheets, which slows down the overall processing speed and requires significant opening of clamping cheeks.

Innovation Solution

A processing machine design featuring a transfer table and a placement unit with side insertion and turning capabilities, allowing for external feeding and turning of flat components without extensive cheek opening, utilizing suction cups connected to a parallelogram mechanism for efficient movement and alignment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a turning unit with suction cups is used to accelerate feeding and turning of flat material parts, then the feeding process is accelerated, but the machine structure becomes more complex and requires additional space for cheek opening

Engineering Contradiction:
Improvefeeding process speedVSAvoidmachine structure complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The placement unit is designed to perform multiple functions: it serves as both a holding device with suction cups for gripping flat material parts and as a turning unit that rotates the material. By integrating these functions into a single multi-functional unit, the patent avoids adding separate complex mechanisms while still achieving accelerated feeding and turning operations.

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

Solution Approach 2:

The patent combines the holding function (suction cups) and the turning function into a single integrated placement unit. This merging of functions reduces the number of separate components needed and simplifies the overall machine structure while maintaining the productivity benefits of both holding and turning capabilities.

Inventive Principle:
Principle #5Merging (Combining)

2Adaptability or versatility

If the cheeks are moved far apart to accommodate turning of wide flat material parts, then wide sheets can be turned over, but the machine opening requirement increases and processing time is extended

Engineering Contradiction:
Improvecapability to handle wide sheetsVSAvoidcheek opening time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The placement unit is designed with movable components that can dynamically adjust their position. The turning unit can rotate and reposition the flat material parts without requiring the cheeks to be permanently or extensively opened, allowing the cheeks to return to a closer position after the turning operation, thus reducing processing time.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

Instead of requiring increased lateral separation of the cheeks to accommodate wide sheets, the patent uses a turning unit that operates in a rotational dimension. This allows wide sheets to be turned over by rotating them around an axis, utilizing vertical and rotational space rather than requiring extended horizontal cheek separation.

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

3Device complexity

If a traditional feeding mechanism is used, then the machine structure remains simple, but the feeding and unloading processes are slow

Engineering Contradiction:
Improvemachine structure simplicityVSAvoidfeeding and unloading speed
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The placement unit with suction cups enables automated gripping, holding, and turning of flat material parts without requiring manual intervention. The system serves itself by automatically positioning and manipulating the material through the integrated turning unit, thereby increasing feeding and unloading speed while maintaining relatively simple machine structure.

Inventive Principle:
Principle #25Self-service
