Solution Overview

Problem

Laminating devices allow dirt to enter through insertion and ejection slots, soiling the laminate and causing technical defects and unsightly results.

Innovation Solution

A laminating device with pivotable front and rear flaps that can be closed to prevent dirt ingress, featuring a support surface for easy item alignment and positioning, and a bearing surface for the laminate to prevent bending and ensure proper cooling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the insertion slot remains open for item insertion, then ease of operation is improved, but dirt ingress increases causing soiling and technical defects

Engineering Contradiction:
Improveitem insertionVSAvoiddirt ingress
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The front flap is made pivotable between an open position (for item insertion) and a closed position (for dirt protection). This dynamic element allows the system to adapt its state based on operational needs, providing both easy access during use and effective sealing when idle.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The front flap acts as an intermediary element between the external environment and the insertion slot. It mediates between the need for item insertion and the need to prevent dirt ingress, allowing controlled access while blocking harmful particles when closed.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If the ejection slot remains open for laminate ejection, then productivity is improved, but dirt ingress increases causing soiling

Engineering Contradiction:
Improvelaminate ejectionVSAvoiddirt ingress
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The rear flap is designed to be pivotable between open and closed positions, enabling quick ejection of laminates while maintaining dirt protection when the device is not in use. This dynamic mechanism ensures both high productivity during operation and effective sealing during idle periods.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The rear flap serves as an intermediary between the ejection slot and the external environment, controlling access while preventing dirt contamination. It allows laminate passage during operation but blocks harmful factors when closed.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Object-affected harmful factors

If flaps are added to close slots, then dirt protection is improved, but device complexity increases

Engineering Contradiction:
Improvedirt protectionVSAvoidstructure
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The sealing function is segmented into two independent flaps (front and rear) that can operate independently. This segmentation allows each flap to be optimized for its specific location and function, simplifying the overall design compared to a single complex sealing mechanism.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The flaps are designed as thin, flexible covering elements that pivot on simple hinges. This approach uses simple geometric forms and flexible materials rather than complex mechanical structures, minimizing the increase in device complexity while achieving effective sealing.

Inventive Principle:
Principle #30Flexible shells and thin films

4Object-affected harmful factors

If flaps are closed during non-use, then dirt protection is improved, but accessibility for insertion is reduced

Engineering Contradiction:
Improvedirt protectionVSAvoidinsertion access
Core Design Contradiction:
Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The flaps are designed to be easily pivotable between closed and open positions. This dynamic characteristic ensures that while the flaps provide dirt protection when closed, they can be quickly opened to provide full insertion access when needed, with no permanent obstruction.

Inventive Principle:
Principle #15Dynamics

AI summary

The laminating device (10) has a housing (12) and a laminating unit for laminating the laminated goods made from sheet material and plastic film to a laminate. The housing has a front flap (18) which is pivoted between a closing position, in which it closes an insertion slot (14), and a laminating position, in which it releases the insertion slot.
