Compact Laminator with Pivotable Flaps for Dirt Protection
Find Innovative SolutionsGenerate Solutions
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
Engineering 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
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.
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.
2Productivity
If the ejection slot remains open for laminate ejection, then productivity is improved, but dirt ingress increases causing soiling
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.
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.
3Object-affected harmful factors
If flaps are added to close slots, then dirt protection is improved, but device complexity increases
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.
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.
4Object-affected harmful factors
If flaps are closed during non-use, then dirt protection is improved, but accessibility for insertion is reduced
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.

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.
