Portable Laminator Double-Walled Housing and Dust Cover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing office laminators are not designed for portability or storage, leading to exposure to dust and debris when not in use and becoming hot to the touch due to proximity to heating elements.
Innovation Solution
A portable laminator with a deployable feed tray, a dust cover that doubles as a feed tray, and a double-walled housing with an air gap to keep the outer cover cool and separate from heating elements, along with protrusions for upright storage and cord management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the heating elements are positioned close to the housing to achieve effective lamination, then the lamination function is improved, but the housing becomes hot to the touch creating a safety hazard
Solution Approach 1:
The housing is divided into an inner housing that contains the heating elements and an outer housing that contacts the user. This segmentation allows the heating elements to be positioned close to the lamination path for effective heating while the outer housing remains cool to the touch, resolving the contradiction between lamination effectiveness and user safety.
Solution Approach 2:
An air gap is introduced as an intermediary layer between the inner housing (containing heating elements) and the outer housing (contacting user). This air gap acts as a thermal insulator, allowing the heating elements to operate at high temperatures for effective lamination while preventing heat conduction to the outer housing, thus maintaining user safety.
2Ease of operation
If the feed slot is left open for easy access during use, then the ease of operation is improved, but dust and debris can enter and contaminate the internal mechanisms when not in use
Solution Approach 1:
The dust cover is designed to be movable, transitioning between an open position during operation for easy feed slot access and a closed position during storage to prevent dust and debris contamination. This dynamic design allows the system to adapt to different operational states, resolving the contradiction between accessibility and contamination prevention.
Solution Approach 2:
The dust cover serves multiple functions: it acts as a protective cover to prevent dust and debris contamination when closed, and it can be positioned to guide articles into the feed slot when open. This multi-functionality allows a single component to address both contamination prevention and ease of operation, resolving the technical contradiction.
3Ease of operation
If the laminator is designed for portability with a handle and upright storage capability, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The handle is integrated directly into the housing structure rather than being a separate attachment, and the protrusions for upright storage are formed as part of the housing contours. This merging of functions into the existing housing structure provides portability and storage convenience while minimizing the increase in device complexity.

AI summary
A portable laminator designed primarily for home use where the laminator includes a handle for carrying which may also act as a guide for articles being fed into the laminator. In alternate embodiments, the laminator includes a cover which may first position acts as a guide for material being fed into the laminator and in a second position acts as a cover for the laminators feed slot. In additional embodiments, the laminator includes a double walled housing to provide insulation from the heating elements.
