Bookmark Card Display Case for Waste Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The presentation of gift items generates significant waste due to the use of single-use containers, boxes, bags, and glues, contributing to environmental pollution, and there is a need for reusable containers that can be assembled without adhesives.
Innovation Solution
A bookmark card and display case made of thick cardboard, punched into sections with creases, allowing for assembly into a display case without glues, which can be converted back into a bookmark card, providing a dual-use item that reduces waste.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If single-use containers, boxes, bags, and glues are used for gift presentation, then the presentation function is achieved, but significant waste and environmental pollution are generated
Solution Approach 1:
The packaging card serves multiple functions: it acts as both the presentation container for the gift article and a reusable bookmark. The card includes a bookmark portion with a tear-off section that can be detached to leave the article secured in the display case, while the remaining card functions as a bookmark. This multi-functionality eliminates the need for separate packaging and bookmark items, reducing waste without compromising presentation capability.
2Ease of operation
If reusable containers are designed to be assembled without glues or additional components, then assembly is simplified and waste is reduced, but the structural strength and stability may be compromised
Solution Approach 1:
The packaging card is divided into distinct functional sections: a display case portion, a bookmark portion, and a tear-off section. These segments are connected through precise die-cut lines that allow clean separation. The segmentation enables easy assembly by simply folding along crease lines without requiring adhesives, while each segment maintains its structural integrity through the thick cardboard material and clever geometric design of the interlocking features.
Solution Approach 2:
The packaging structure incorporates self-securing features where the article is held in place through the interaction of die-cut edges and friction fits within the display case cavity. The bookmark portion automatically secures the article when folded into position, eliminating the need for external fasteners, glues, or additional components. This self-service mechanism maintains reliability while simplifying assembly.
3Strength
If thick cardboard is used to provide rigidity to the display case, then structural strength is improved, but the material consumption and potential waste increase
Solution Approach 1:
The packaging card utilizes local quality by varying the thickness and density of cardboard only where structurally necessary. The display case portion uses thicker, more rigid cardboard to provide the necessary support for holding the article, while the bookmark portion uses thinner material since it requires less structural strength. This localized differentiation maintains overall rigidity while minimizing total material consumption and potential waste.

AI summary
The invention set forth herein is a bookmark card configured into several sections by creases and two openings. Once the lower sections are folded and the openings are aligned, the latter are connected by inserting the article to be presented, thus forming its dual-use upright configuration for display of small gifts and/or promotional items and its collapsed or unfolded configuration as a bookmark. The end consumer obtains two articles in one: a presentation support and a bookmark card, without having to use glue to assemble it in the upright configuration and avoiding the production of unnecessary waste after presentation of small articles.
