Single-Piece Display Box with Tear-Line Conversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display boxes, either 'twin pack' or single piece designs, face issues with material duplication, resistance when stacked, and aesthetically undesirable tear lines, which compromise the finish and functionality of the display window.
Innovation Solution
A single-piece display box made from a cut and stamped sheet with creased and tearable folding lines, featuring a double front that can be removed via a lateral tear line, minimizing perforations and cuts, and ensuring a perfectly finished display window without visible tears, enhancing stacking resistance and reducing material duplication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If twin pack display boxes are used, then the box can be separated into lower and upper parts for display, but the manufacturing process becomes complex and execution time increases
Solution Approach 1:
The single sheet is segmented into functional zones (base section, lateral sections, front part, back part) with predetermined fold lines and tear lines that allow the box to be converted into a display case by separating specific portions along these lines, achieving display adaptability without complex manufacturing
Solution Approach 2:
The sheet is pre-configured with fold lines, creases, and tear lines during manufacturing, so that at the distribution point, conversion to display mode simply requires pulling along the predetermined tear lines, eliminating complex assembly steps and reducing execution time
2Adaptability or versatility
If twin pack display boxes are used, then the box can be separated for display, but stacking resistance is weakened due to cuts and perforations
Solution Approach 1:
The design uses strategic fold lines and minimal tear lines positioned only where separation is needed for display conversion, preserving the integrity of the main structural walls and maintaining stacking resistance while enabling display adaptability
Solution Approach 2:
The sheet structure has different properties in different zones: the lateral and back sections maintain full structural integrity for stacking, while the front part and flaps are designed with tear lines for display conversion, optimizing both strength and adaptability locally
3Loss of substance
If single piece display boxes are used, then material duplication is reduced, but the display window edge becomes badly finished due to tearing
Solution Approach 1:
The display window edge is pre-cut with a finished appearance during sheet manufacturing, and the tear lines are strategically positioned away from the window edge, so that when the box is converted to display mode, the window maintains its factory-finished appearance without tear damage
Solution Approach 2:
The double front part containing the tear lines is designed to be completely removed from the box, extracting the tearing action away from the display window area, allowing the window edge to remain intact and aesthetically finished
4Loss of substance
If single piece display boxes are used, then material duplication is reduced, but tear lines diminish resistance and are aesthetically undesirable
Solution Approach 1:
The sheet is divided into sections connected by fold lines rather than requiring multiple separate pieces, eliminating material duplication while confining tear lines to non-structural areas (front part and flaps) where they do not compromise overall structural resistance
Solution Approach 2:
The structural walls (lateral and back sections) are designed without tear lines to maintain strength and resistance, while the front part and flaps are designed with tear lines for easy removal, achieving material efficiency without sacrificing structural integrity

AI summary
Display box assembly in one piece based on a single sheet which is provided with two large lateral sections, joined by a section which, when the box is assembled, adopts a back position and emerging from the ends of the large lateral front sections one of which is joined by means of a tear line so that it may be removed, and another which has a window which is pre-cut in the factory with finished edges, where it joins the double front, which is fitted in a groove made for this purpose on the double front, with the closing tab being at a lower height than the double front, as this is arranged on its inside face. Due to its configuration, material is not duplicated, the display window is provided with finished edges, and a box is obtained which is easier to stack, and which is made from one piece and its assembly may be mechanised, without the need for any special machinery.
