Display Box Front Wall with Removable Panel for Aesthetic Opening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display boxes with removable portions have an unappealing appearance due to visible pre-notch lines when opened, and their manufacturing requires specialized equipment or excess wrapping material.
Innovation Solution
A display box design featuring a front wall with a U-shaped panel and an internal panel that closes the opening, made from a single blank with strategically placed pre-notch lines and folding elements, allowing for a neat and cost-effective construction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a removable portion is detached along pre-notch lines to open the display box, then the product can be extracted, but the pre-notch line becomes visible and creates an unpleasant appearance
Solution Approach 1:
The front wall is divided into a first shaped panel and a second panel that are completely detached from each other. The second panel can be removed independently to extract the product, while the first shaped panel remains intact and maintains the aesthetic appearance of the display box front wall.
Solution Approach 2:
The second panel is extracted as a separate removable component from the front wall assembly. This allows the opening function to be performed by removing only the necessary panel without exposing the pre-notch lines that would otherwise be visible on the main front wall structure.
2Ease of operation
If two separate blanks are used to manufacture the display box with the second panel, then the opening mechanism works properly, but a special cartoning machine is required increasing device complexity
Solution Approach 1:
The first shaped panel and the second panel are merged into a single blank with strategically placed pre-notch lines. The pre-notch lines allow the second panel to be completely detached from the first shaped panel during the cartoning process, enabling the opening mechanism to function while using standard manufacturing equipment.
Solution Approach 2:
Pre-notch lines are预先 positioned in the blank during manufacturing to facilitate the complete detachment of the second panel. These pre-notch lines are strategically placed so that when the second panel is removed, the pre-notch lines do not become visible on the front wall, thus maintaining appearance while enabling easy panel separation with standard equipment.
3Ease of manufacture
If a single blank with an additional panel is used, then manufacturing is simplified, but the amount of wrapping material increases
Solution Approach 1:
The single blank is designed with localized pre-notch lines only where needed to detach the second panel, rather than adding material throughout. The pre-notch lines are strategically positioned to enable panel separation without requiring excess wrapping material, thus maintaining manufacturing simplicity while minimizing material waste.
4Ease of manufacture
If the second panel is made from a single blank connected to the top wall, then manufacturing is simplified, but the amount of wrapping material increases
Solution Approach 1:
The connection between the second panel and top wall in the single blank design is achieved through localized pre-notch lines at specific connection points. This allows the second panel to be completely detached when needed while using minimal wrapping material, as the pre-notch lines are only placed where structural connection is required rather than using excess material throughout the entire panel assembly.

AI summary
A display box has a front wall (4), a back wall (5), a top wall (2), a bottom wall (3), and two side walls (6, 7); at least the front wall (4) being defined by a first shaped panel (8) defining, in turn, an opening (9) for extracting a product from the display box, and a second panel (11), at least partially removable which is adapted to close the opening (9) and is hinged on an upper edge (10) of the first panel (8).
