Tamper-Evident Box Tabs and Wire-Tie Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing boxes lack effective tamper-evident mechanisms that do not require lifting the cover, compromising security and functionality when such mechanisms are not needed.
Innovation Solution
A box design featuring first and second tabs with through-holes on the cover and lower container, allowing tamper-evident means to be installed without lifting the cover, using wire-ties that must be broken to open the box, providing evidence of opening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If tamper-evident means are installed by threading through tabs on the cover and lower container, then tamper-evident functionality is achieved, but the box structure becomes more complex
Solution Approach 1:
The tamper-evident mechanism is segmented into separate components: tabs protruding from the cover, corresponding tabs on the lower container, and tamper-evident means (such as wire ties or ribbons) that pass through these tabs. This segmentation allows the tamper-evident functionality to be added as a separate assembly that can be installed without altering the basic box structure.
Solution Approach 2:
The tabs are pre-formed as integral parts of the cover and lower container during the box manufacturing process. The tamper-evident means are prepared separately and can be installed later by simply threading them through the pre-positioned tabs, eliminating the need for complex assembly operations.
2Ease of operation
If tamper-evident means are installed without lifting the cover, then installation ease is improved, but the tabs must be accessible from the closed box state
Solution Approach 1:
The tabs are configured to protrude from the closed box state, making them accessible from the outside without requiring the cover to be lifted. This dimensional arrangement allows the tamper-evident means to be installed through tabs that are visible and accessible when the box is in its normal closed position.
Solution Approach 2:
The tabs serve as intermediary elements that bridge the cover and lower container, providing accessible access points for installing tamper-evident means. These tabs act as mediators that enable the installation process without requiring direct access to the interior of the box.
3Adaptability or versatility
If tamper-evident means are made optional, then box versatility is improved, but the installation process becomes more complex
Solution Approach 1:
The tamper-evident means are designed to be optional and removable, allowing the box to dynamically adapt between different functional states: with tamper-evident functionality activated or deactivated. This dynamic configuration enables the same box structure to serve different purposes based on user needs.
Solution Approach 2:
The tamper-evident means are extracted as a separate, optional component from the basic box structure. The tabs remain as permanent features of the box, while the tamper-evident means can be added or removed as needed, allowing for flexible functionality without complicating the basic box manufacturing process.

AI summary
A box has a lower container and a cover. The lower container has a rectangular bottom wall, two first side walls opposite to each other and two second side walls opposite to each other. The cover has a rectangular main wall opposite to the bottom wall, two third side walls opposite to each other and two fourth side walls opposite to each other. The third side walls are adjacent and outside an upper portion of the first side walls, respectively. The fourth side walls are adjacent and outside an upper portion of the second side walls, respectively. A respective first tab with a through-hole protrudes downwards from a lower edge of both third side walls. A respective second tab with a through-hole is cut in both first side walls and has a side attached to the respective first side wall. Tamper evident means pass through respective couples of first and second tabs of adjacent third and first walls.
