Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power adapter packaging for electronic cigarettes often relies on glue, adhesives, and tape, which can be inconvenient and not environmentally friendly.
Innovation Solution
A self-locking display box design using a blank with foldable panels and tabs that snap into place, minimizing the use of adhesives and promoting recyclability, suitable for housing power adapters for electronic cigarettes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If glue, adhesives, and tape are used to assemble the packaging box, then the structural strength and stability are improved, but the environmental friendliness and recyclability deteriorate
Solution Approach 1:
The packaging box is divided into separate modular components (base panel, side panels, top panel) that can be assembled and disassembled without permanent bonding. Each panel is designed with interlocking features that allow structural integrity during use while enabling complete separation for recycling.
Solution Approach 2:
Chemical bonding methods (glue, adhesives, tape) are replaced with a mechanical interlocking system. The tab-and-slot mechanism provides structural strength through physical engagement rather than chemical bonding, allowing the box to maintain integrity while being fully recyclable.
2Object-affected harmful factors
If tabs and notches are used for self-locking assembly, then the use of adhesives is minimized and recyclability is improved, but the assembly complexity increases
Solution Approach 1:
The packaging box performs its own assembly function through self-locking tabs and notches that automatically engage when panels are folded into place. The design requires no external tools, adhesives, or complex fastening mechanisms - the structure assembles itself through its geometric features.
Solution Approach 2:
Rather than making the entire structure complex, the patent applies simple tab-and-notch features only at specific critical locations where panels need to connect. The majority of the panel surfaces remain simple and flat, minimizing overall complexity while providing sufficient interlocking capability.
3Ease of manufacture
If a self-locking display box design is used, then the manufacturing simplicity and recyclability are improved, but the structural stability may deteriorate
Solution Approach 1:
Multiple structural functions are merged into single integrated features. The tabs serve both as structural connectors and as positioning guides, while the notches provide both alignment and locking functions. This consolidation maintains structural stability while simplifying manufacturing by reducing the number of separate components and assembly steps.
Solution Approach 2:
The packaging utilizes composite construction combining rigid panel materials with integrated paperboard tabs and notches. This composite approach allows the main panels to provide structural strength while the paperboard interlocking features provide assembly simplicity and recyclability.

AI summary
A self-locking display box is disclosed, which is configured to receive one or more electrical components, wherein the box is erected from a blank having a deck panel having a pair of tabs, which are configured to fit within a corresponding notch of a back panel and which snaps into place to form a rectangular box. The back panel has an upper flap panel and a lower flap panel, the upper flap panel and the lower flap panel each having the corresponding notch therein. The deck panel has a pair of tabs, which extend outward from an upper edge and a lower edge of the deck panel, respectively, and are configured to be received within the corresponding notches of the upper flap panel and the lower flap panel upon assembly of the box.
