Tape-Free Packaging Box Closure Using Slit-Locked Wing Parts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging solutions, such as those using packaging tape or separate holder clips, are inconvenient and contribute to plastic waste, making it difficult to reuse empty boxes and securely transport heavy-duty objects.
Innovation Solution
A packaging box design that allows assembly without tape or clips, using inward-bending bottom plates with slits and wing parts that secure inside the box, enabling easy closure and secure transport of heavy-duty items.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If packaging tape or string is used to assemble the box, then the box can be securely closed, but plastic waste increases and boxes cannot be reused
Solution Approach 1:
The box structure performs its own closing function through the interaction between bottom plates and wing parts. The bottom plates extend and bend inward to form a bottom, while the wing parts pass through slits and bend to secure the structure without requiring external packaging materials like tape or string.
Solution Approach 2:
The bottom closure structure is divided into separate functional components: bottom plates that extend from the lower end portions and wing parts that pass through slits. This segmentation allows each part to perform its specific function independently while contributing to the overall secure closure without external materials.
2Adaptability or versatility
If a portable holder clip is used to fix the bottom of the box, then the box can be reused, but the consumer must separately manufacture and purchase the clip
Solution Approach 1:
The functions of the bottom plate and the securing mechanism are merged into a single integrated structure. The bottom plates and wing parts work together as one system that both forms the bottom and secures it simultaneously, eliminating the need for separate holder clips or additional components.
Solution Approach 2:
The box structure itself provides the reusability function through its built-in bottom plate and wing part mechanism. The consumer does not need to purchase or assemble separate fixing devices because the box's own structure enables repeated use through its self-contained closure system.
3Loss of substance
If the box is designed without additional securing materials, then waste is reduced, but the security of heavy-duty objects may be compromised
Solution Approach 1:
The wing parts utilize curved bending to achieve secure locking. As the wing parts bend after passing through the slits, the curvature creates a mechanical interlock that resists outward forces, providing strong holding capacity without requiring additional securing materials.
Solution Approach 2:
The securing mechanism operates in multiple dimensions: the bottom plates extend horizontally and bend vertically to form the bottom, while the wing parts pass through slits and bend in perpendicular directions. This multi-dimensional approach creates a robust securing system that can hold heavy-duty objects without external materials.
