Paper Post Packaging for Secure Adapter Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing product packaging often uses plastics for structural robustness and durability, which are not environmentally friendly and may not provide an intuitive user experience, while eco-friendly materials struggle to balance security, aesthetics, and ease of access.
Innovation Solution
The packaging uses paper posts with a base panel and side walls that taper towards each other, forming an interference fit with products, and is assembled from recyclable materials, allowing secure attachment and repeated use without damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If plastics are used for posts to secure products, then structural robustness and durability are improved, but environmental friendliness deteriorates
Solution Approach 1:
The patent changes the material parameter from plastic to paper, and modifies the geometric parameters of the post (tapering shape with undercut) to achieve sufficient strength and secure attachment while using an environmentally friendly material. The paper post maintains structural integrity through its specific geometry rather than relying solely on material properties.
Solution Approach 2:
The solution uses paper as the primary material for the post, combining it with the packaging structure (cover and base panel) to create a composite securing mechanism. The paper post works in conjunction with the packaging components to achieve both environmental friendliness and functional robustness.
2Object-affected harmful factors
If eco-friendly materials are used for packaging, then environmental friendliness is improved, but structural robustness deteriorates
Solution Approach 1:
The patent modifies the geometric parameters of the paper post, including tapering the sides and creating an undercut shape, to compensate for the lower inherent strength of paper material. These parameter changes enable the paper post to provide sufficient structural support and secure product attachment.
Solution Approach 2:
The paper post features localized structural enhancements such as the undercut region and varying thickness (tapered sides) that concentrate strength where needed for product attachment, while the overall structure remains environmentally friendly. The local geometric features provide the necessary mechanical properties.
3Object-affected harmful factors
If paper posts are used instead of plastics, then environmental friendliness is improved, but ease of manufacture deteriorates
Solution Approach 1:
The paper post is designed as a separate component that can be individually manufactured and then assembled into the packaging structure. This segmentation allows for specialized manufacturing processes optimized for paper forming, such as die-cutting and folding, while maintaining ease of assembly into the final product.
Solution Approach 2:
The specific geometric parameters of the paper post (tapered sides, undercut shape) are optimized for manufacturing efficiency. These parameters allow the post to be formed from a single piece of paper through cutting and folding operations, simplifying the manufacturing process despite the material change from plastic.
4Reliability
If paper posts with tapered sides are used, then secure attachment is improved, but device complexity increases
Solution Approach 1:
The paper post combines multiple functional features into a single integrated component. The tapered sides and undercut shape are incorporated into one piece that performs both structural support and secure product attachment functions, reducing overall device complexity while maintaining reliable attachment.
Solution Approach 2:
The geometric parameters of the paper post (tapering angle, undercut depth) are optimized to achieve secure attachment through the interference fit mechanism. The parameter optimization ensures reliable product securing while maintaining a simple, elegant design without excessive complexity.

Function Achieved in This Case
The solution provides a secure, reusable, and aesthetically pleasing packaging that minimizes environmental impact by using recyclable materials while ensuring easy product access and robust protection.
Implementation Method 1
The side walls taper toward each other in a direction parallel to the base panel and in a direction perpendicular toward the base panel. The two side walls each form an undercut between the base panel and the top panel.

AI summary
Packaging with paper posts for securing accessories such as electronic adapters to packaging. Such packaging includes a base panel and a paper post. The paper extends from the base panel and includes two side walls and a top panel. The side walls couple to and extend away from the base panel. The top panel extends between and is joined to the two side walls along fold lines. The top panel is spaced away from the base panel by the side walls. The two side walls taper toward each other in a direction parallel to the base panel and in a direction perpendicular toward the base panel.
