Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current dental floss packaging is costly and environmentally impactful due to complex assembly requirements and additional packaging, leading to increased manufacturing and disposal issues.
Innovation Solution
A single-piece, molded dental floss package with a box-shaped body, a closing body, and a detachable additional body for display, featuring a thin folding line and interference coupling to eliminate the need for adhesives and reduce assembly complexity, while providing a dust-proof housing and easy floss access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional multi-component packaging with adhesives is used, then secure enclosure is achieved, but manufacturing complexity and cost increase
Solution Approach 1:
The patent merges multiple separate packaging components (box body, closing body, additional body) into a single integrated molded structure. The box-shaped body, closing body, and additional body are all obtained integrally from a single piece of transparent plastic material, eliminating the need for separate manufacturing and assembly operations while maintaining the secure enclosure function through built-in interference coupling features.
Solution Approach 2:
The single-piece molded structure serves multiple functions simultaneously: it provides the box-shaped housing, the closing mechanism, the additional display body, and the interference coupling features all in one component. This multi-functional design eliminates the need for separate adhesive joining operations while achieving secure assembly.
2Strength
If multiple materials (plastic and cardboard) coupled with adhesives are used, then structural integrity is achieved, but environmental impact increases
Solution Approach 1:
The patent uses a homogeneous material approach by constructing the entire package from a single type of transparent plastic material. This eliminates the need for adhesive bonding between different materials (plastic and cardboard) and creates a uniform structure that is easier to recycle, thereby reducing environmental impact while maintaining structural integrity through interference coupling.
Solution Approach 2:
The single-piece molded package is designed as a disposable unit that combines structural integrity with ease of disposal. By using a single material system without adhesives or mixed materials, the package maintains its strength during use but becomes significantly easier to recycle or dispose of, reducing environmental harm.
3Adaptability or versatility
If separate components requiring assembly are used, then functional requirements are met, but assembly time and labor increase
Solution Approach 1:
The patent combines multiple functional components into a single molded structure that is produced as one piece. The box-shaped body, closing body, and additional body with their respective functions (housing, sealing, display) are all integrated into one component, eliminating assembly operations and reducing production time while maintaining all necessary functions.
Solution Approach 2:
The package is pre-formed as a complete single-piece structure during molding, with all functional features (walls, openings, coupling interfaces) already in place. This preliminary formation eliminates the need for subsequent assembly operations, significantly reducing assembly time and labor requirements.
4Reliability
If traditional packaging with additional blister pack is used, then product protection is achieved, but packaging cost and waste increase
Solution Approach 1:
The patent merges the product packaging with the display function into a single integrated structure. The box-shaped body provides product protection while the additional body with aperture enables display, eliminating the need for separate blister packaging and reducing packaging material waste.
Solution Approach 2:
The single-piece molded package simultaneously provides product protection, sealing, and display functions. The transparent material and integrated additional body with aperture allow the package to serve as both protective housing and display unit, eliminating the need for additional blister packs and reducing overall packaging waste.
