Paper Hook Display Card Strength and Recyclability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hook-shaped display cards for small accessories are made of mixed materials, including paper and film, which are not recyclable and thus not environmentally friendly.
Innovation Solution
A fully paper-made hook-shaped display card is designed, comprising cardboard on the front and plastic-free paper on the bottom, with V-grooves cut into the paper to form a strong hook when folded.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a hook-shaped display card is made entirely of cardboard, then it is simple and easy to manufacture, but the hook lacks sufficient strength and may break or fail to hook onto display racks
Solution Approach 1:
The display card combines cardboard and plastic-free paper to create a composite structure. The cardboard provides rigidity and structural support, while the plastic-free paper adds tensile strength and flexibility. This composite material approach resolves the contradiction by achieving sufficient hook strength without compromising ease of manufacture, as both materials are processed using standard paper manufacturing techniques.
Solution Approach 2:
Different regions of the display card use different materials optimized for their specific functions. The front portion uses cardboard for structural integrity and display surface, while the bottom portion uses plastic-free paper for the hook formation area, providing the necessary flexibility and strength. This local differentiation resolves the strength issue while maintaining overall manufacturing simplicity.
2Strength
If a film is glued to the bottom of the display card using hot pressing, then the hook has sufficient strength, but the display card becomes non-recyclable and environmentally harmful
Solution Approach 1:
The invention extracts and removes the plastic film component from the traditional display card structure. By eliminating the film entirely and using only plastic-free paper for the bottom layer, the design maintains sufficient strength through the paper's inherent properties and the composite structure, while completely resolving the environmental harm and recyclability issues associated with plastic films.
Solution Approach 2:
The invention changes the material parameter of the bottom layer from plastic film to plastic-free paper. This parameter change maintains the functional requirements for hook strength and durability while fundamentally altering the environmental profile from non-recyclable to fully recyclable, thus resolving the contradiction between strength and environmental harm.
3Device complexity
If cardboard is used to form the hook, then the display card is simple in structure, but the perforation marks lack durability and may break during jewelry attachment
Solution Approach 1:
The composite structure of cardboard and plastic-free paper provides enhanced durability for the perforation marks. The plastic-free paper layer reinforces the areas where perforations are made, preventing breakage during jewelry attachment while maintaining the overall simplicity of the single-layer folded structure. This resolves the contradiction between structural simplicity and perforation durability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution allows for a recyclable and environmentally friendly display card that addresses the issue of insufficient strength in cardboard hooks, preventing breakage and enhancing the durability of perforation marks for attaching jewelry.
Implementation Method 1
two V-grooves are opened near a top edge of the plastic-free paper, and a hook for hanging on a display rack is formed by the display card as a whole bent along the two V-grooves towards one side of the plastic-free paper in two folds
Implementation Method 2
adhesive is applied along the V-grooves
