Foldable Cardboard Razor with Triangular Support Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional disposable razors made of plastic pose significant environmental problems due to their non-biodegradable nature, leading to environmental damage from extensive use in hotels and homestays.
Innovation Solution
A foldable razor designed using environmentally friendly materials, such as cardboard, with a unique folding mechanism that forms a three-dimensional structure for use, providing a stable grip and easy storage, and optionally incorporating a support member for enhanced strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If disposable plastic razors are used for hygiene and convenience, then guest service quality is improved, but environmental pollution worsens
Solution Approach 1:
The patent changes the material parameter from non-biodegradable plastic to biodegradable paper/cardboard, transforming the environmental impact while maintaining the disposable razor's hygiene and convenience benefits for guests
Solution Approach 2:
The patent converts the traditionally harmful plastic material into beneficial biodegradable paper material, turning what was an environmental problem into an environmentally friendly solution that maintains all functional benefits
2Volume of moving object
If a flat sheet structure is used for the razor, then storage volume is reduced, but structural strength deteriorates
Solution Approach 1:
The patent applies folding lines to transform the flat two-dimensional sheet into a three-dimensional structure during use, achieving both compact storage volume and adequate structural strength when deployed
Solution Approach 2:
The patent divides the flat sheet into multiple sections using folding lines, creating a segmented structure that provides structural support while maintaining the compact flat form for storage
3Strength
If folding lines are added to create a three-dimensional structure, then structural strength is improved, but device complexity increases
Solution Approach 1:
The patent uses simple folding lines to segment the flat sheet into functional sections, creating structural strength through straightforward geometric divisions rather than complex mechanical components
Solution Approach 2:
Instead of adding complex reinforcement structures to a flat sheet, the patent inverts the approach by using the flat sheet itself as the base and creating strength through folding, turning the apparent simplicity into structural advantage

AI summary
A foldable environmentally friendly razor includes: a flat sheet with an opening at one end and a blade at the opening. The flat sheet is provided with two main folding lines extending from one end toward the other, so that a main supporting portion is formed between the two main folding lines. Two holding portions are respectively formed between the main folding lines and both sides of the flat sheet. A first folding line joins the ends of two main folding lines. Two blade face folding lines extend respectively and diagonally towards opposing left and right sides of the flat sheet from the respective junctions of the first folding line and the main folding lines, so that the two blade face folding lines and the first folding line enclose a blade face. The two holding portions and the main supporting portion form a columnar structure to provide better support.
