Razor Handle With Rotating Fixing Pin for Component Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wet razors made primarily of plastic materials pose environmental challenges due to their disposal issues, as components made of eco-friendly materials are difficult to separate and replace, hindering recycling and reuse.
Innovation Solution
A razor handle design featuring a grip portion with a hollow portion, a body portion with a latch portion and fixing pin mechanism that allows for easy separation and replacement by rotating the fixing pin around a rotational axis, facilitating the use of eco-friendly materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If eco-friendly materials are used to manufacture razor components, then environmental friendliness is improved, but separability and replaceability of components deteriorate
Solution Approach 1:
The razor handle is divided into separable components: a grip portion made of eco-friendly material and a body portion containing the fixing mechanism. The fixing pin and latch portion enable the grip portion to be detached from the body portion, allowing the eco-friendly component to be separated for proper disposal or recycling while maintaining ease of separation through the mechanical coupling mechanism.
2Ease of manufacture
If traditional plastic materials are used for razor handle, then ease of manufacture and component integration are improved, but environmental compatibility deteriorates
Solution Approach 1:
The razor handle is segmented into a grip portion (eco-friendly material) and a body portion (containing mechanical components). This segmentation allows the use of environmentally friendly materials for the grip portion while maintaining traditional materials for the functional body portion, thus improving environmental compatibility without compromising manufacturing ease.
Solution Approach 2:
The razor handle employs a composite structure combining eco-friendly materials (such as wood, bamboo, or biodegradable polymers) for the grip portion with traditional materials for the body portion. This composite approach allows each component to be optimized for its specific function while addressing environmental concerns.
3Ease of manufacture
If disposable razor design is used, then ease of manufacture and initial cost are improved, but waste generation and recyclability deteriorate
Solution Approach 1:
The razor is designed with separable components where the grip portion can be detached from the body portion. This segmentation enables the reusable body portion to be retained while the grip portion can be replaced or disposed of, reducing overall waste generation compared to completely disposable razors.
Solution Approach 2:
The design allows the body portion containing the fixing mechanism to be recovered and reused, while only the grip portion needs to be discarded or replaced. This selective discarding and recovering approach reduces waste generation and improves recyclability compared to disposable razor designs.
