Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current razor handles made of eco-friendly materials face challenges in easy separation and replacement, leading to increased waste due to difficult recycling and reuse.
Innovation Solution
A razor handle design featuring an elongated 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 like wood, metal, and glass.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If razor handles are made of eco-friendly materials, then environmental friendliness is improved, but ease of separation and replacement deteriorates
Solution Approach 1:
The razor handle is divided into separate components: a grip portion made of eco-friendly material and a body portion containing the fixing pin and latch mechanism. This segmentation allows the eco-friendly grip portion to be easily separated and replaced without compromising the overall functionality of the razor handle.
Solution Approach 2:
The fixing pin mechanism is extracted as a separate functional component from the eco-friendly grip portion. By taking out the fastening mechanism as a distinct element, the design enables easy separation of the grip portion while maintaining secure attachment during use, thus resolving the contradiction between environmental friendliness and ease of separation.
2Object-affected harmful factors
If eco-friendly materials are used in razor handles, then recyclability is improved, but device complexity increases due to separation mechanisms
Solution Approach 1:
The fixing pin is designed with asymmetric features where specific portions have different geometries (e.g., a head portion with larger diameter than the shaft portion). This local quality variation enables the pin to engage with corresponding features in the grip portion and body portion, providing secure attachment during shaving while allowing easy removal through rotational movement, thus balancing recyclability with controlled complexity.
Solution Approach 2:
Instead of designing a complex release mechanism, the invention uses a simple rotational movement of the fixing pin to achieve both secure attachment and easy separation. The pin is inserted in one direction to lock the components together, and rotated in the opposite direction to release them, inverting the traditional approach of requiring complex mechanisms for separation.
3Stability of the object's composition
If a fixed structure is used for razor handle components, then structural stability is improved, but adaptability for material replacement deteriorates
Solution Approach 1:
The fixing pin mechanism transitions from a static fixed structure to a dynamic system that can change state between locked and unlocked positions. The pin can be rotated to engage or disengage the latch portion, allowing the structure to adapt between stable operation mode and replacement mode, thus resolving the contradiction between structural stability and adaptability for material replacement.

AI summary
A razor handle is proposed. The razor handle may include an elongated-type grip portion having a hollow portion, and a body portion comprising a latch portion. At least part of the body portion may be configured to be accommodated in the hollow portion. The razor handle may also include a head portion configured to be connected to a razor cartridge, the head portion connected to one side of the body portion. The razor handle may also include a fixing pin configured to be coupled to the other side of the body portion. When the fixing pin is positioned on the other side of the body portion, the fixing pin may be configured to be latch-coupled with the latch portion by rotating in a first direction around a rotational axis passing through the body portion and parallel to a longitudinal direction of the body portion.
