Folding Knife Adjustable Blade Unfolding Angle Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional folding knives have a fixed blade unfolding angle, limiting their application scenarios and user-defined adjustments, which restricts their functionality and playability in various usage situations.
Innovation Solution
A folding knife with an adjustable blade unfolding angle is designed, featuring an angle adjustment block between the blade and the handle, allowing the blade to be hinged to the block and the unfolding angle to be adjusted by changing the angle of the block relative to the handle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the blade unfolding angle is fixed during manufacturing, then the structure is simple and stable, but the adaptability to different usage scenarios is limited
Solution Approach 1:
The patent applies the dynamics principle by transforming the fixed blade angle into an adjustable one. The blade can now be set to different unfolding angles (such as 180 degrees or smaller angles like 90 degrees) and locked in position, allowing the knife to adapt to various usage scenarios including straight cuts and bent/sickle-shaped cuts, thereby resolving the contradiction between structural simplicity and adaptability.
2Adaptability or versatility
If an angle adjustment block is added to enable blade angle adjustment, then the adaptability and functionality are enhanced, but the device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the knife structure into distinct modular components: the handle, the blade, and the angle adjustment block. This modular design allows each component to perform its specific function independently while being easily assembled and disassembled, enhancing functionality without excessively increasing overall complexity.
Solution Approach 2:
The angle adjustment block serves as an intermediary component between the handle and the blade. It mediates the connection and enables angle adjustment functionality, allowing the blade to be positioned at different angles relative to the handle while maintaining structural integrity and ease of operation.
3Ease of operation
If the blade is hinged to the knife handle with a fixed connection, then the manufacturing precision is easier to achieve, but the ease of operation for angle adjustment is reduced
Solution Approach 1:
The patent applies preliminary action by pre-setting multiple predetermined angle positions (such as 180 degrees, 90 degrees, and other intermediate angles) on the angle adjustment block. These positions are pre-marked or pre-structured to guide users in achieving accurate blade angles without requiring complex measurement or adjustment procedures during operation, thus maintaining manufacturing precision while improving ease of operation.

AI summary
The present disclosure provides a folding knife with an adjustable blade unfolding angle and an adjusting method for a blade unfolding angle of a folding knife. The folding knife with an adjustable blade unfolding angle includes a knife edge and a knife handle. The folding knife in the present disclosure has a simple and reasonable structure, and a blade unfolding angle can be adjusted by adjusting angles of angle adjustment blocks. When a “sickle” needs to be used in a specific scene, the angle adjustment blocks are rotated towards an inner side of the knife handle by a certain angle to obtain a smaller unfolding angle of the knife edge than a normal angle. The needs for using the knife in specific occasions are met, the functionality and playability of the folding knife are improved, and the angle adjustment is simple.
