Solution Overview
Problem
Conventional circular cutters are either complex and troublesome to use or have high production costs due to separate protection and spring components that are easily damaged.
Innovation Solution
A circular cutter design featuring a connection assembly with a flexible deformation section and elongated protection assembly that drives the cutting blade to push a rotatable disc, allowing the blade to cut objects at various angles, incorporating a fixing assembly with a locking hole and orifice system for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a protection assembly and spring are used as independent components, then the cutting blade can be protected and exposed when needed, but the production cost increases and the components are easily damaged
Solution Approach 1:
The patent combines the protection assembly and spring into a single integrated protection assembly structure. The spring is positioned within the protection assembly and works together with the flexible deformation section as unified components rather than separate independent parts, reducing the total number of components and simplifying the overall structure while maintaining the protective function.
Solution Approach 2:
The patent employs a flexible deformation section made of elastic material that can bend and deform to expose or retract the cutting blade. This flexible section replaces the need for complex mechanical linkages and multiple independent components, providing a more durable and simpler structure that maintains reliability while reducing component count.
2Ease of operation
If a conventional circular cutter design is used, then the structure is simple, but the cutting operation is troublesome and limited to specific angles
Solution Approach 1:
The patent implements a rotatable disc that can rotate to different angles, allowing the cutting blade to cut objects at various angles. The flexible deformation section dynamically changes the position of the cutting blade by deforming, enabling versatile cutting operations. This dynamic structure provides operational flexibility without requiring an overly complex mechanism.
Solution Approach 2:
The flexible deformation section automatically deforms to expose the cutting blade when the rotatable disc is rotated to a cutting position, and automatically retracts the blade when returning to the protected position. This self-service mechanism eliminates the need for additional control components or complex actuation systems, maintaining structural simplicity while achieving ease of operation.
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 design enhances usability by allowing cutting at any angle while reducing production costs and minimizing damage to components, as the flexible deformation section and elongated protection assembly work together to expose the cutting blade only when needed.
Implementation Method 1

AI summary
A circular cutter contains: a connection assembly having a first extension and a first fixing head. The first fixing head has a locking hole. The first extension has a cavity, a first groove, and a second groove. The cavity accommodates a protection assembly which has a second extension and a second fixing head, wherein the second extension has a projection and a flexible deformation section connecting with the projection, the flexible deformation section deforms, and the projection retains in the second groove of the connection assembly. An elongated section is defined between the flexible deformation section and the second fixing head and is fixed in the first groove, the second fixing head has a first orifice corresponding to the locking hole of the connection assembly, such that a fixing assembly is rotatably connected with a cutting blade and is fixed in the locking hole.
