Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for producing cutting tools, such as saw blades and bands, face limitations in material choice and process efficiency due to the requirement for cutting edge materials to be in wire form and the need for high-temperature welding processes, which restricts the selection of materials and increases production costs.
Innovation Solution
A method involving the welding of particulate cutting material between two flat carriers, allowing for continuous production of bimetallic strips with a stable connection, enabling the use of a wide variety of materials and reducing production costs by eliminating wire production costs and simplifying the process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wire form cutting material is used and welded to flat carriers, then a stable connection is achieved, but material selection is limited and production costs increase
Solution Approach 1:
The patent changes the physical form parameter of cutting material from wire to powder, enabling a wider range of materials to be used while maintaining connection stability through the welding process. This parameter change resolves the contradiction by allowing material versatility without sacrificing connection reliability.
Solution Approach 2:
The patent creates a composite structure where cutting material powder is welded between flat carriers, forming a new composite material system. This composite approach enables the use of diverse cutting materials that would not be available in wire form, while the welding process ensures stable connection between the components.
2Reliability
If wire form cutting material is used, then connection stability is achieved, but production costs increase due to wire production requirements
Solution Approach 1:
The patent replaces expensive wire form cutting material with cheaper powder form cutting material. The powder can be more readily produced and is less costly than wire, while still achieving the desired connection stability through the welding process between flat carriers.
Solution Approach 2:
By changing the form parameter from wire to powder, the patent eliminates the need for wire production processes, thereby reducing manufacturing costs while maintaining connection stability through the welding of powder material between carriers.
3Reliability
If high-temperature welding processes are used, then stable connection is achieved, but material selection is restricted and process complexity increases
Solution Approach 1:
The patent changes the form of cutting material to powder, which can be more easily and efficiently welded using simpler processes compared to wire form. This parameter change reduces process complexity while maintaining connection stability and expanding material selection flexibility.
4Strength
If conventional bimetallic strips with welded edge wire are used, then toughness and flexural strength are achieved, but significant material loss occurs during tooth profile machining
Solution Approach 1:
The patent performs preliminary action by forming the cutting material in the desired configuration before final tooth profile machining. The powder form cutting material is welded between flat carriers in a way that pre-establishes the material distribution, reducing the need for material removal during subsequent machining operations.
