Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ring saws with mechanical driving linkages are limited by blade thickness, as thinner blades bend or deform under mechanical forces, making them unsuitable for cutting small or intricate profiles and valuable materials.
Innovation Solution
The development of fluid-driven ring saws that utilize fluid jets to drive and support the blade without mechanical linkages, allowing for thinner blades with a thickness less than 0.02 inches, which can cut in all directions and reduce material waste.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If mechanical driving linkages are used to drive the ring saw blade, then the blade can be driven reliably, but the blade thickness must be large enough to withstand mechanical forces, causing deformation in thin blades
Solution Approach 1:
The patent replaces the mechanical driving linkage system with a fluid-driven system. Fluid jets are directed at the blade to provide driving force, eliminating the need for mechanical contact between the drive mechanism and the blade. This substitution allows thin blades to be used without deformation while maintaining reliable driving capability through fluid pressure and flow control.
Solution Approach 2:
The patent employs pneumatic or hydraulic fluid jets to drive the ring saw blade. By using compressed gas or liquid jets directed at the blade surface or through holes in the blade, the system provides sufficient driving force without mechanical contact. This approach enables the use of thin blades that would deform under mechanical linkage forces while maintaining effective cutting operation.
2Manufacturing precision
If thin blades are used to cut small and intricate profiles, then material waste is reduced and precision is improved, but conventional mechanical saws cannot drive such thin blades without deformation
Solution Approach 1:
The patent replaces mechanical driving linkages with a fluid-driven system that exerts forces on the thin blade through fluid jets rather than mechanical contact. This allows blades with thickness less than 0.02 inches to be driven without deformation, enabling precise cutting of small and intricate profiles while maintaining sufficient structural integrity through the non-contact fluid drive mechanism.
3Length of moving object
If fluid jets are used to drive the blade without mechanical linkages, then thinner blades can be used for precise cuts, but the system complexity increases
Solution Approach 1:
The patent uses pneumatic or hydraulic fluid jet systems to drive the thin ring saw blade. The system includes fluid supply lines, pressure control mechanisms, and nozzle positioning systems that direct fluid jets at the blade to provide rotational drive force. While this replaces complex mechanical linkages with fluid dynamics control, it enables the use of blades thinner than 0.02 inches without deformation, achieving superior cutting precision for intricate profiles.

Implementation Method 1
The one or more pairs of fluid nozzles are configured to deliver fluid jets that apply forces to surfaces of the plurality of holes of the ring blade to drive rotation of the ring blade
Implementation Method 2
the fluid jets delivered by the one or more pairs of fluid nozzles are further configured to support the ring blade during rotation of the ring blade such that the ring blade does not physically contact any component of the fluid-driven ring saw during rotation

AI summary
A fluid-driven ring saw includes a ring saw blade that is supported and driven by a fluid. The fluid-driven ring saw can include one or more pairs of fluid nozzles. Each pair of fluid nozzles can include a first fluid nozzle separated from a second fluid nozzle by a gap. The ring blade can be positioned within the gap. The ring blade can include a plurality of holes. The one or more pairs of fluid nozzles can deliver fluid jets that impinge upon the plurality of holes of the ring blade to drive rotation of the ring blade. The ring blade can be driven without direct contact of a mechanical linkage, such as a belt or chain. The ring blade can be relatively thinner than ring blades driven by mechanical linkages.
