"a problem-solving, analysis and
forecasting tool derived from the study of patterns of invention in the global patent literature".[
Ideal final result (IFR) - the ultimate
idealistic solution of a problem when the desired result is achieved by itself.
'A contradiction is a simple clash
introducing a new solution, i.e. an improving change to one feature in a system, another feature in our system has got worse. Engineers recognize contradictions as familiar situations, such as when we improve strength by adding more material we find that this solution often makes weight get worse.
Lighter weight, same strength…….
Ride height setup tool Camshaft tensioner pressure adapter. Coolant flange
Very difficult part to fixture.
Single day lead time on printed fixture.
Materials durable enough to live in a CNC environment.
Friction hold, pneumatic release of part..
Alignment pin in center of fixture to orient coordinate system of CNC machine.
Production test fixture
Ideal for high complexity, low volume castings
Ideal for replacement parts
Reduces lead time significantly
Avoids the need to purchase expensive tooling for small sample lots
– 3D Printed molds are made with greater precision, and thus tend to hold tighter tolerances
– Allows complex internal casting geometries to be created without numerous cores
– Reduces variability in the molding process
– Reduces the labor requirements necessary for highly-complex parts
The capabilities of additive manufacturing, of which 3D printing is part, completely turn the
design process on its head from start to finish.
Hayden Osborn, a tool engineer at Boeing. Broad Adoption of Additive for Tooling. GE said that 25 percent of its products will be
impacted by additive by 2020.
Success Through Software Existing software built for subtractive processes does not enable
designers and engineers to optimize for additive processes. But new types of software coming to market, address additive processes with optimization, simulation, and build preparation for specific machine and material combinations.
Materials.. Although Additive Manufacturing has been around for more than 30 years, it’s
incorporating Additive Manufacturing into the processes, changing the face of what’s possible.
