Operator: "Abandon Symmetry" Recommendation: If an object is symmetrical, consider reducing its weight by abandoning the symmetry. Consider, for example, excluding a part of the object that does not bear the main load. Illustration: Designing asymmetrical mounts For aesthetic reasons, motor and generator mounts are often designed with symmetrical shapes. But because the machines rotate, the load on the mounts is actually asymmetrical. To reduce the weight and conserve material, mounts for non-reversible units should be designed to support only the loads they must actually bear. Ideas Generated: Vary the thickness of the ring, reducing the thickness where permissible. From Thinking to Inventing 38 / 41
Operator: "Strengthen Individual Parts" Recommendation: Consider strengthening those parts that bear the main load, and also reducing the weight of the parts that do not bear the main load. Illustration: Pump housing made of standard pipe The housing of a high pressure pump, made from a steel casting, was complicated in shape. Since cavities and uneven surfaces were frequently found in the casting (necessitating repairs made by welding), a very thick, heavy casting was used. The defects were eliminated, and the weight reduced by nearly half, when the housing was fabricated by welding several pieces together. High-strength rolled pipe was used for the section that was required to withstand the greatest pressure. Ideas Generated: Make a multi-layer ring Add "ribs" to a thin ring From Thinking to Inventing 39 / 41
4 : Concept #1: Make the ring thin, but composed of several circular ribs. These ribs can significantly increase the strength of the ring with a less significant increase in mass. From Thinking to Inventing 40 / 41
Concept #2: Make a multi-layer ring as described by the following: Internal layer made of a thin steel ring Intermediate layer to absorb the energy of the fragments, made of: radial brush balls honeycomb External layer to hold the fragments, made of: steel pipe coil textile or wire needles From Thinking to Inventing 41 / 41
