Technology Development - Concept

Technology Development - Concept

Development of Technology which can be used to design a series of Products or Processes in a short period of time by developing the Robust Product Function before the completion of Product Design.

Technology Development - Concept

Technology Development is useful for a family of products rather than a particular product. To understand this, consider an automotive braking system. If a manufacturer makes 3 models of cars, should the braking system optimization be conducted 3 times? Although this is often the case, Technology Development suggests that the braking system be optimized as a technology. Once that is done, the braking system can be adapted to other model or sizes.

Technology Development is an extension of Robust Design where laboratory conclusions which can be reproduced in the factory with higher noise level in the manufacturing process.

Robust Design is based on the 2-Step process. Technology Development is one level higher although it still involves the 2-step process. The can be understood if one thinks of Robust Design as optimizing points (of order zero) while Technology Development optimizes straight lines (of order one). Indeed future techniques could be developed to optimize curves (of order 2 or higher).

Adjust sensitivity

Technology Development must be started simultaneously with product planning. Once such technology is developed a new product design can be completed by tuning. The redundancy of individual products or process development can be avoided.

The figure below shows New Product: Traditional Development where the entire optimization process (Product Design, Tolerance Design, and Tuning) is repeated for every new product. This is not a good method because Tolerance Design and Tuning, both of which increases costs, are done at an early R&D stage.

The figure below shows New Product: Technology Development where the full optimization process is done only once (or as necessary). R&D in Technology Development approach to New Product Development is based on Robust Design and Technology Development. This is a good method because in the

  1. R&D stage
    1. Technology Development is focused
    2. Parameter Design is exhausted
    3. Tuning research is done (but NO tuning is done)
  2. Manufacturing stage
    1. Tolerance Design is done in this stage
    2. Tuning is done in this stage

For new products, only Tolerance Design and Tuning need to be done. Thus, Technology Development can be used to optimize a family of products.
