• Presentation by David Verduyn, C2C Solutions, at the November, 2006 PDMA Meeting, Detroit Chapter, held at UDM; The trimming rules and the ideas for many of the examples were drawn from this presentation
• Various trimming rules also appear in the Triz literature• Others as noted within

The Trimming Technique
• Most engineers tend to focus their innovative thoughts on more, more, more
• Sometimes there’s an easier way to innovate• The Trimming Technique involves systematically
exploring the various components/functions/systems in a product and looks for ways to trim some to generate new ideas
• The six rules on the following slide provide some direction when considering what might be trimmed

Trimming Rules
• Rule 1: The function does not need to exist• Rule 2: The function can be performed by another
component or an element in the larger system• Rule 3: The recipient of the function can perform the
function itself• Rule 4: The recipient of the function can be eliminated• Rule 5: The function can be performed better by a
new/improved part providing enhanced performance or other benefits
• Rule 6: A new or niche market can be identified for the trimmed product

When to use Trimming
• We have a commodity product and need to differentiate it or create a new market
• Our product or process is too complex and/or too costly• Our competitor has a patent we need to circumvent
17
How to use Trimming
• Decompose existing product and diagram it by components and by functions
• Systematically consider each component and each function in the context of the six trimming rules to look for opportunities
