New Product Development Case Study: Old vs New Insulator Shims
Old Insulator Shims
The old insulator shims, typically made from solid plastic or plywood, lacked flexibility and required custom ordering to match exact height specifications—leading to longer lead times, higher material waste, and limited adaptability in the field

New Insulator Shims
In contrast, the newly designed insulator kits feature a negative space design that uses significantly less material and is available in multiple thickness options. This allows for on-site configuration to achieve the precise thickness needed, improving efficiency, reducing cost, and simplifying installation.
