Tonka Effect

A phenomenon in engineering and manufacturing where a product is built with such extreme durability and high-quality standards that it becomes financially "too good" for the manufacturer. Because the product refuses to break, wear out, or fail (much like the original steel Tonka trucks), the consumer has no reason to buy a newer model for decades. This "over-engineering" inadvertently kills the company's future sales and replacement market, often forcing brands to pivot toward planned obsolescence just to stay in business.

"The HP EliteBook 840 G1, the early Samsung Galaxy S series (like the S2 or S4), and the diesel Toyota Corolla are classic victims of the Tonka Effect: they were so indestructible and reliable that people are still using them 15 years later instead of buying the fragile, unrepairable models of 2026."
