Rethink the design
The existing components were not considered in isolation. Their functions within the complete metering system were what mattered.

Fewer components.
A better system.
Precision comes from interaction. How KTH Yildiz redesigned a metering system for gas cartridges used in nailers, targeting consistent gas delivery, repeatable driving performance and a predictable number of shots.
The starting point
One cartridge.
Inconsistent results.
The original ADK system consisted of 13 components. Gas metering was not sufficiently consistent: driving performance and the number of usable shots per cartridge varied.
In adverse cases, excessive dosing caused the nailer to malfunction, commonly described as flooding. The task therefore went beyond improving a single plastic component.
Our development approach
Not just each part.
The complete interaction.
Ali Yildiz questioned the existing design and reworked its components so the system could operate with fewer parts.
Reduce the component count
Redesign made it possible to reduce the number of individual parts. The function of the complete system remained the benchmark.
Coordinate parts precisely
The remaining components were manufactured in coordination with one another to fulfil their metering function repeatably.
The result in use
Repeatable function.
Less assembly work.
Consistent driving performance
Repeatable gas delivery supports consistent driving performance in the matched nailer system.
Predictable shot yield
Metering is designed for a consistent usable number of shots per cartridge, rather than wasting gas through excessive dosing.
Avoid dosing-related malfunctions
The improved coordination addresses the previously described malfunctions caused by excessive gas delivery.
−33%assembly time
In the development project described, KTH Yildiz reports a 33% reduction in assembly time. Fewer individual parts and their precise interaction connect functional performance with manufacturing effort.
Experience that carries forward
From an engineering project
to a company-wide approach.
The ADK project represents the approach KTH Yildiz still brings to plastic parts, tooling and manufacturing processes today: the function of the customer’s product is the starting point.
According to KTH Yildiz’s project account, the redesigned metering system was presented in Hilti’s quality-control process.
