Deep Dive: Optical Inline Measurement Technology –
System Understanding for Industrial Serial Production Applications

Structured Project Phases Reduce Learning Curves

Project phases and learning curves of measurement systems describe the typical development and maturation processes that an inline measurement solution goes through – from the initial concept idea to stable integration into serial production. In industrial applications, learning curves arise not only at the technological level, but particularly in the interaction between measurement technology, the process environment, and quality requirements.

QuellTech Process

Typical Project Phases of an Optical Inline Measurement Solution

  1. Requirement definition: Analysis of quality criteria, tolerance requirements, process conditions, and cycle times.
  2. Feasibility analysis / Proof of Concept: Validation of the measurement principle under controlled conditions.
  3. System design: Definition of sensors, optics, mechanics, interfaces, and feature logic.
  4. Integration and pre-series: Integration into the production line and validation under real environmental conditions.
  5. Serial production and optimization: Stabilization, drift monitoring, and fine adjustment of feature definitions and decision logic.

Learning Curves in the Industrial Context

In early project phases, the primary focus is often on the basic measurability of a feature. Only during real production operation do additional influencing factors become apparent – such as handling variation, component variation, or environmental conditions. These factors often lead to iterative adjustments in feature extraction, filtering strategies, or referencing methods.

Risks of Unstructured Project Development

• Underestimation of real process variation
• Excessive focus on laboratory performance
• Unclear definition of decision-relevant features
• Lack of alignment between measurement technology and process logic
• Long stabilization phases after production start

Systematic Management of Learning Curves

A structured development approach considers serial production conditions from the outset. This includes early testing under realistic environmental conditions, clear definition of quality decisions, and step-by-step validation in the production environment. The goal is to address project-specific learning processes as early as possible and make stabilization during production ramp-up predictable.

QuellTech follows a system-oriented project approach in the development of inline 3D laser systems. Process conditions, cycle times, and interfaces are already considered during the concept phase. Through structured integration and validation close to serial production conditions, the learning curve can be controlled and stabilization in serial operation accelerated. The focus is not on isolated demonstrators, but on industrially robust solutions.
