Development Process
Conception of the electronics and software

Ideas and Conception Analysis

development step 1

The customer's specifications, the client's ideas or even a workshop is the prerequisite for a successful start of the first important phase on the path of developing devices and solutions. The basic requirements of the customised development are defined in the specifications. The conception of the solution is receptive to different solution approaches. In the process, the engineers for electronics and information technology examine and analyse the state of technology, all innovations available on the market, competitor products and preliminary work that has already been done. At pironex, the principle is practised that the new development must not only look good but must also have many features and be producible. The costs are to be evaluated with the actual functions in the results and recorded in the specifications.

pironex GmbH fulfils the requirements according to the QM system ISO-9001.

Scope of Services for Customer-Specific Device Development

In regards to complex and functional product development, the following technical topics would be worked on:

  • Development of a concept and specifications partial or complete system
  • Draft design and usability
  • Selection and coordination of unit housing
  • Housing design and technical draft
  • Mechanical development of the device
  • Electronics development
  • Development of the embedded software
  • Development of PC software for control and evaluation
  • Backend software for data acquisition and processing
  • Frontend software for data visualisation and user interaction
  • Creation of native apps for Android/iOS

Development Process, Testing and Prototypes

The following provides a list of development steps that would mainly be used in order to plan for the work involved with a development project.

  • Drafting and Creating the Functional Specification
    • Functional requirements for the electronics have been determined
  • A-Sample:
    • Printed circuit board in the target format for the final product
    • Programming of the commissioning software
    • Commissioning and troubleshooting
    • partially functional device software
  • B-Sample:
    • Error-corrected hardware
    • Almost all functional software features are implemented
    • Functional but partially untested modules are available in small numbers
    • EMC Tests and Certifications are in progress
  • C-Sample:
    • Pre-production sample matches the design and target function
  • D-Sample:
    • Pilot series devices for field testing
  • Series
    • Product support
