Develop a Self Calibrating, 2 Channel, High Speed Sensor
The supplier approached Dynazign to determine whether they could improve the existing design in terms of performance, functionality and manufacturability.
In addition to the new requirements, the supplier was under a severe time constraint to deliver a working prototype to its customer. Based on previous contact, Dynazign was approached with the opportunity to develop the sensor provided we could deliver sixty functioning production prototypes to the end customer within three calendar weeks. That is, design, material acquisition, firmware design, assembly and test.
After rapid and exhaustive analysis, we determined the crucial milestones in the critical path. Some of the most important items were:
This resulted in an unusually highly expedited effort with dependencies outside the direct control of Dynazign. Despite this circumstance, Dynazign extracted commitment from each of its vendors who played a vital role in the critical path.
Packaging posed an equally challenging proposition. Availability of space was severely limited for both component placement and height. This coupled with the delicate nature of component placement relationships of the switch mode power supply was overcome through out of the box thinking in conjunction with 3-D modeling techniques.
Another area of substantial innovation involved the addition of auto calibration routines to the firmware. This increased the practical functionality of the unit by allowing the device to run longer between lens cleanings. This is especially important in the pharmaceutical environments where a considerable amount of dust is created by product transport.
the end, the overall performance of the device was ultimately improved
by over a factor of two in both sensitivity and speed including an additional
channel of operation. In fact, the very system the sensor was designed
for could not out run the response in any mode of operation,
thus exceeding the specifications. This was not the case for the previous
