Automotive door quality, especially in the areas of wind noise and water leakage is a perennial JD Power customer complaint. With the advent of infotainment systems and hands free-calling, it is of utmost importance to design and produce cars that exceed expectations in these categories. The quietness of electric vehicles necessitates elimination of wind noise now more than ever.
In the past, hidden and hard to reach/see gaps were often measured with manual, tedious or clumsy methods such as feeler gauges, friction blocks or even clay/calipers. A global automotive OEM came to Inora looking for a faster, highly accurate, digital, wireless, temperature stable system to measure hidden seal gap in car doors. This prompted the creation of the WiseGap system.
WiseGap was developed using OI Core Technology to meet and exceed the challenge of replacing manual and numerically uncertain digital methods of gap measurement. It was designed to be universally applicable across all closure types and for steel as well as non-magnetic car bodies.
WiseGap software features OI Core Technology to provide numerically certain user calibration of the system at any time. The supporting hardware is very precise and can be adapted to a number of applications within automotive and beyond to other industries, such as heavy industry, appliances and aerospace to name a few.

Customer Success Stories
Premium European Automotive OEM Implementation Of WiseGap As A Global Standard For Closure Control
While most global automotive OEM’s utilize WiseGap to some degree in their operations, one premium European brand has been unique however, making the WiseGap a global standard at multiple points in their process:
- Research And Development
- Measurement In Body Shop
- Measurement After Paint Shop
- Measurement After Trim Ship
By implementing WiseGap systematically, the OEM’s internal quality metrics showed a 35% improvement.
Ability To Better Adjust And Test Closures Dynamically In Vehicle Design And Testing
A Premium Japanese OEM wanted a faster, more accurate way to set their doors in the design phase of a model. While they previously used clay, by implementing WiseGap, they were able to have quick digital feedback in real-time in order to set and adjust their closures.
Once the closures had been set properly, the WiseGap also helped to monitor and understand closure behavior on test drives and wind tunnels to optimize closure behavior. This ultimately saved time and improved closure design/execution.
