Collision Check

Error-Free Digital Prototypes Thanks To Clash Detection

Collision checking, also known as clash detection, is an indispensable part of modern product development. It ensures that components or component groups of a digital prototype fit together seamlessly, without unwanted collisions or overlaps. By using specialised software and powerful algorithms, potential geometric problems are detected and rectified at an early stage - a decisive advantage for ensuring product quality and avoiding costly errors.

Improve the Quality of Virtual Prototypes, Reduce Development Costs

The integration of Clash Detection enables efficient process optimisation by ensuring that products are delivered on time and within budget. This integration into existing development processes can be achieved in various ways. Firstly, it is important to educate the relevant teams and employees about the importance and operational added value. Then, specific process steps should be defined to integrate the collision checks into the development workflow, such as defining test times during development or defining the tasks in the team. Finally, it is important to implement a suitable software solution such as Quality Monitor.

Collision checks are already established in various industries such as automotive or aerospace: their purpose is always to uncover undetected collisions or bottlenecks so that the product fits together flawlessly in the end and necessary functional clearances, e.g. for heat transfer or movements, do not lead to problems during operation.

Calculate Collisions, Avoid Geometric Conflicts

Technological expertise meets practical experience: invenio Virtual Technologies (invenio VT) ensures conflict-free digital prototypes with its solutions in the field of collision testing and clash detection. All interfaces (contacts, overlaps or distance violations) between the components are analysed and examined for problems. In addition to static clash detection, invenio VT also offers dynamic clash detection to quickly and reliably detect conflicts during movement. In both use cases, the focus is on analysing 3D data and large volumes of data (big data).

The leading algorithms for clash detection from invenio VT are always combined with technical system support, such as Quality Monitor. The neighbourhood search determines all neighbouring components and identifies which component has a relationship with another component. Inheritance ensures that relations that have been evaluated once are not presented again unless they change.

The experts analyse the calculation results and decide together with the responsible designers on the customer side how the geometric conflicts can be resolved. The end result is a collision-free product, clearances are maintained and the current maturity level of the product is correctly displayed on a daily basis. Invenio VT's own artificial intelligence provides the decisive added value.

Ideally, the Process that Accompanies Development Comprises four Relevant Building Blocks:

  • PDM system: Storage of the CAD data to be evaluated – usually by the client – in a PDM system
  • Geometry checking software (Quality Monitor): direct access to the data (CAD and structure) and calculation of the relationships between the components
  • Results management: logical and meaningful display of the relations with documentation after the visual inspection
  • Visualisation tool: manual inspection, evaluation and subsequent documentation in the results management tool

Frequently Asked Questions about Collision Checking and Clash Detection

Collision checking or clash detection is a process in which product development checks whether different components of a virtual model conflict with each other, e.g. due to overlaps or insufficient distances.

Clash detection is crucial for quality assurance in product development. Ultimately, the integration of clash detection into the development process enables effective error detection and correction, resulting in improved product quality, shorter development times and lower costs.

There are specialised leading software solutions such as Quality-Monitor, which are used for collision checks of large amounts of data in combination with PDM (Product Data Management) systems.

The individual CAD data is built up into a virtual product in a PDM system, then the geometry checking software calculates and analyses the data and identifies relationships or potential problem areas between the components. The results are then analysed by experts and tracked as part of results management.

The results are then analysed by experts and tracked as part of results management.

The biggest challenges include handling large amounts of data for complex products, efficient evaluation and avoiding recurring results of geometric relationships. This means that evaluations that have already been carried out should only be presented to users again if something has changed in the geometric conflict. Using high-performance, intelligent algorithms, we offer the right solutions and answers to these challenges.

Yes, the process of collision checking can be automated, especially data collection, data calculation and data analysis. Manual checking and evaluation by experts is still widespread. This is often very time-consuming, especially with large amounts of data. With the help of artificial intelligence, the manual effort can be significantly reduced.

It can accelerate the development cycle by identifying errors at an early stage and enabling corrections to be made, which contributes to a faster time to market for products and reduces costs.

If a collision is detected, the designer and engineer work together to find a solution, be it through design changes or adjustments to the positioning of the affected components.

A live collision check constantly monitors all design changes and reports as soon as a conflict arises.
