Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If physical models (cardboard/wood) are used for functional testing, then the system function can be tested, but the cost, time, and space requirements increase significantly
Solution Approach 1:
The patent creates a virtual 3D model that replicates the physical system's geometry and behavior, allowing functional testing without constructing physical models. The virtual model is linked to real-world coordinates through 3D position measurement, enabling accurate simulation while eliminating material costs and construction time.
Solution Approach 2:
The patent replaces physical mechanical models with a virtual reality-based system that uses 3D measurement technology and virtual rendering. Instead of manipulating physical cardboard or wood models, users interact with virtual representations through head-mounted displays, substituting mechanical construction with digital simulation.
2Measurement precision
If a complete real model is constructed for functional testing, then accurate system representation is achieved, but material and space requirements increase
Solution Approach 1:
The patent creates a virtual copy of the physical system that maintains geometric and functional accuracy without consuming physical materials. The virtual 3D model replicates the system's structure and behavior, allowing precise measurement and testing while eliminating the need for physical model materials.
Solution Approach 2:
The patent transitions from physical 3D space to virtual 3D space, allowing the system to be represented and tested in a digital dimension. This dimensional transition enables accurate system representation without the material constraints of physical construction.
3Ease of operation
If physical models are used for testing, then haptic feedback is available, but flexibility and ergonomic adjustments are limited
Solution Approach 1:
The patent implements a dynamic virtual model that can be easily modified and adjusted without physical reconstruction. The virtual system allows real-time changes to testing scenarios, ergonomic parameters, and system configurations, providing both haptic feedback through the interface and unlimited adaptability to different testing requirements.

AI summary
A method for testing the function of a system (1). In the method, real models (7, 8) of details of a virtual 3D model (39) of the system are created, with the spatial position and orientation of these real models being captured by a 3D measuring device (11) during the function testing. The determined orientations and positions can be used to manipulate virtual objects (3, 4) in the 3D model (39) in order to display a visual impression (20) in a virtual reality of handling or manipulating the real models (7, 8).
