1Productivity
If 3D modeling simulation is used to calculate inserting and removing forces, then design efficiency is improved and prototype production is reduced, but calculation complexity and computational resources increase
Solution Approach 1:
The patent performs force calculations during the design stage using 3D modeling before prototype production. By preliminarily simulating the inserting and removing forces on virtual models, the system identifies design issues early, avoiding the need for multiple physical prototypes and thereby improving design efficiency despite the computational complexity involved.
2Device complexity
If contact surfaces are predefined for force calculation, then calculation process is simplified, but measurement precision and accuracy of force values deteriorate
Solution Approach 1:
The system automatically identifies and determines contact surfaces between the first and second objects during the simulation process, without requiring manual predefinition by the user. The calculation unit autonomously analyzes the 3D models to find where contact occurs, thereby maintaining calculation process simplicity while achieving high measurement precision through automated surface detection.
3Productivity
If inserting and removing forces are not calculated at design stage, then design process is simpler and faster, but product quality and force optimization deteriorate
Solution Approach 1:
The patent calculates inserting and removing forces during the design stage and uses this information as feedback to optimize the design. The calculation results provide quantitative feedback on whether the forces are within acceptable ranges, allowing designers to adjust parameters and iterate on designs efficiently, thereby maintaining both design speed and product quality through informed decision-making.
