Engineering Contradiction Analysis
1Measurement precision
If strain gauges or load cells are used to measure braking force in the housing, then force measurement is possible, but measurement precision deteriorates due to bending moments, torsional moments, and lateral forces affecting the housing deformation
Solution Approach 1:
The housing is segmented into a measuring section and a support section. The measuring section is specifically designed to experience bending deformation proportional to the braking force, while the support section provides structural stability. This segmentation allows the measurement function to be isolated from the harmful forces affecting the overall housing structure.
Solution Approach 2:
The measuring section acts as an intermediary element between the braking device and the housing. It converts the braking force into a measurable bending deformation that is proportional to the force magnitude, while isolating the measurement process from the harmful bending moments, torsional moments, and lateral forces that affect the main housing structure.
2Measurement precision
If the measuring section is oriented orthogonal to the braking force direction, then measurement sensitivity is enhanced through bending moment conversion, but device complexity increases due to the specific geometric configuration required
Solution Approach 1:
The orientation parameter of the measuring section is changed to be orthogonal to the braking force direction. This parameter change maximizes the bending moment experienced by the measuring section for a given braking force, thereby enhancing measurement sensitivity. The measuring section is designed with specific geometric parameters (length, thickness, width) that are optimized to achieve the desired measurement range while maintaining structural integrity.

AI summary
The invention relates to a brake 1 for braking the relative movement of two parts 3, 6 to each other, wherein in particular the first part 3 is a flap, for example a door of a motor vehicle, and the second part 6 is a chassis part, for example a column of a motor vehicle, to which the flap is hinged, the brake 1 comprising: - a support section 10, 11 for supporting the brake 1 on the first part 3 and - a braking device 15 for braking a brake rod 4 connected to the second part 6 with a braking force 8 pointing in the direction of the brake rod 4.A special feature is that the braking device 15 is supported on the support section 10, 11 in the braking force direction 8 by means of an intermediate measuring section 12, 13, and the measuring section 12, 13 points in a direction orthogonal to the braking force direction 8, so that the measuring section 12, 13 experiences a bending in the braking force direction 8 due to a braking-induced support of the braking device 15 relative to the support section 10, 11, and a sensor 16 is provided for measuring the bending of the measuring section 12, 13 in the braking force direction 8.
