Electro-Mechanical Brake Caliper Layout for Compact Force Sensing

The patent applies dimensional change by relocating the pressure sensor from a conventional axial arrangement to a radial arrangement within the brake caliper body. The pressure sensor is positioned to detect pressure through the brake disc thickness direction (radial direction), rather than along the axial direction of the brake apparatus. This dimensional reconfiguration reduces the axial size while maintaining pressure detection functionality, enabling adaptation to limited wheel space in vehicles.

The patent implements nesting by partially accommodating the pressure sensor within the brake caliper body. The pressure sensor is positioned such that part of it is received within the caliper body structure, creating a nested arrangement. This reduces the exposed portion of the sensor, minimizing axial size while maintaining detection precision. The nested design also protects the sensor while allowing for reasonable installation accessibility.

The patent applies local quality by using pressure sensors with different measurement scales positioned at different locations within the brake system. Each sensor is selected with a specific measurement scale appropriate for its local measurement requirements - for example, higher precision sensors for critical braking force measurement points and lower precision sensors for less critical positions. This localized optimization achieves high overall braking precision without requiring all sensors to be high-precision, thereby controlling device complexity.
