Sampling Device Deformable Drive Bracket for Bulk Materials

The patent applies beforehand cushioning by introducing a deformable element (such as a spring or elastomer) between the drive bracket and the base that can absorb and dissipate mechanical energy from unexpected obstacles. This cushioning element is pre-installed to protect the rigid mechanical components from damage when the probe encounters obstacles during operation, allowing the device to withstand external forces without catastrophic failure.

The patent applies parameter changes by transforming the drive bracket from a completely rigid structure to a semi-flexible structure with controlled compliance. The deformable element introduces a specific mechanical parameter (flexibility or compliance) that allows the bracket to deform under external forces while maintaining operational stability during normal operation. This parameter change enables the bracket to absorb shock loads without compromising its ability to transmit driving forces effectively.

The patent applies the principle of cheap short-living objects by using a deformable element that can be easily replaced when worn or damaged. Rather than using complex mechanical bumpers that wear contact surfaces, the solution employs a simple elastomeric or spring-based element that absorbs wear through its material properties and can be quickly swapped out without affecting other components. This reduces maintenance complexity and repair time.

The patent applies self-service by designing a protection system that automatically responds to obstacle detection without requiring complex sensor arrays or control logic. The deformable element provides inherent mechanical feedback that can be detected by simple limit switches or position sensors already present in the drive system, allowing the device to protect itself through its own operational parameters rather than adding independent monitoring systems.
