Mounting Of Arm Assemblies TRIZ Cases
- Asymmetric Load Beam Nesting for Shock-Safe Head Stack Assemblies
Asymmetric nested load beams increase head stack clearance during shock events, reducing metal contact, particle generation, and drive failure risk.
- Suspension Assembly Dimples for Reliable Swaging on Uneven Baseplates
Rounded dimples establish a three-point contact plane, helping actuator arms swage reliably despite baseplate flatness variations.
- Actuator Comb Stepped Bore Reduces Friction During Assembly
A stepped inner bore in an actuator comb reduces friction when force fitting a pivot-bearing assembly.
- Actuator Mechanism for Multi-Surface HDD Head Access
An elevator mechanism moves a head stack assembly vertically along a shaft, allowing fewer heads to access multiple disc surfaces and improving storage density.
- Shared Disk Configuration in Multiple Actuator Hard Disk Drives
Asymmetric disk spacing and suspension tail biasing resolve mechanical constraints while maintaining consistent head-gimbal assembly z-heights across all arms.
- Disk Drive Base Plate Protrusion Design for Thin Arm Connection
Segmented protrusions interlock with arm attachment holes to secure the base plate, reducing arm thickness without compromising connection strength.
- Magnetic Storage Pivot Carriage Friction Fit Design
A magnetic storage pivot uses a lobe-shaped carriage opening to form a friction fit, reducing thermal expansion issues while maintaining rotational stability.
- Reduced-thickness Baseplate for Data Storage Z-height Minimization
A baseplate with a flange having different uniform thicknesses and a protruding boss tower minimizes z-height while stabilizing actuator arm attachment.
