Wedgesupported

Wedgesupported is a design concept describing a support system that uses wedge-shaped elements to stabilize and lock an object in place. The sloped faces transfer vertical loads into normal forces at the contact surfaces, generating friction that resists movement. This arrangement yields adjustable, tool-free locking in many applications.

Key factors are wedge angle, contact area, and preload. Changing these parameters adjusts clamp force and stiffness. Systems may use a single wedge or multiple wedges arranged symmetrically to maintain stability under uneven loads.

Common uses include furniture and cabinetry for adjustable feet or anti-tip supports, portable scaffolds and fixtures in fabrication, and certain rapid-clamp mechanisms in machining or robotics. Wedge-supported arrangements can provide quick stabilization without relying on threaded fasteners at the contact interface.

Advantages include simplicity, low fastener count, and easy adjustability. Limitations include sensitivity to surface finish and wear, finite load capacity before slip, potential creep under sustained load, and a need for precise alignment and geometry. The performance of a wedge-supported system depends on the quality of contact surfaces and the chosen wedge geometry.

Materials commonly used range from wood and metal to durable polymers, chosen for compatibility with the working friction. Proper lubrication, surface treatment, and controlled preload help maximize performance and longevity. Designers also consider thermal effects, material fatigue, and installation tolerances to ensure reliable behavior across operating conditions.
