wedge

Active wedge region

Record the region whose increasing thickness is intended to create separation, contact force or restraint.

1. Which faces form the working taper, and in which direction does effective thickness increase? definition
2. Does the object's intended function depend on advancing this taper, or is its wedge-like shape incidental? boundary

Usable taper envelope

Record entry thickness, thickness profile, bearing width and the portion of travel available for working contact.

1. What are the entry thickness, taper angle or profile, and effective width at the intended engagement? measurement
2. Where must insertion stop because the taper ends, a shoulder interferes or the receiving space runs out? boundary

Engaged contact pair

Record the objects bearing on the wedge, the engaged face regions and any unintended edge contact.

1. Which objects contact each working face, and where are the actual bearing regions? measurement
2. Does the proposed orientation produce the intended separation or restraint without unsupported twisting or edge loading? action

Driving and withdrawal features

Record how force may be applied to advance or retrieve this wedge, including access constraints.

1. What instructions or design evidence establish whether the wedge may be struck, pressed, hand-inserted or drawn by a mechanism? provenance
2. Which face, head, hole or other feature accepts driving or extraction force, and will it remain accessible after insertion? action

Supported load and displacement

Record substantiated limits for the proposed role without assigning an unsupported universal capacity.

1. What source establishes allowable loading, insertion force or displacement, and what material, contact and engagement conditions does it assume? provenance
2. What load, engagement depth and required movement describe the proposed use? measurement
3. Does the proposed use remain within the evidenced conditions, or does it require further assessment? action

Retention basis

Record how position is maintained and whether the supporting evidence applies to current surfaces and loading.

1. Is retention supplied by a positive restraint, assessed frictional contact or an unverified assumption? definition
2. What evidence addresses retention under the relevant surface condition, vibration and changes in load direction? provenance
3. What restraint or operating restriction is required if migration cannot be ruled out? action

Damage affecting wedge action

Record defects by location and their implications for entry, bearing, driving and retention.

1. What rounding, cracking, mushrooming, crushing, bending or surface contamination is present at the working and driving regions? measurement
2. Which documented acceptance criteria determine whether those observations permit reuse, repair or retirement? provenance

Release dependencies

Record the supported load, restraint or stored deformation that may change when the wedge is removed.

1. Which objects could move, close, fall or spring back as wedge engagement decreases? boundary
2. What unloading, substitute support or restraint must be established before withdrawal? action
3. What evidenced extraction method applies if the wedge is jammed or its normal withdrawal feature is inaccessible? action
