1. A weight measurement device comprising:
a housing;
a receiving tray;
a lever assembly configured to receive a weight force from the receiving tray and generate a collective lever force corresponding to the weight force, the lever assembly comprising a plurality of levers, wherein each lever of the plurality of levers extends from a respective first side of the receiving tray, underneath a central portion of a bottom surface of the receiving tray, towards a respective opposite side of the receiving tray, wherein each lever of the plurality of levers is at least substantially fixed to the housing at a respective first lever end and extends from the respective first lever end to a respective second lever end along a respective horizontal plane across at least a portion of an internal housing portion defined by the housing, and wherein each lever of the plurality of levers is configured to receive a partial weight force from the receiving tray at the respective second lever end, and wherein the lever assembly further comprises a lever alignment component configured to partially constrain the movement of each of the plurality of levers; and
a force sensor configured to generate force sensor data based at least in part on the collective lever force,
wherein the force sensor is configured to define a fulcrum point along each of the plurality of levers and at a point on a vertical lever alignment with the lever alignment component,
wherein a portion of each of the plurality of levers extends through the lever alignment component such that the plurality of levers is arranged in a vertical stack configuration, and
wherein the fulcrum point of each of the plurality of levers is at least substantially aligned with the vertical lever alignment axis that corresponds to a central axis of the weight measurement device.
