First Claim
Patent Images
1. A diagnostic device, comprising:
- a housing having an upper housing part and a lower housing part;
a display module mounted in the housing and comprising a fulcrum connected to the lower housing part;
a circuit board positioned between the display module and the lower housing part; and
a cantilever arm extending from a first section of the display module in a direction away from the fulcrum and away from a periphery of the display module, a contact portion of the cantilever arm being biased against the circuit board or the lower housing part;
wherein the bias of the cantilever arm produces a force that is transferred to a second section of the display module remote from the first section.

Abstract
The present invention provides an innovative means for efficient and secure component assembly and for ensuring secure electrical connections in a small diagnostics device where available space for fasteners is limited. In one embodiment, principles of leverage are employed to produce a force at a location where space is available. The force is transferred to a different location of the assembly where it is used to maintain secure connections between components.

14. A diagnostic device, comprising:
-
a housing having an upper housing part and a lower housing part; a display module mounted in the housing and having a first end and a first electrical connector remote from the first end; a lever arm extending from the first end and producing a force remote from the first electrical connector; a circuit board positioned between the display module and the lower housing part and having a second electrical connector connected to the first electrical connector; and a fulcrum connected to the display module and located remote from the first end, wherein the force is transferred from the lever arm through the fulcrum to the first and second electrical connectors to bias the first and second electrical connectors together. - View Dependent Claims (15, 16, 17)

18. A method of assembling a diagnostic device having upper and lower housing parts, a display module, and a circuit board, the method comprising:
-
(a) inserting the circuit board into the lower housing part; (b) placing the display module over the circuit board, such that a lever arm extending from a first section of the display module is biased against the circuit board or the lower housing part; (c) fastening the circuit board to the lower housing part and thereby creating a fulcrum, wherein a force is transferred from the lever arm through the fulcrum to a second section of the display module that is remote from the first section, the force biasing the second section of the display module against the circuit board or the lower housing part; and (d) securing the upper housing part to the lower housing part. - View Dependent Claims (19, 20, 21, 22, 23)

24. A diagnostic device, comprising:
-
a housing having an upper housing part and a lower housing part; a module mounted in the housing and connected at a connection point to the lower housing part; a circuit board positioned between the module and the lower housing part; and a lever arm configured to pivot about the connection point and having a first end extending from a first section of the module in a direction away from the connection point and away from a periphery of the module, the first end of the cantilever arm being biased against either the circuit board or the lower housing part such that the bias of the lever arm produces a force that is transferred to a second section of the module remote from the first section. - View Dependent Claims (25, 26)
