PROJECT OVERVIEW:
The project is to re-engineer the UPS enclosure and integrate it into the digital radiography (DR) machine.
WORK FLOW:
Requirement:
The Requirement was to install the UPS inside the DR machine for power back up and make it easy to transport.
Concept Development:
Several concepts on the arrangement of the components of UPS were made and the most mechanically feasible design were selected.
Mechanical Engineering:
Reengineered the UPS enclosure to customize it according to the space available into the DR.
CAD:
CAD design of DR machine, UPS enclosure and all the components placed into it were made to check the components assembly, fitment and feel of the device compactness.
Prototyping:
A sheet metal fabrication of the customized UPS was made.
Assembly sequence:
The component was placed and checked the Concept, assembly interference and ease assembling.
Clearance analysis:
Integrated the UPS into the DR machine and ensure the dimensional accuracy of exact assembling of components, check the sufficient gaps between all the components and tested for EMI/EMC issue
CHALLENGES:
-
The DR machine was already design to compactly packed all the components, hence, limited space available for the battery and the UPS.
-
The new customized enclosure of UPS should not disturb the existing outer enclosure DR machine.
-
We should not keep more weight as it disturbs the centre of gravity balance of the machine.
ENGINEERING SOLUTION:
-
Created customized sheet metal enclosure & placed each component without affected EMI/EMC
-
The transformer was present in DR machine produces heat and radiation did not effect the UPS electronic.
-
The position each component in the given limited space without disturbing the outer encloure of DR machine.
-
The arrangement and orientation of the battery and keep it in the front side base to adjust the space availability at the back.
