Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional carriers for electronic devices, such as hard disk drives, require significant force to insert or remove from cages due to protruding conductive elastic elements, leading to potential damage and increased space occupancy due to necessary clearance.
Innovation Solution
A carrier design with a main body, conductive elastic elements, and a pivotally coupled handle that allows the conductive elastic elements to protrude or retract based on the handle's position, enabling secure contact with a cage for EMI prevention while minimizing interference and damage risk.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If conductive elastic elements protrude outside the main body to contact the cage for EMI prevention, then electromagnetic interference is prevented, but significant force is required to insert or remove the carrier and the elements are prone to damage
Solution Approach 1:
The conductive elastic elements are designed to be dynamically positionable between a protruding state (when handle is engaged) and a retracted state (when handle is disengaged). This dynamic configuration allows the elements to contact the cage for EMI prevention during operation while being retracted during installation/removal to reduce required force and prevent damage.
Solution Approach 2:
The elements are preliminarily positioned in a retracted state before insertion, and automatically transition to the protruding state after insertion when the handle is engaged. This preliminary action prevents damage during handling while ensuring EMI protection is activated when needed.
2Reliability
If greater clearance is kept between the cage and carrier to prevent damage to conductive elastic elements, then the elements are protected from damage, but the cage occupies more space
Solution Approach 1:
The dynamic positioning of conductive elastic elements allows the cage design to have minimal clearance since the elements can be retracted when not in use. This eliminates the need for excessive clearance space, thereby reducing the overall volume occupied by the cage while maintaining reliability during operation.
3Stability of the object's composition
If significant force is applied to push the carrier into the predetermined position, then the carrier is securely installed, but the conductive elastic elements are easily damaged
Solution Approach 1:
The handle mechanism preliminarily positions the conductive elastic elements in a retracted state before insertion, protecting them from damage during the insertion process. After secure installation, the handle engagement causes the elements to protrude, achieving both stable installation and element integrity.
Solution Approach 2:
The retracted position of the conductive elastic elements serves as a cushioning state during insertion, preventing direct contact and potential damage. This beforehand protection ensures element integrity while still allowing stable installation to be achieved.

AI summary
A carrier includes main body, a conductive elastic element, and a handle. The main body is adapted to carrying an electronic device and has a cavity. The conductive elastic element is disposed in the cavity. The handle is pivotally coupled to the main body. When the handle locks the main body to be located in a lock position, the handle exerts force on the conductive elastic element such that the conductive elastic element protrudes outside the main body through the cavity. When the handle does not lock the main body and exert force on the conductive elastic element to be located at a release position, the conductive elastic element is located inside the main body where it does not interfere with an outside device. This allows convenient insertion and removal of the carrier relative to a cage. Accordingly, the conductive elastic element is not damaged easily.
