Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional hard disk rack assembly is used, then the rack can be assembled, but the assembly process is cumbersome and requires substantial effort due to protrusions and significant weight
Solution Approach 1:
The tray module employs dynamic connecting rods that can rotate and translate along guiding portions, transforming the static assembly process into a dynamic motion sequence. The connecting rods rotate from a horizontal position to an inclined position, enabling the carrier body to move from a lower assembly position to an upper operational position, thereby simplifying assembly operations and reducing time consumption
Solution Approach 2:
The connecting rods serve as intermediary elements between the carrier body and the chassis. These intermediaries transfer the lifting motion from the operating ends of the second connecting rods to the carrier body through pivotal connections, enabling easy positioning without direct manual handling of the heavy carrier body
2Ease of operation
If traditional hard disk rack assembly is used, then the rack can be assembled, but substantial effort is required due to the significant weight of the loaded rack
Solution Approach 1:
The elastic element acts as a counterweight mechanism by providing an upward elastic force that opposes the gravitational force on the carrier body. When the connecting rods are in the inclined position, the elastic element is compressed or stretched to store potential energy, which then assists in lifting the carrier body, reducing the manual force required during assembly
Solution Approach 2:
The dynamic motion of the connecting rods along the guiding portions creates a mechanical advantage system. As the connecting rods rotate from horizontal to inclined positions, they leverage the geometry of the guiding portions to transform small input forces at the operating ends into larger lifting forces on the heavy carrier body, significantly reducing the effort required
3Ease of operation
If the carrier body is moved directly without guiding portions, then movement is possible, but the movement cannot avoid barriers and structures in the chassis
Solution Approach 1:
The guiding portions act as intermediary structures that mediate between the carrier body and the chassis barriers. These guiding portions provide predefined motion paths that automatically navigate around obstacles and structural elements in the chassis, allowing the carrier body to move from the assembly position to the operational position without direct intervention to avoid barriers
Solution Approach 2:
The guiding portions are designed with both horizontal and inclined sections that dynamically adapt to the motion requirements. The horizontal section guides the connecting rods during initial movement, while the inclined section guides them during the lifting phase, creating a continuous smooth path that avoids all chassis barriers without requiring complex external guiding mechanisms
