Foldable Assembly Pivot Mechanism for Memory Module Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The tight arrangement of memory module slots in existing foldable assemblies leads to interference between memory modules when the assembly is in either the closed or open position, making assembly inconvenient due to the lack of differential rotational resistance to manage module positioning effectively.
Innovation Solution
A foldable assembly with a pivot assembly comprising first and second pivot members having axial holes with recesses of different angles and protrusions on the outer surface, providing varying rotational resistances to control the pivoting direction and prevent module interference, allowing for controlled positioning of memory modules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If memory module slots are tightly arranged to increase the number of memory modules, then the capacity of the memory modules is increased, but memory modules interfere with each other when the assembly is in closed or open position
Solution Approach 1:
The pivot assembly enables dynamic adjustment of the expansion plates between closed and open positions, allowing the system to adapt its configuration based on operational needs. The differential rotational resistance ensures controlled movement that prevents memory module interference while maintaining tight arrangement.
Solution Approach 2:
The recesses with different angles on the axial holes create different rotational resistances for clockwise and counterclockwise directions. This parameter change in the geometric configuration allows one expansion plate to pivot before the other, preventing memory module interference while maintaining tight arrangement.
2Quantity of substance
If memory module slots are tightly arranged to increase the number of memory modules, then the capacity of the memory modules is increased, but assembling memory modules becomes inconvenient
Solution Approach 1:
The pivot assembly allows the expansion plates to be dynamically adjusted between closed and open positions during assembly. This dynamic capability enables assembly personnel to access memory modules more easily by opening the plates, then close them securely after installation, significantly improving assembly convenience.
Solution Approach 2:
The pivot assembly can be used to preliminarily position and align the expansion plates before final assembly. By controlling the pivoting motion through differential rotational resistance, the plates can be carefully positioned to avoid interference, making the assembly process more convenient and precise.
3Device complexity
If the first plate component and second plate component are pivoted simultaneously, then the structure is simple, but memory modules on both plates interfere with each other
Solution Approach 1:
The recesses with different angles on the axial holes create different rotational resistances for clockwise and counterclockwise directions. This parameter change in the geometric configuration allows one expansion plate to pivot before the other, preventing memory module interference while maintaining relatively simple pivoting mechanism.
Solution Approach 2:
The asymmetric design of recesses with different angles on the axial holes creates differential rotational resistance. This asymmetry ensures that one expansion plate pivots before the other during the pivoting process, preventing memory module interference while keeping the overall mechanism simple.
