Rigid Coupling Board Layout for Multi-Direction Storage Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coupling boards in printing devices face issues with abnormality, such as detachment or deformation, when two units like HDDs are attached from the same direction, making it difficult to install additional units without causing damage.
Innovation Solution
A rigid coupling board with first and second connectors oriented in different directions allows for direct coupling of storage devices, along with a production method that includes fixing these units in distinct orientations to minimize force application and reduce abnormality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If two units are attached to the coupling board from the same direction, then the coupling board can accommodate multiple storage devices, but the coupling board may detach or deform due to large applied force
Solution Approach 1:
The patent transitions from attaching both connectors in the same direction (one-dimensional arrangement) to attaching connectors in different directions (multi-dimensional arrangement). Specifically, the first connector is attached from a first direction while the second connector is attached from a second direction that differs from the first direction, thereby distributing mechanical stress across different spatial dimensions and preventing concentration of force that causes detachment or deformation.
2Ease of manufacture
If two units are attached to the coupling board from the same direction, then the installation process is simple, but it causes abnormality in the coupling board such as detachment or deformation
Solution Approach 1:
The patent modifies the attachment arrangement by introducing directional diversity. Instead of both connectors being attached from the same direction (simpler but problematic), the first connector is attached from a first direction and the second connector from a second direction. This multi-directional approach maintains reasonable installation simplicity while fundamentally resolving the reliability issue by distributing mechanical loads.
3Reliability
If connectors are oriented in different directions on the coupling board, then the coupling board reliability improves, but the device complexity increases
Solution Approach 1:
The patent employs asymmetric arrangement of connectors on the coupling board. The first connector and second connector are positioned and oriented differently relative to each other, with the first connector attached from a first direction and the second connector from a second direction. This asymmetric configuration optimizes mechanical stress distribution and improves reliability while avoiding the need for completely complex symmetric multi-directional arrangements.
