Shock-Absorbing Container for Hot-Swappable Storage Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for protecting hot-swappable information-storage devices from physical shocks and electrostatic discharge during shipment, handling, and operation are either expensive or unsuitable for removable devices, as they require removal from containers for installation and lack effective shock absorption for frequent insertions and removals.
Innovation Solution
A shock-absorbing container made from static-dissipative, resilient plastic with a foam packing material that maintains the device's position and allows direct connection to a drivebay, using a Serial ATA connector for alignment tolerance and optional thermally conductive materials for cooling, enabling protection and operation without interposers or complex alignment mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the device is removed from the container for installation, then the device can be installed in the drivebay, but the device is exposed to physical shocks and handling damage during removal and installation
Solution Approach 1:
The storage device remains nested within the container during installation, with the container itself being inserted into the drivebay. The device is protected inside the container while the container serves as the interface with the drivebay, eliminating the need to expose the device during installation.
Solution Approach 2:
The container acts as an intermediary between the storage device and the drivebay. Instead of directly installing the device into the drivebay, the container mediates the installation process by providing a protected interface that connects to the drivebay while keeping the device shielded inside.
2Reliability
If a rigid container is used to protect the device from shocks, then the device is protected from physical damage, but the container cannot accommodate frequent insertions and removals without damage
Solution Approach 1:
The container uses a flexible resilient foam material that can deform to absorb shock forces while allowing repeated insertions and removals. The flexible nature of the foam enables the container to withstand the mechanical stresses of hot-swappable operations while maintaining shock protection.
Solution Approach 2:
The container material properties are optimized to balance shock absorption and flexibility. The foam material's density, hardness, and elasticity parameters are selected to provide adequate shock protection while allowing the container to flex during frequent insertions and removals without structural damage.
3Productivity
If the device is continuously connected to the drivebay for hot-swapping, then the device can be frequently installed and removed, but the device is exposed to electrostatic discharge and physical shocks
Solution Approach 1:
The resilient foam material provides beforehand cushioning by being pre-configured to absorb shock forces and provide electrostatic protection. The foam is positioned around the device in advance to create a protective barrier against harmful factors before any shock or ESD event occurs.
Solution Approach 2:
The container uses composite material construction combining resilient foam with conductive or static-dissipative materials to simultaneously provide mechanical shock absorption and electrostatic discharge protection. This composite structure allows frequent hot-swapping while protecting against multiple harmful factors.
4Ease of operation
If a complex alignment mechanism is used to maintain device alignment during hot-swapping, then the device can be frequently installed and removed with proper alignment, but the manufacturing cost and device complexity increase
Solution Approach 1:
The container's foam material self-adjusts to maintain proper alignment of the device with the drivebay during insertion and removal. The resilient foam deforms to accommodate alignment tolerances and guide the device into the correct position without requiring external alignment mechanisms.
Solution Approach 2:
The flexible foam container naturally conforms to the drivebay geometry and provides self-alignment through its deformable structure. This eliminates the need for rigid alignment features, guides, or complex mechanical positioning systems.

AI summary
A method and article of manufacture for protecting a device from damage caused by physical shocks during shipment, handling, and use of the device are disclosed. A shock-absorbing container is provided with a foam material provided around the device when it is placed in the container. An opening in the container is aligned with respect to the device so as to expose a physical interface of a bay to the physical interface of the device in the container. The device and container are proportioned so that when the container, containing the device, is slid into a bay of a device array or data processing system, the physical interface directly connects with a mating physical interface in the bay without requiring an interposer between the physical interface of the device and the physical interface of the array or data processing system.
