Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Storage devices in enclosures face issues with induced shock and vibration, leading to performance degradation and reliability concerns, as existing solutions often require additional materials and manufacturing processes for shock and vibration mitigation.
Innovation Solution
The introduction of a self-biasing storage device sled with integral vertical and horizontal biasing features, utilizing a bezel design with a spring-retained latch and longitudinal members that exert force against the chassis, minimizing the impact of shock and vibration without the need for additional components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional materials and manufacturing processes are used for shock and vibration mitigation, then reliability is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent combines multiple functions into the sled structure itself. The sled includes integral biasing features (spring elements) that provide shock and vibration mitigation without requiring separate mounting components. The sled body integrates latching mechanisms and positioning features, eliminating the need for additional materials and assembly steps while maintaining reliability
Solution Approach 2:
The sled is designed to be self-contained with built-in biasing features that automatically provide shock mitigation. The spring elements are integrated into the sled structure, allowing it to self-regulate and protect storage devices without external intervention or additional components
2Stability of the object's composition
If a secure mounting mechanism is implemented, then storage device stability is improved, but ease of operation deteriorates
Solution Approach 1:
The sled incorporates dynamic latching mechanisms that can easily transition between locked and unlocked states. The biasing features provide automatic engagement during installation and easy release during removal, allowing the mounting mechanism to adapt between secure holding and convenient operation based on user action
3Object-affected harmful factors
If vertical and horizontal biasing features are integrated into the sled, then shock and vibration resistance is improved, but manufacturing precision requirements increase
Solution Approach 1:
The biasing features are designed as separate, modular elements that can be independently manufactured and then assembled into the sled. This segmentation allows each component to be produced with standard tolerances using conventional manufacturing processes, avoiding the need for high-precision integrated features while still achieving effective shock and vibration mitigation
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The self-biasing features securely mount storage devices, reducing susceptibility to shock and vibration, thereby enhancing performance and reliability while eliminating the need for extra materials or manufacturing steps.
Implementation Method 1
a spring retained between the bezel first and second portions and configured to push the latch outwardly from the bezel
Implementation Method 2
the horizontal biasing feature exerts force against the first chassis interior side surface and biases the storage device sled against a second chassis interior side surface... minimizing the impact of shock and vibration
Implementation Method 3
While pulling the storage device sled from the chassis at least one vertical biasing feature of each of first and second longitudinal members loses contact with a chassis inside surface

AI summary
A storage device sled for mounting a storage device within a chassis is provided. The storage device sled includes a bezel, which includes a first portion that is stationary relative to a storage device, a second portion vertically captured within the first portion and configured to slide between unlatching and latching positions, and a spring configured to push the latch outwardly from the bezel. The second portion includes a finger-movable member, a latch, and a horizontal biasing feature adjacent to the latch and configured to move in concert with the latch. The storage device sled also includes first and second longitudinal members, each orthogonally coupled to opposite ends of the bezel first portion and each coupled to opposite sides of the storage device. When the storage device is installed in the chassis, the horizontal biasing feature exerts force against a first chassis interior side surface and biases the storage device sled against a second chassis interior side surface.
