Ruler SSD Jam Mechanism for Misalignment-Tolerant Plugging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The integration of plugable components in cloud computing and data centers faces challenges due to misalignment issues when trying to maximize functionality within minimal space, particularly with solid state drives (SSDs) in ruler form factor, which can lead to jamming and prevent easy unplugging.
Innovation Solution
A self-adjusting jam mechanism with a ramped leading edge and toothed trailing edge is designed to fit into varying opening sizes, ensuring secure plugging and preventing backward motion by locking into place as the SSD slides into the connector, allowing for alignment adjustments and secure engagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed jam mechanism is used to prevent backward motion, then reliability of plugging is improved, but adaptability to misalignment is worsened
Solution Approach 1:
The jam mechanism transitions from a fixed structure to a dynamic one by incorporating a spring-loaded tip that can move between retracted and extended positions. This allows the jam to adapt its position based on alignment conditions during insertion, then lock into place to prevent backward motion, thus resolving the contradiction between reliability and adaptability.
Solution Approach 2:
The jam mechanism changes its physical state through spring force, allowing the tip to extend or retract based on alignment requirements. When misalignment is detected, the spring allows retraction for adjustment; when aligned, the spring extends the tip to lock and prevent backward motion, thereby achieving both adaptability and reliability.
2Adaptability or versatility
If a self-adjusting jam mechanism is used, then adaptability to misalignment is improved, but device complexity is worsened
Solution Approach 1:
The spring-loaded jam mechanism is designed to automatically adjust itself based on alignment conditions during insertion. The spring force enables the tip to extend or retract without external control, making the system self-regulating and reducing the need for complex control mechanisms, thus achieving adaptability with minimal added complexity.
3Reliability
If the jam tip is always extended to prevent backward motion, then plugging reliability is improved, but ease of operation for removal is worsened
Solution Approach 1:
The jam tip dynamically changes position based on operational phase: during insertion, it extends to lock and prevent backward motion (reliability); during removal, it retracts to allow easy extraction (ease of operation). This dynamic behavior resolves the contradiction between maintaining security and enabling easy removal.
Solution Approach 2:
The spring mechanism is pre-loaded to automatically retract the jam tip when removal force is applied, preventing the tip from interfering with the removal operation. This preliminary anti-action ensures that the jam tip does not hinder removal while still providing locking during insertion.

AI summary
An apparatus is described. The apparatus includes an electronic component to be plugged into an electronic system. The electronic component includes a housing. The housing includes a jam. The jam is to push through a first opening in a bottom of the housing and a second opening in a surface when the first and second openings are at least partially aligned. The surface is a mechanical component of the electronic system that the electrical component is to slide upon when being plugged into the electronic system. The jam includes tooth edges to engage with an edge of the second opening.
