Peripheral Riser Latch Assembly for Smooth Cage Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing riser cages in information handling systems often have latches that make it difficult to install and remove, and can catch on other components during the installation and removal process.
Innovation Solution
A sliding peripheral mounting system with a latch component that includes a pin engagement feature and a travel control feature, allowing the latch to move between locked and unlocked positions, facilitating easy installation and removal of riser cages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional latch mechanism is used in riser cages, then the latch can secure the riser cage in place, but the latch becomes difficult to operate and may catch on other components during installation and removal
Solution Approach 1:
The latch mechanism is divided into separate functional components: a latch body, a pin engagement feature, and a travel control feature. This segmentation allows each component to perform its specific function independently, reducing overall complexity while maintaining secure locking capability. The pin engagement feature can be easily inserted and removed from the latch body, facilitating simple operation.
Solution Approach 2:
The latch mechanism incorporates a travel control feature that enables dynamic movement between locked and unlocked positions. This dynamic capability allows the latch to transition smoothly between states without catching on components, improving ease of operation while maintaining security when locked.
2Reliability
If a secure latch mechanism is implemented to prevent accidental disengagement, then the riser cage remains firmly secured, but the installation and removal process becomes more difficult and time-consuming
Solution Approach 1:
The latch mechanism is designed with a pre-configured pin engagement feature that aligns automatically during insertion. The travel control feature is pre-set to engage the pin at the appropriate position, ensuring secure locking without requiring complex manual manipulation. This preliminary configuration maintains reliability while reducing installation time.
Solution Approach 2:
The latch mechanism incorporates self-aligning and self-engaging features that automatically secure the riser cage without requiring complex manual operations. The pin engagement feature and travel control feature work together to provide secure locking through simple insertion and removal actions, maintaining reliability while minimizing time loss.
3Volume of moving object
If the latch mechanism is designed to accommodate limited space within the riser cage, then it fits within the constrained environment, but the latch becomes harder to access and operate
Solution Approach 1:
The latch mechanism is designed with localized features that optimize both size and accessibility. The pin engagement feature and travel control feature are positioned and dimensioned to fit within the limited space of the riser cage while maintaining sufficient accessibility for manual operation. The compact design does not compromise operational ease.

AI summary
A peripheral mounting system. The peripheral mounting system includes a riser tray housing; and, a latch component, the latch component including a latch main housing portion; a pin engagement feature physically coupled to the latch main housing portion; and, a travel control feature physically coupled to the latch main housing, the travel control feature allowing the latch component to move in the peripheral mounting system between a locked position and an unlocked position.
