Tool-Actuated Slide Latch for Cold-Service Resource Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information handling systems fail to differentiate between cold-service and hot-service resources, leading to premature removal of cold-service resources, which can cause abrupt system shutdown and data loss.
Innovation Solution
A tool-actuated slide latch mechanism with a lever arm and slide latch that requires a tool to transition from an engaged to a disengaged position, ensuring that cold-service resources can only be removed when the system is powered down.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a standard latch mechanism is used that allows easy removal, then ease of operation is improved, but reliability deteriorates due to premature removal of cold-service resources
Solution Approach 1:
A tool actuator serves as an intermediary between the user and the latch mechanism. The latch includes a recess specifically designed to receive a removal tool, which then transmits force to the latch lever to trigger disengagement. This intermediary tool requirement creates a deliberate barrier that prevents accidental or premature removal while maintaining controlled access when the proper tool is available.
2Manufacturing precision
If cold-service and hot-service resources appear similar, then manufacturing precision is improved by using identical components, but difficulty of detecting and measuring worsens because users cannot differentiate between resource types
Solution Approach 1:
While maintaining overall component standardization, the latch mechanism introduces a localized distinctive feature: a specifically shaped recess requiring a matching removal tool. This local quality difference allows users to identify cold-service resources that require tool-actuated removal, differentiating them from hot-service resources that can be removed without tools, while still using standardized latch components throughout the system.

AI summary
A slide latch mechanism may include a lever arm and a slide latch. The slide latch may be configured to mechanically engage with the lever arm in a first position and mechanically disengage with the lever arm in a second position, and the slide latch may be further configured such that a tool is required to slide the slide latch from the first position to the second position.
