Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional server case fixing methods require tool operation, making them inconvenient for use.
Innovation Solution
A server case latch structure featuring an upper-layer and lower-layer case with a sliding block and stopping member that can be manually operated to lock and unlock without tools, utilizing L-shaped grooves and snapping portions for secure engagement and disengagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional fixing methods with mounting screws are used, then the fixing strength is sufficient, but tool operation is required making the operation inconvenient
Solution Approach 1:
The patent replaces the traditional screw-mechanical fastening system with a snap-fit elastic mechanical system. The elastic component deforms during installation to engage with the positioning groove, eliminating the need for screwdrivers or other tools while providing sufficient fixing strength through elastic retention rather than threaded mechanical engagement
Solution Approach 2:
The elastic component automatically engages with the positioning groove through its own elastic deformation without requiring external tool assistance. The component serves itself by using its elastic properties to both install and secure the upper case to the lower case, making the entire fixing process self-contained and tool-free
2Reliability
If I-nails with locking screws or spring pins are used, then the locking reliability is improved, but the operation becomes more complex requiring multiple components
Solution Approach 1:
The patent merges the functions of multiple traditional fastening components (I-nail, locking mechanism, spring) into a single integrated elastic component. This one-piece design achieves reliable locking through the combination of elastic retention and positioning groove engagement, eliminating the need for separate locking screws or spring pins while maintaining locking reliability
Solution Approach 2:
The elastic component performs multiple functions simultaneously: it provides the locking force through elastic deformation, engages with the positioning groove for precise alignment, and serves as both the fastening element and the installation tool interface. This multi-functionality replaces several specialized components with a single versatile element
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
Enables tool-free operation for locking and unlocking the server case, reducing complexity and improving usability by allowing manual control of the locking and unlocking process.
Implementation Method 1
an elastic arm (96), provided with a hook (94) which can be snapped with the locking snapping portion (111) or the unlocking snapping portion (112) in a sliding stroke of the sliding block (9)
Implementation Method 2
the lower-layer case is provided with a sliding block return spring connected to the sliding block, and an elastic force of the sliding block return spring is configured to locate the sliding block at a snap position of the locking snapping portion with the hook
Data Source
AI summary
A server case latch structure and a server are disclosed. The structure includes: an upper-layer case including an L-shaped groove; lower-layer case having a locking snapping portion and an unlocking snapping portion; a sliding block having an elastic arm provided with a hook, wherein the hook can be snapped with the locking snapping portion or the unlocking snapping portion in the sliding stroke of the sliding block, and the sliding block has an operation portion; and a stopping member. When the sliding block moves to snap with the locking snapping portion, the stopping member is snapped with the L-shaped groove, so that the upper-layer case and the lower-layer case are locked; and when the sliding block moves to disengage the hook from the locking snapping portion, the stopping member is un-snapped locked from the L-shaped groove, and the upper-layer case and the lower-layer case are unlocked.
