Server Tray Fool-Proof Structure for NVMe Card Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Server equipment often suffers from costly damage due to incorrect insertion of NVMe cards into mismatched slots, leading to high maintenance costs.
Innovation Solution
A fool-proof structure is implemented in server equipment, featuring a casing with a fool-proof device and tray system that includes engagement members of different heights to prevent incorrect insertion, ensuring the connection card is either inserted or kept at a safe distance from the slot, thereby protecting it from damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If NVMe cards are used in server equipment, then storage performance and read/write speed are improved, but the risk of incorrect insertion and card damage increases
Solution Approach 1:
The patent applies asymmetry by providing engagement members at different heights (first height and second height) corresponding to different card sizes. This asymmetric height configuration ensures that each card size can only be inserted into the matching slot height, preventing incorrect insertion while maintaining high storage performance
Solution Approach 2:
The protection housing serves as an intermediary component between the NVMe card and the insertion slot. It includes engagement structures that interact with the engagement members to guide proper insertion and prevent mismatched cards from being inserted, thereby protecting against damage
2Reliability
If engagement members are added to prevent wrong insertion, then card protection is improved, but device complexity increases
Solution Approach 1:
The patent segments the protection function into separate components: the protection housing and the fool-proof device with engagement members. This segmentation allows the complex protection mechanism to be independently designed and replaced without affecting the entire server system, reducing overall system complexity while maintaining reliable card protection
3Reliability
If wrong insertion is prevented, then connection card damage is reduced, but maintenance cost increases due to additional components
Solution Approach 1:
The patent applies this principle by making the protection housing and fool-proof device as replaceable components. If these protective components are damaged during incorrect insertion attempts, they can be easily replaced without replacing the expensive NVMe card itself, thereby reducing maintenance costs while maintaining damage prevention

AI summary
Server equipment having a fool-proof structure includes a casing and a tray. The casing includes a storage unit area, a plurality of motherboard areas, a back plate, insertion slots and a fool-proof device. The fool-proof device selectively has an engagement member at a first height or an engagement member at a second height. The tray includes a motherboard, a connection card and a protection housing. When the protection housing is in contact with the engagement member at the first height, the connection card is correspondingly inserted into the insertion slot. When the protection housing is in contact with the engagement member at the second height, the connection card is spaced from the insertion slot by a distance. Accordingly, the connection card is prevented from being inserted to a wrong insertion slot, so damage to the connection card is avoided.
