Server Power Supply Safety Mechanism with Spring Block
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional servers with removable power supplies pose a risk of electric shock during maintenance, upgrading, or transportation due to the power supply remaining active, which can injure users.
Innovation Solution
A server design incorporating a protecting component with pressed sheet springs and blocking sheet springs that are bent or flattened to prevent the power supply from being inserted when the lid is detached, ensuring the power supply is safely secured within the chassis only when the lid is properly closed, thereby preventing accidental electrical connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a removable power supply is provided for convenience of maintenance, upgrading and transporting, then the ease of operation and maintenance is improved, but the safety against electric shock deteriorates
Solution Approach 1:
The blocking sheet spring is pre-configured in a protruding position that automatically blocks the power supply insertion path when the lid is detached. This preliminary positioning ensures that before any electrical connection can occur, the mechanical block is already in place, preventing electric shock during maintenance operations.
Solution Approach 2:
The blocking sheet spring acts as an intermediary mechanical element between the lid position and the power supply insertion. When the lid is detached, the blocking sheet spring protrudes to intercept and prevent the power supply from being inserted, thereby mediating the interaction between the user and the electrical components.
2Ease of operation
If the power supply is made removable for transportation, then the ease of operation is improved, but the reliability of electrical connection safety deteriorates
Solution Approach 1:
The blocking sheet spring is pre-positioned to protrude into the accommodating space when the lid is detached, creating a mechanical barrier before any electrical connection can be established. This ensures that even during transportation or handling, the power supply cannot be accidentally connected to the motherboard.
Solution Approach 2:
The protecting component automatically activates based on the lid position without requiring external control systems. When the lid is detached, the blocking sheet spring self-activates to block insertion; when the lid is closed, the pressed sheet spring automatically flattens the blocking section to allow insertion. This self-regulating mechanism ensures reliable safety without additional complexity.
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
The solution effectively prevents electric shock by ensuring the power supply is not inadvertently connected to the motherboard when the lid is detached, enhancing user safety during server maintenance and handling.
Implementation Method 1
The pressed sheet spring and the first blocking sheet spring are bent or flattened simultaneously when the movable part being moved relative to the cover

AI summary
A server includes a chassis, a protecting component and at least one power supply. The chassis includes a case, a cover and a lid. The cover is disposed on the case to form at least one accommodating space, and the lid is detachably disposed on the case and covers the cover. The protecting component is assembled on the cover and includes a pressed sheet spring and a first blocking sheet spring. Both the pressed sheet spring and the first blocking sheet spring includes a bending section, and the bending sections are separated apart. The two sheet springs are fastened to the cover to form a fastening part, and the two sheet springs are connected to each other to form a movable part. The two sheet springs move simultaneously when the movable part is moved relative to the cover. The power supply is removably disposed in the accommodating space.
