A latch mechanism comprising a frame, elastic sheet, sliding bracket, resilient restoring member, and hooking portion is introduced, featuring a grip portion and a hooking mechanism that simplifies the securing of the chassis to the server rack, reducing component complexity and material costs while enhancing user convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional stopping mechanism is installed in the server rack, then the server unit can be positioned and prevented from vibrating or derailing, but the structure becomes complex and difficult to operate
Solution Approach 1:
The latch mechanism is divided into separate functional components: a resilient member (spring) that provides restoring force, a latch member with protrusion that engages with the frame, and a grip portion for user operation. This segmentation allows each component to perform its specific function efficiently, reducing overall complexity while maintaining reliability
Solution Approach 2:
The resilient member automatically returns the latch member to its original position after being displaced, providing self-resetting functionality. This eliminates the need for complex resetting mechanisms and reduces operational complexity while ensuring the server unit remains securely positioned
2Reliability
If a traditional stopping mechanism is used, then the server unit can be secured in position, but the assembly and operation become inconvenient and time-consuming
Solution Approach 1:
The resilient member automatically returns the latch member to its engaged position with the frame after being displaced during insertion or removal. This self-resetting action ensures secure positioning without requiring manual intervention for resetting, significantly improving operational convenience while maintaining reliable securing
Solution Approach 2:
Instead of requiring the user to actively engage a complex locking mechanism, the design allows the latch member to passively engage with the frame through the restoring force of the resilient member. The user simply needs to insert or remove the server unit, and the latch mechanism automatically secures or releases it, inverting the traditional active-locking approach
3Manufacturing precision
If traditional stopping mechanisms are designed with complex structures, then positioning accuracy is improved, but material costs and structural complexity increase
Solution Approach 1:
The positioning function is achieved through simple geometric features rather than complex mechanisms: a protrusion on the latch member engages with a corresponding feature on the frame, and the resilient member provides positional feedback. This segmented approach achieves precise positioning through simple, manufacturable components
Solution Approach 2:
The resilient member's elastic properties enable it to deform during insertion/removal and automatically return to its original position, providing precise positioning through material property rather than complex mechanical geometry. This changes the approach from geometric complexity to material property utilization

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 latch mechanism allows for easy and secure mechanical locking of the chassis to the server rack through simple operations, reducing structural complexity and material costs while improving user convenience and safety by utilizing a resilient restoring force for automatic re-engagement.
Implementation Method 1
deform the resilient restoring member so as to store a restoring force capable of returning the protruding portion back to the receiving portion
Implementation Method 2
The elastic sheet is disposed in the accommodation space, and attached to an inner surface of the frame

AI summary
A latch mechanism includes a frame, an elastic sheet, a sliding bracket, a hooking portion, and a resilient restoring member connected to the frame and the sliding bracket. The elastic sheet includes a fixing portion, a receiving portion and a fastening member. The fixing portion is fixed to the frame being opposite to the fastening member. The sliding bracket includes a bracket body slidably disposed between the elastic sheet and the frame, and a protruding portion received in the receiving portion. The hooking portion is connected to the bracket body, and removably hooked on a fastener portion. When the sliding bracket moves the protruding portion, the resilient restoring member and the hooking portion, the protruding portion pushes the fastening member into the frame, and the hooking portion is hooked by the fastener portion to keep the resilient restoring member not being resumed.
