Solution Overview
Problem
The challenge in managing and positioning sliding modules on 1U server racks is ensuring secure and stable operation, particularly under height constraints, to prevent dislodgment by external forces or vibrations, while maintaining efficient space utilization and user safety.
Innovation Solution
A sliding module positioning device comprising a base, positioning pin, elastic device, internal pushing member, and external control member, which securely locks the positioning pin into a predetermined position on the server rack, using a retracting bracket and elastic piece to maintain stability and prevent protrusion, allowing safe operation and retraction of sliding modules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If sliding modules are installed on 1U server rack, then space utilization is improved, but the modules may be dislodged by external forces or vibrations
Solution Approach 1:
The positioning pin is pre-configured to automatically engage with the positioning hole when the sliding module is inserted into the server rack, establishing secure positioning before any external forces or vibrations can occur. This preliminary engagement ensures reliability is established in advance rather than reacting to dislodgment risks.
Solution Approach 2:
The positioning pin acts as an intermediary element between the sliding module and the server rack structure. It mediates the connection by transferring and stabilizing the module's position, preventing direct dislodgment from external forces while maintaining the space-efficient 1U configuration.
2Reliability
If positioning mechanism is added to sliding module, then operational safety is improved, but device complexity increases
Solution Approach 1:
The positioning pin and positioning hole form a self-service mechanism where the pin automatically engages with the hole through the natural insertion motion of the sliding module. The elastic piece provides self-adjusting force to maintain engagement without requiring external control systems, buttons, or complex actuation mechanisms, thereby improving operational safety while minimizing added complexity.
Solution Approach 2:
The positioning function is extracted as a separate, simple mechanical feature (the positioning pin) that can be independently implemented without complicating the overall sliding module design. This extracted positioning mechanism handles safety requirements independently, allowing the rest of the module to remain simple and focused on its primary sliding function.

Function Achieved in This Case
The solution provides a safe and stable positioning system for sliding modules on server racks, enhancing operational safety and space utilization by securely fixing the modules at predetermined positions, allowing for reliable operation and easy retrieval, while preventing damage from external forces or vibrations.
Implementation Method 1
The elastic device is coupled to the positioning pin to push the positioning pin into a positioning hole in a predetermined direction
Implementation Method 2
The elastic piece can move the external control member to allow the positioning pin to protrude from the external control member and couple to the positioning hole

AI summary
A sliding module positioning device for locking a sliding module at a predetermined position on a rack is described. The sliding module positioning device includes a base, a positioning pin, an elastic device, an internal pushing member, and an external control member. The positioning pin is moveable on the base and coupled to the elastic device for pushing the positioning pin into a positioning hole on a positioning bracket. The internal pushing member can push the positioning pin away from the positioning hole. The external control member connects with the internal pushing member, and the positioning pin couples to an inner surface of the internal pushing member to prevent the positioning pin protruding from the external control member after the positioning pin is moved away from the positioning hole. The positioning device further utilizes an elastic piece for coupling the positioning pin to the positioning hole.
