Power Distribution Module Handle and Elastic Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing power distribution modules in servers face issues with easy plugging and removal due to excessive friction between connectors, leading to unstable connections.
Innovation Solution
The power distribution module incorporates a handle and first elastic members connected between frames and the device body, allowing the main body to be firmly secured through elastic force, preventing loose connections and facilitating stable operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the power distribution module uses traditional connector friction for securing, then the connection may be simple in structure, but the friction is too large making plugging and removal difficult and the connection is not tight enough leading to easy connection failure
Solution Approach 1:
The patent applies dynamics by using an elastic member that can dynamically adjust its state between compressed and relaxed. When the handle is moved to the locking position, the elastic member compresses to provide strong securing force; when moved to the release position, the elastic member relaxes to allow easy removal. This dynamic behavior resolves the contradiction between secure connection and easy operation.
Solution Approach 2:
The patent implements periodic action through the cyclic movement of the handle between locking and release positions. The elastic member periodically compresses and relaxes corresponding to the handle's movement cycles, enabling repeated secure connection and release operations. This periodic action allows the system to alternate between high securing force and easy removal states.
2Reliability
If the connector friction is increased to prevent connection failure, then the connection stability improves, but the force required to plug in or remove the module increases significantly
Solution Approach 1:
The elastic member provides dynamic force modulation. In the locked state, it exerts high force to ensure reliable connection. During removal, when the handle is moved to the release position, the elastic member's force is reduced or redirected, allowing the connector to be pulled out with minimal force. This dynamic force adjustment resolves the contradiction between high connection reliability and low removal force.
Solution Approach 2:
The elastic member acts as an intermediary between the handle and the connector. It translates the handle's movement into controlled securing or releasing actions. By mediating the force transmission, it ensures high force is applied only when needed for secure connection, while allowing easy force application for removal, thus resolving the force contradiction.
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 ensures the power distribution module is securely plugged into the device body, preventing connection failures and ensuring stable power supply by utilizing elastic forces to maintain the main body's position, thus enhancing operational reliability.
Implementation Method 1
The at least one first elastic member is connected between the device body and the at least one first frame. The at least one first frame blocks the handle by an elastic force of the at least one first elastic member, so that the main body is limited on the device body.
Implementation Method 2
when the handle is rotated relative to the main body from a release position to a locking position, the handle resists the elastic force of the at least one first elastic member to drive the at least one first frame to slide relative to the device body.
