Plug Locking Mechanism with Impact-Responsive Unlatching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic apparatuses with plugs are prone to damage when the plug, in an extended state, is impacted by a force in the direction of retraction, as the locking mechanism fixes the plug's position, concentrating and amplifying the impact force.
Innovation Solution
A locking mechanism that automatically becomes ineffective upon impact in the direction of plug retraction, allowing the plug to slide back into the housing, thereby absorbing and distributing the impact force and preventing damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the locking structure locks the plug when it extends out of the port, then the plug position is fixed and stable, but the plug is easily damaged when impacted by a force in the retraction direction
Solution Approach 1:
The locking mechanism transitions from a static locked state to a dynamic unlocked state upon detecting impact force. The elastic component allows the locking structure to automatically disengage when subjected to impact in the retraction direction, converting the rigid locking system into an adaptive one that responds to external forces.
Solution Approach 2:
The elastic component pre-stores energy to provide cushioning protection. When impact occurs, the elastic component absorbs the impact energy through deformation, preventing the force from being directly transmitted to the plug and causing damage.
2Reliability
If the locking structure uses a stop slot and stop portion to fix the plug, then the plug remains stationary during use, but the concentrated impact force damages the plug
Solution Approach 1:
The system changes the state parameter of the locking mechanism from locked to unlocked based on the applied force. The elastic component detects the impact force and triggers a parameter change in the locking structure, causing it to transition from a force-transmitting state to a force-absorbing state.
Solution Approach 2:
The elastic component acts as an intermediary between the impact force and the locking structure. It mediates the interaction by absorbing the impact energy and controlling the unlocking process, preventing direct transmission of the concentrated force to the plug.
3Ease of operation
If the button and spring structure is used for locking, then the plug can be securely held, but the rigid structure transmits impact force directly to the plug
Solution Approach 1:
The spring-loaded button structure transitions from a rigid locking position to a flexible unlocking position upon impact. The spring allows the button to move dynamically in response to impact forces, enabling the locking mechanism to adapt to external conditions while maintaining ease of manual operation.
Solution Approach 2:
The spring component is pre-loaded to provide cushioning capacity. When impact occurs, the spring compresses or extends to absorb the impact energy, preventing direct transmission of the force to the plug while maintaining the operational functionality of the button control.
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 mechanism effectively buffers impact forces, reducing the risk of plug damage by allowing it to retract into the housing, thus protecting the plug from impact-induced damage.
Implementation Method 1
a spring 17 is fixedly disposed between the end and the support 16. An elastic force direction of the spring 17 extends in a direction towards the sliding slot
Implementation Method 2
the locking mechanism automatically becomes ineffective when the plug is impacted by a force in a direction in which the plug retracts into the port... allowing the plug to slide back into the housing, thereby absorbing and distributing the impact force
