Connector Ejection Mechanism with Resilient Member
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices with fixed input/output connectors on their outer shells compromise the aesthetic appearance and require complex mechanisms for connector ejection, which can be cumbersome and damaging.
Innovation Solution
An automatic ejection mechanism featuring a resilient member, fastening assembly, and limiting grooves within the outer shell allows for the sliding and controlled ejection of connectors, maintaining a clean exterior design and ensuring safe operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If connectors are fixed on the outer shell, then connection stability is improved, but aesthetic appearance deteriorates due to visible connectors
Solution Approach 1:
The connector system is segmented into two states: retracted (hidden within the outer shell) and extended (visible for connection). The outer shell itself is segmented with limiting grooves that guide the connector's movement paths, allowing the connector to be hidden when not in use while remaining accessible when needed.
Solution Approach 2:
The connector transitions from a static fixed position to a dynamic movable position. The resilient member enables the connector to automatically extend when force is applied and retract when the force is released, creating a dynamic system that adapts between hidden and visible states based on operational needs.
2Ease of operation
If complex ejection mechanisms are used, then connector ejection functionality is improved, but device complexity increases
Solution Approach 1:
The resilient member provides self-service by automatically propelling the connector outward when the fastening assembly releases it. No additional motors, actuators, or complex control systems are needed - the resilient member stores energy during insertion and automatically releases it during ejection, making the system self-actuating.
Solution Approach 2:
The fastening assembly acts as an intermediary between the user's manual input and the connector ejection process. It provides a controlled interface that, when actuated, releases the connector while the resilient member handles the actual ejection force, simplifying the overall mechanism while maintaining controlled operation.
3Device complexity
If connectors are manually ejected, then device complexity is reduced, but risk of damage to internal components increases
Solution Approach 1:
The resilient member serves as a protective intermediary that mediates between the connector and the internal components. It provides a controlled, gradual ejection force rather than sudden manual extraction, preventing damage to internal components while still enabling simple operation without complex mechanisms.
Solution Approach 2:
The resilient member is pre-compressed during connector insertion, storing elastic potential energy. This beforehand energy storage allows for a controlled release during ejection, cushioning the transition and preventing sudden movements that could damage internal components, while still requiring minimal operational complexity.

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 enables simple, safe, and reliable automatic ejection and retraction of connectors, preserving the outer shell's appearance and preventing damage to internal components.
Implementation Method 1
a force of the resilient member is applied on the connector to drive the connector to slide out of an opening of a front end of the accommodating space

AI summary
An automatic ejection mechanism of a connecting device includes an outer shell defining an accommodating space and including a rear cover covering a rear end of the accommodating space, a connector slidably received within the accommodating space, a fastening assembly located between the connector and the rear cover, and a resilient member located between the connector and the rear cover. The resilient member drives the connector to slide toward an opening of a front end of the accommodating space. The connector is received within the accommodating space by being fastened to the connector. The connector is ejected out of the opening of the front end by releasing the fastener from the connector.
