Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In environments where interface standards cannot be visually distinguished, such as dark environments, connecting electronic devices for charging or communication is challenging due to the need for precise interface matching, leading to potential device failure or damage.
Innovation Solution
A plug design featuring stretchable and retractable conductive pins arranged between insulating pins, which automatically extend and retract to match the interface standards of different electronic devices, ensuring correct electrical contact and preventing false connections through a linkage mechanism and identification circuit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional fixed interface plugs are used, then the structure is simple and easy to manufacture, but the plug cannot adapt to different interface standards and may cause device damage in dark environments
Solution Approach 1:
The patent applies the dynamics principle by making the conductive pins stretchable and retractable along the axis direction. The conductive pin includes a needle portion and a step pillar that can extend outward or retract into the housing based on insertion detection, transforming a static plug structure into a dynamic one that adapts to different interface standards automatically
Solution Approach 2:
The patent implements preliminary action by pre-configuring multiple conductive pins with different intervals and arrangements within the housing. Before actual insertion, the system detects the interface type and pre-positions the appropriate conductive pins to extend, while others remain retracted, enabling the plug to be ready for the correct interface standard in advance
2Reliability
If multiple conductive pins with different arrangements are provided, then the plug can identify and adapt to different interface standards, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The patent applies segmentation by dividing the conductive pin structure into modular components: a housing, multiple independently controllable conductive pins, insulating pins, and a linkage mechanism. Each conductive pin can be independently positioned and controlled, allowing selective extension based on interface type detection, which simplifies the control logic while maintaining manufacturing feasibility
Solution Approach 2:
The patent introduces insulating pins as intermediary elements that interact with the interface structure during insertion. These insulating pins detect the presence and type of interface contacts, triggering the linkage mechanism to selectively extend or retract the conductive pins, thereby mediating between the physical interface and the electrical connection
3Ease of operation
If the conductive pin is made stretchable and retractable, then the plug can automatically adapt to different interface standards, but the device complexity and control mechanism requirements increase
Solution Approach 1:
The patent implements self-service through the linkage mechanism that automatically responds to insertion detection. When the plug is inserted into an interface, the insulating pins interact with the interface structure, automatically triggering the linkage mechanism to extend or retract the conductive pins without requiring external control signals or complex electronic circuits
Solution Approach 2:
The patent employs periodic action through the elastic components that provide restoring force to the conductive pins. The pins naturally tend to retract due to the elastic force, and extension occurs periodically only when triggered by interface detection, creating a rhythmic extend-retract behavior that simplifies control
