Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional signal transmission lines for portable electronic devices require additional space for switch structures, making them bulky and inconvenient for file transfer and battery recharge.
Innovation Solution
An elastically extendable signal transmission module with a data connector that can be extended and retracted via pressing, utilizing a linked unit with elastomers and a lock block to secure the connector, eliminating the need for a separate switch structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a separate switch structure is added to control the data connector, then the connector can be extended and retracted, but the device complexity and space requirements increase
Solution Approach 1:
The patent merges the switch function directly into the data connector by making the connector itself movable between extended and retracted positions. The connector body acts as both the signal transmission interface and the switching mechanism, eliminating the need for a separate switch structure. This is achieved through a sliding block mechanism that moves the connector between a first position (extended) and a second position (retracted), integrating control functionality into the connector itself.
2Ease of operation
If a separate switch structure is added to control the data connector, then the connector can be extended and retracted, but the device occupies more space
Solution Approach 1:
The switch function is merged into the data connector, using the connector's own movement between extended and retracted positions to control signal transmission. This integration eliminates the need for additional switch components and the space they would occupy, achieving both functionality and space efficiency.
Solution Approach 2:
The data connector is designed to be nested within the signal transmission module when in the retracted position. The connector can be stored inside the module body, and only extends outward when needed for connection. This nesting approach minimizes the device's footprint while maintaining full functionality when required.
3Area of stationary object
If the data connector is made extendable and retractable, then space is saved, but the mechanism becomes more complex
Solution Approach 1:
The mechanism achieves both space savings and controlled complexity by merging the switching function into the connector's movement mechanism. The sliding block that moves the connector between positions serves dual purposes: it controls the connector's extension/retraction and simultaneously controls the electrical connection state, eliminating the need for separate switching components and reducing overall device complexity.
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 module allows for direct and convenient extension and retraction of the data connector, saving space and enhancing usability by integrating the switch function into the connector mechanism, facilitating data transmission and battery recharge without additional bulk.
Implementation Method 1
The linked unit has a first shaft, a second shaft, a third shaft, a first elastomer and a second elastomer. The data connector rotates and expands according to the first shaft and the first elastomer
Implementation Method 2
The link includes a first end pivoting on the third shaft and a second end with a cam. During the retraction of the data connector, the cam of the link moves to the secure location along the incline plane of the track
Data Source
AI summary
A signal transmission module is provided. The signal transmission module includes an electrical connector, a linked unit, a data connector, a sliding block, a link and a lock block. The data connector rotates and expands according to a first shaft and a first elastomer of the linked unit, and electrically connects to the electrical connector. During retraction of the data connector, the data connector pushes the sliding block. Then the sliding block moves against the lock block so that the lock block rotates. The lock block rotates to lock and secure the data connector by the lock piece, while a cam of the link moves to a secure location along an incline plane of a track of the sliding block.
