Pivot Shaft Transmission Device Assembly Simplification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pivot shaft transmission devices in electronic apparatuses are complex to assemble, affect the visual design, and are prone to dust accumulation, making them difficult to manufacture and maintain, especially in lightweight and thin designs.
Innovation Solution
A dual-shaft mechanism with a drive section, driver, and transmission unit, including a link unit and elastic body, allows for synchronized rotation and easy assembly, eliminating the need for notches and complex connections, while the elastic body provides a safety mechanism against external forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a conventional transmission device uses a case with a notch and complex connection components (claw section, restriction plate), then the transmission function is achieved, but the device complexity increases and assembly becomes difficult and troublesome
Solution Approach 1:
The patent merges the transmission support function directly into the rotary shaft by forming a protrusion on the rotary shaft that engages with a groove on the transmission support. This integration eliminates the need for separate connection components such as claw sections and restriction plates, thereby reducing device complexity and simplifying assembly while maintaining the transmission function.
Solution Approach 2:
The patent extracts and eliminates unnecessary components from the conventional transmission device. Specifically, it removes the case with notch, claw section, and restriction plate by redesigning the transmission mechanism to use a simplified rotary shaft-protrusion and transmission support-groove engagement system, thus reducing structural complexity.
2Shape
If a conventional transmission device uses a case with a notch for transmission support movement, then the transmission function is achieved, but the appearance and visual design are affected and dust accumulation occurs
Solution Approach 1:
The patent removes the case with notch from the transmission device design. Instead, the transmission support moves along the side surface of the rotary shaft through a groove-protrusion engagement mechanism. This elimination of the enclosed case structure prevents dust accumulation while maintaining the transmission function and improving appearance quality.
Solution Approach 2:
Rather than enclosing the transmission mechanism in a case with a notch (conventional approach), the patent inverts the design by exposing the transmission support movement along the rotary shaft side surface. This reversal eliminates the dust-trapping enclosure while achieving the same transmission effect and improving visual appearance.

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 redesigned pivot shaft transmission device simplifies assembly, maintains a clean and aesthetically pleasing design, and enhances the structural integrity by preventing dust accumulation and damage from external forces, while supporting the operation of electronic apparatuses in various modes.
Implementation Method 1
at least one elastic body assembled with each other... the elastic body provides an elastic move range between the first and second sections
Implementation Method 2
The rotary shaft has an eccentric section B1, which is eccentrically rotatable with the rotation of the rotary shaft... the eccentric section B1 of the rotary shaft pushes the transmission support B2 to make the connection section B3 and the carrier body B4 (longitudinally) move

AI summary
A pivot shaft transmission device provides a security system and is easy to assemble. The pivot shaft transmission device includes at least one rotary shaft, a drive section movable with the rotation of the rotary shaft, a driver (transversely) movable along a rail between a first position and a second position, a turning unit having a first end connected with the driver and a second end, and a transmission unit assembled with the second end of the turning unit. The transmission unit includes a first section, a second section and at least one elastic body assembled with each other. When the turning unit is swung, the transmission unit is driven to (longitudinally) move to drive a connection section and a carrier body for lifting or lowering a substrate body or a frame in accordance with the operation mode of an electronic apparatus.
