Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motive power transmission devices and electric power devices are prone to excessive external force transmission, particularly during unexpected high-speed battery motion, which can lead to connector or charging plug damage.
Innovation Solution
A motive power transmission device comprising a first member, a second member, and a third member, with elastic members and a buffer member strategically positioned on different transmission paths to absorb and dissipate excessive external forces, thereby preventing damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If connectors and charging plugs are directly connected without elastic members or buffer members, then the mechanical connection is simple and direct, but excessive external force during high-speed battery motion can damage the connectors or charging plugs
Solution Approach 1:
The patent applies beforehand cushioning by introducing elastic members (first elastic member on the first motive power transmission path, second elastic member on the second motive power transmission path) and a buffer member (on the third motive power transmission path between second and third members) that are pre-positioned to absorb excessive external forces before they can reach and damage the connectors or charging plugs during unexpected high-speed battery motion
Solution Approach 2:
The patent uses elastic members and buffer member as intermediary elements between the movable members (first, second, and third members) and the connectors/charging plugs. These intermediaries mechanically connect the members while absorbing shocks and preventing excessive force transmission to the vulnerable electrical connection components
2Reliability
If elastic members and buffer member are added to suppress excessive external force, then connector durability is improved, but the device structure becomes more complex with multiple members and components
Solution Approach 1:
The patent segments the motive power transmission system into distinct functional paths (first, second, and third motive power transmission paths) with dedicated elastic members and buffer members on each path. This segmentation allows each component to specialize in absorbing specific types of external forces while maintaining overall system reliability without requiring a completely redundant structure

AI summary
Provided is a power transmission device with which it is possible to minimize transmission of an excessive external force. This power transmission device has an input lever, an output lever, and a housing that are capable of moving relative to each other and that are mechanically connected to each other so as to be capable of transmitting power therebetween. The power transmission device has: a main spring disposed on a first power transmission path that is for transmitting power between the input lever and the output lever; a return spring disposed on a second power transmission path that is for transmitting power between the input lever and the housing; and a damper disposed on a third power transmission path that is for transmitting power between the output lever and the housing.
