Solution Overview
Problem
Existing bistable relay systems face challenges in manually resetting and testing, as they require a mechanical connection that interferes with electrical signal control during switching states, affecting resilience and usability.
Innovation Solution
A mechanical operating assembly for a bistable relay featuring an actuating mechanism with a movable actuating member and transmitting members, including inclined surfaces and springs, allows for state switching without hindering electrical signal control, enabling manual reset and visual indication of relay states through a housing window.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a mechanical connection is added to enable manual resetting and testing, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The mechanical operating assembly is nested within the relay housing, with the actuating mechanism and transmitting members integrated into the existing relay structure. The reset button and test button are housed within the housing, and their actuating members are nested among the relay components, allowing manual operation without adding external mechanical connections.
Solution Approach 2:
Transmitting members serve as intermediaries between the actuating members (reset button and test button) and the bistable relay components. These transmitting members transfer the mechanical action from the buttons to the relay's paddle and other components, enabling manual control without direct mechanical connection to the relay's electrical contacts.
2Ease of operation
If transmitting members with inclined surfaces are used, then ease of operation is improved, but manufacturing precision requirements increase
Solution Approach 1:
The transmitting members are designed with inclined surfaces that convert the vertical pressing motion of the buttons into horizontal or rotational motion of the relay components. The inclined surfaces provide a gradual transition of force, making the actuation smoother and reducing the impact on manufacturing precision requirements by distributing the contact over a surface area rather than a point.

Function Achieved in This Case
Enables reliable manual control of bistable relay states without interfering with electrical signal control, improving resilience and usability by allowing free tripping and visual confirmation of state changes.
Implementation Method 1
a first reset spring (14) installed between the actuating member and the bracket, for returning the actuating member from the actuating position to the initial position... a second reset spring (17) installed between the second transmitting member and the bracket
Implementation Method 2
The actuating member (12) has a first inclined surface (121), and the first transmitting member (13) has a second inclined surface (131) corresponding to the first inclined surface. When the actuating member moves downward, the first inclined surface (121) abuts the second inclined surface (131), causing the first transmitting member to move to the right
