Replaceable Timer Movement Module With Inserting Pins
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional timer modules have a fixed timing movement that is prone to damage, leading to high maintenance costs and resource wastage, as the entire module is often replaced when the movement is damaged, and the timing function cannot be changed once determined.
Innovation Solution
A novel timer module design where the timer movement is not directly welded to the circuit board, featuring a replaceable movement with inserting pins that connect to a master control circuit board, allowing for different timing functions and reducing maintenance costs by enabling the replacement of the movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the timer movement is fixedly welded on the circuit board, then the timing function is stable and reliable, but the maintenance cost is high and the entire module must be replaced when the movement is damaged
Solution Approach 1:
The timer module is divided into two independent parts: a reusable master control circuit board and a replaceable movement. The movement is no longer welded to the circuit board but is instead connected via inserting pins that plug into inserting slots on the circuit board. This segmentation allows the movement to be replaced independently when damaged, while the master control circuit board can be reused, thereby reducing maintenance costs and avoiding waste of resources.
2Stability of the object's composition
If the timer movement is fixedly welded on the circuit board, then the timing function is determined and stable, but the timing function cannot be changed once determined
Solution Approach 1:
The timer module transitions from a static, fixed configuration to a dynamic, interchangeable configuration. The movement can be removed and replaced with different types of movements through the inserting pin and slot connection mechanism. This allows the timing function to be changed according to different application requirements while maintaining stable operation during use, thus achieving both stability and flexibility.
3Device complexity
If the timer movement is fixedly welded on the circuit board, then the structure is simple and compact, but the resource waste is high when the movement is damaged
Solution Approach 1:
By segmenting the timer module into a reusable master control circuit board and a replaceable movement, the design avoids the need to replace the entire module when the movement is damaged. Only the movement portion needs to be replaced, significantly reducing resource waste. The inserting pin and slot connection maintains structural simplicity while enabling this selective replacement capability.

AI summary
Disclosed is a novel timer module. The novel timer module includes a replaceable movement, a master control circuit board, an upper housing, and a lower housing. A circuit board is disposed inside the replaceable movement. Five first inserting pins are welded on the circuit board. The first inserting pins are exposed from the outside of a housing of the replaceable movement. The master control circuit board is located in the upper housing and the lower housing, and is fixed on an upper surface of the lower housing. A relay is disposed inside the master control circuit board. Contacts of the relay respectively extend and are fixed on a surface of the master control circuit board by using leads. Therefore, a problem that a conventional timer movement is fixedly welded on a circuit of a timer module can be resolved.
