Solution Overview
Problem
The relationship between the timing of the first movable member's operation in the first direction and the second movable member's operation in the second direction is not synchronized due to manufacturing errors or gaps in the drive mechanism, affecting the driving feeling.
Innovation Solution
A driving machine with an energizing mechanism for both movable members, and regulating mechanisms to control their operations, ensuring the second movable member's operation is synchronized with the first movable member's, using a third regulating mechanism that switches states to align their timing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a drive mechanism with multiple elements is used to operate the first and second movable members, then the driving machine can achieve the required function of operating both movable members, but manufacturing errors and gaps between elements cause timing mismatch between the movable members
Solution Approach 1:
The drive mechanism is divided into separate regulating mechanisms for the first and second movable members. The first regulating mechanism controls the first movable member independently, while the second regulating mechanism controls the second movable member independently. This segmentation allows each mechanism to be optimized and adjusted separately, compensating for manufacturing errors and timing mismatches that would affect a unified mechanism.
Solution Approach 2:
The regulating mechanisms are designed to preliminarily adjust the timing of each movable member before they operate together. By pre-adjusting the timing through the regulating mechanisms, the system compensates for manufacturing errors and gaps, ensuring synchronized operation of both movable members without requiring extremely high manufacturing precision.
2Ease of manufacture
If the drive mechanism elements are manufactured with standard tolerances, then manufacturing cost is reduced, but timing synchronization between movable members deteriorates
Solution Approach 1:
The regulating mechanisms act as intermediary devices between the drive mechanism elements and the movable members. These intermediaries provide adjustment capability that compensates for timing mismatches caused by standard tolerance manufacturing, allowing synchronization without requiring high-precision manufacturing of all components.
Solution Approach 2:
The regulating mechanisms introduce dynamic adjustment capability to the otherwise static drive mechanism. The ability to adjust timing parameters dynamically allows the system to compensate for manufacturing variations and maintain synchronization, transforming a rigid system into one that can adapt to manufacturing tolerances.

Function Achieved in This Case
This solution stabilizes the timing relationship between the two movable members, enhancing the driving feeling by ensuring precise coordination of their operations.
Implementation Method 1
The coil spring is compressed by operations of the plunger and the weight, and the coil spring stores (accumulates) elastic energy.
Implementation Method 2
When the roller cam of the first pulley is released from the plunger, the plunger starts operating downward due to elastic energy of the coil spring.
Implementation Method 3
When the roller cam of the second pulley is released from the weight, the weight starts operating upward due to the elastic energy of the coil spring.
