Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transmission systems face difficulties in assembly and maintenance due to the separate and disparate positioning of components, leading to complex assembly planning and increased risk of incorrect assembly.
Innovation Solution
A transmission system with an integrated actuator unit that includes a housing with positioning and centering pins, allowing for error-free mounting and easy assembly and maintenance by treating the actuator unit as a self-contained component.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If components are provided separately or arranged in different positions, then each component can be optimized for its specific function, but assembly and disassembly become difficult and complex
Solution Approach 1:
The patent combines multiple transmission control components (actuating element, positioning pins, centering pins, and housing) into a single integrated actuator unit. This merging allows the unit to be pre-assembled and tested as one module, improving functional reliability while simplifying final assembly into the transmission housing.
Solution Approach 2:
The actuator unit is designed as a separate, self-contained module that can be assembled and tested independently before integration into the transmission. This segmentation enables optimized functional design within the module while simplifying overall assembly procedures through modular installation.
2Ease of operation
If components are arranged in different positions, then each component can be accessed independently, but assembly planning becomes complex and time-consuming
Solution Approach 1:
By merging multiple components into one actuator unit with standardized positioning features, the patent reduces the number of separate assembly decisions required. The unit arrives pre-configured with all components in their correct positions, eliminating complex assembly planning while maintaining accessibility through the integrated design.
3Adaptability or versatility
If components are provided separately, then flexibility in design is maintained, but the risk of incorrect assembly increases
Solution Approach 1:
The positioning pins and centering pins act as intermediary elements that guide the actuator unit into its correct position within the transmission housing. These features serve as mechanical mediators that prevent incorrect assembly by providing physical constraints that only allow proper alignment, thereby eliminating assembly errors while maintaining design flexibility.
4Manufacturing precision
If the actuator unit is integrated with positioning and centering pins, then assembly error is prevented, but the device complexity increases
Solution Approach 1:
The positioning pins and centering pins are integrated as part of the actuator unit housing rather than being separate components. This merging reduces the overall component count and simplifies assembly, as the positioning features are already built into the unit during manufacturing, eliminating the need for separate installation steps.
