Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional reduction gears lack input/output position feedback, making it difficult to change the input method after manufacturing, limiting control over power transmission, and increasing complexity, maintenance, and volume, which hinders miniaturization and adaptability to various driving units.
Innovation Solution
A multi-input reduction gear with detachable input/output position feedback units, including an output feedback unit embedded in the reduction gear body to detect the output position, an input mediating unit connected to a power source shaft, and an input feedback unit stacked between the reduction gear body and input mediating unit to detect the input position, allowing for selective adoption of mechanical components and precise control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If an output position feedback unit is installed outside the reduction gear by a power transmit unit, then position feedback can be achieved, but the device structure becomes complex and volume increases
Solution Approach 1:
The patent merges the output position feedback unit with the reduction gear body by integrating it into the output unit. The feedback unit is positioned within the reduction gear structure itself, eliminating the need for separate external installation and power transmit units, thereby reducing structural complexity while maintaining feedback functionality
Solution Approach 2:
The reduction gear body is designed to serve multiple functions: it provides mechanical power transmission and simultaneously houses the output position feedback unit. The output unit structure is configured to detect output position while also transmitting mechanical power, achieving multi-functionality and reducing overall device complexity
2Ease of manufacture
If a conventional reduction gear with fixed input method is used, then manufacturing is simplified, but adaptability to various driving units is limited
Solution Approach 1:
The input unit is designed with a detachable coupling structure that allows dynamic reconfiguration. The input mediating unit can be connected or disconnected from the input unit through a coupling mechanism, enabling the reduction gear to adapt to different driving units (motors, engines, etc.) while maintaining a simple fixed manufacturing process for the core reduction gear body
Solution Approach 2:
The input mechanism is segmented into separate detachable components: the input unit, input mediating unit, and coupling structure. This segmentation allows the core reduction gear to be manufactured with a fixed simple structure, while adaptability is achieved through interchangeable modular input components that can be attached as needed
3Ease of manufacture
If power transmission control is not integrated into the reduction gear, then manufacturing cost is reduced, but control over power transmission and input/output displacement cannot be achieved
Solution Approach 1:
The control functionality is merged into the reduction gear structure by integrating position detection capabilities into both the input unit and output unit. The input feedback unit detects input displacement and the output feedback unit detects output position, with both units embedded within the reduction gear body, enabling automated control without adding external complex systems
Solution Approach 2:
The patent implements feedback mechanisms by incorporating input and output feedback units that detect and provide information about input displacement and output position. This feedback enables automated control of power transmission while keeping the overall structure integrated within the reduction gear, avoiding the need for separate external control systems that would increase manufacturing cost
4Adaptability or versatility
If the reduction gear structure is made complex to support multiple input methods, then adaptability improves, but maintenance cost and volume increase
Solution Approach 1:
The reduction gear is segmented into a fixed core structure (reduction gear body with gear mechanism) and detachable input components (input unit, input mediating unit). This segmentation allows adaptability through interchangeable input components while keeping the main reduction gear structure simple and unchanged, reducing maintenance complexity and volume
Solution Approach 2:
The reduction gear body is designed with universal interfaces and a standardized coupling structure that can accommodate different types of input driving units. The input unit and input mediating unit serve multiple functions: they can be connected or disconnected, and the coupling structure supports various connection types, providing versatility without requiring complex internal modifications to the reduction gear body
