Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric capstans require additional space and weight for separate water pumps and other functional devices, increasing cost and complexity when multiple functions are needed, such as traction and self-rescue operations in off-road vehicles and barges.
Innovation Solution
An electric capstan with an engagement-disengagement gear and functional module configuration, allowing for the integration and easy connection of external functional modules, such as water pumps, through accessible interfaces and a clutch mechanism, reducing the overall size and weight while enabling multiple functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate water pumps and functional devices are equipped for multiple functions, then functional versatility is improved, but device complexity and space occupation increase
Solution Approach 1:
The patent applies universality by designing the electric capstan with a standardized functional module interface that can accommodate different functional modules (water pump, air compressor, winch, etc.). The engagement-disengagement gear and connecting members create a universal mounting system where one base structure supports multiple functions through interchangeable modules, eliminating the need for separate dedicated mounting systems for each function.
Solution Approach 2:
The patent merges multiple functional devices into a single integrated electric capstan unit. By combining the motor, reduction gear, winching roller, and functional module interface into one consolidated structure, the patent reduces overall system complexity while maintaining multiple functions. The functional modules share common mounting structures, power sources, and control systems.
2Adaptability or versatility
If separate water pumps and functional devices are equipped for multiple functions, then functional versatility is improved, but space occupation inside vehicles or ships increases
Solution Approach 1:
The standardized functional module interface allows multiple functions to be consolidated into a single mounting space. Different functional modules (water pump, air compressor, winch) can be attached to the same electric capstan unit, significantly reducing the total space required compared to separate dedicated mounting locations for each function.
Solution Approach 2:
The functional modules are designed to be nested within or attached to the electric capstan structure. The modules can be positioned around the motor and gear assembly, utilizing the existing structural space rather than requiring additional external mounting areas. This nesting approach minimizes the overall footprint.
3Adaptability or versatility
If separate water pumps and functional devices are equipped for multiple functions, then functional versatility is improved, but weight increases
Solution Approach 1:
By merging multiple functional devices into a single integrated electric capstan unit, the patent eliminates redundant structural components, mounting hardware, and separate power transmission systems. The shared motor, reduction gear, and control systems reduce overall weight compared to having separate complete systems for each function.
Solution Approach 2:
The universal functional module interface allows lightweight modular attachments rather than requiring heavy integrated systems. Each functional module can be optimized independently for its specific function while sharing the common heavy components (motor, gear case), reducing total system weight.
4Adaptability or versatility
If separate water pumps and functional devices are equipped for multiple functions, then functional versatility is improved, but cost increases
Solution Approach 1:
The integrated electric capstan design consolidates multiple functions into a single manufacturable unit, enabling economies of scale in production. The shared components (motor, reduction gear, housing, control electronics) can be manufactured once and configured for different functions, reducing per-unit costs compared to producing separate complete systems for each function.
Solution Approach 2:
The standardized functional module interface creates a platform product that can be produced in large volumes with different functional attachments. This modularity allows for standardized manufacturing processes, reduced inventory requirements, and easier maintenance, all of which reduce overall system cost.
