Solution Overview
Problem
Existing automated household devices, such as automatic dust collectors and mowers, require multiple devices for different tasks, leading to high costs, complexity, and inefficiencies due to separate charging stations and potential interference, with users needing to manually manage lawn watering and fertilization.
Innovation Solution
A modular self-moving robot system with interchangeable working modules, including a self-moving module and various working modules like mowers, sweepers, and fertilizers, that can automatically connect and disconnect, share energy, and switch between modes based on terrain recognition, allowing for multiple functions in a single device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple separate automated devices are disposed for different household tasks, then each device can perform its specific function reliably, but the total cost increases, the household environment becomes disordered, and multiple charging stations and wires are required
Solution Approach 1:
The patent applies universality by designing a single robot body that can interchangeably mount multiple working modules (dust collection module, lawn care module, snow removal module, etc.). The standardized interface units allow the same robot platform to perform different functions by simply changing modules, eliminating the need for multiple separate devices and reducing system complexity while maintaining functional reliability.
Solution Approach 2:
The patent segments the automated household system into a reusable robot body and interchangeable working modules. This segmentation allows each module to be independently designed, maintained, and replaced, while the common robot body provides shared resources (battery, control unit, sensors), reducing overall system complexity and cost.
2Device complexity
If an integrated automatic working device is designed to combine multiple functions, then device complexity is reduced, but the machine size becomes huge, weight increases, energy consumption increases, and working time after charging decreases
Solution Approach 1:
The patent divides the integrated system into a lightweight robot body and separate working modules. Each module contains only the necessary components for its specific function, avoiding the need to carry all possible functions simultaneously. The robot body weight remains constant and optimized, while modules are added only when needed, preventing weight and energy consumption increases.
Solution Approach 2:
The system dynamically adapts its configuration by mounting or disconnecting specific working modules based on current task requirements. This dynamic reconfigurability allows the robot to optimize its weight and energy consumption for each specific task, rather than carrying the burden of all possible functions at once.
3Adaptability or versatility
If an integrated automatic working device combines multiple functions, then versatility is improved, but manufacturing difficulty increases, fault rate increases, and maintenance cost increases
Solution Approach 1:
The patent segments the system into a standardized robot body and independent working modules with standardized interfaces. This segmentation allows each module to be manufactured separately by different suppliers using specialized processes, reducing overall manufacturing difficulty. The standardized interfaces ensure compatibility while allowing independent optimization of each component.
Solution Approach 2:
The standardized interface units enable a single robot body design to support multiple working modules, achieving functional versatility without increasing the complexity of the common components. Each module is designed independently for its specific function, simplifying the manufacturing of individual components while maintaining overall system versatility.
4Adaptability or versatility
If an integrated automatic working device combines multiple functions, then functional versatility is improved, but the machine cost increases and product popularization is affected
Solution Approach 1:
The patent achieves functional versatility through a universal robot body platform with standardized interface units that can accommodate multiple working modules. The common components (robot body, control unit, battery, sensors) are designed once and reused across all module configurations, spreading the design complexity over multiple sales rather than concentrating it in a single complex integrated device.
Solution Approach 2:
By segmenting the system into reusable robot body and interchangeable modules, the patent allows customers to purchase only the robot body once and then add specific modules as needed. This segmentation reduces the upfront cost and design complexity for each individual function while maintaining overall versatility, making the product more accessible and easier to popularize.
