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 inefficiency, with each device needing separate charging stations and potential interference between systems, and users must manually perform tasks like watering and fertilizing lawns.
Innovation Solution
A modular self-moving robot that integrates mowing and cleaning functions, equipped with a ground recognizing unit to switch between modes based on terrain, and interchangeable modules for various tasks, including automatic liquid sprinkling, allowing a single device to perform multiple functions efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If multiple separate automated devices are used for different household tasks, then each device can be specialized and simple to manufacture, but the total cost increases, the household environment becomes disordered, and multiple charging stations and wires are required
Solution Approach 1:
The patent applies multi-functionality by designing a single robot device that can perform multiple household tasks including mowing, dust collection, and security protection. The robot achieves versatility through interchangeable working modules that can be attached and detached based on different task requirements, eliminating the need for multiple separate specialized devices.
Solution Approach 2:
The patent applies segmentation by dividing the robot into a base unit and separate interchangeable working modules. Each module is designed as an independent component that can be easily attached or detached from the base robot, allowing the system to be configured for different functions while maintaining manufacturing simplicity for each individual component.
2Adaptability or versatility
If an integrated automatic working device combining multiple functions is designed, then device versatility is improved, but the machine becomes difficult to design and manufacture, fault rate increases, and maintenance cost rises
Solution Approach 1:
The patent divides the integrated system into a base robot unit and separate functional modules. Each module is independently manufactured and tested, reducing overall manufacturing complexity and fault rates compared to a fully integrated design. The modular structure allows for easier maintenance and replacement of individual components.
Solution Approach 2:
The patent implements a dynamic configuration system where the robot can change its functional composition by attaching or detaching different working modules based on task requirements. This dynamic adaptability allows the system to maintain versatility while keeping the base unit relatively simple and easy to manufacture.
3Adaptability or versatility
If an integrated automatic working device combining multiple functions is designed, then functional versatility is improved, but machine size becomes huge and weight increases, causing increased energy consumption and reduced working time
Solution Approach 1:
The patent segments the functional components into separate modules that are only attached when needed. This prevents the robot from carrying unnecessary weight and energy consumption requirements for functions that are not currently being used, while still maintaining the capability to perform multiple different tasks by swapping modules.
Solution Approach 2:
The dynamic module swapping capability allows the robot to optimize its energy consumption by configuring itself with only the necessary working modules for each specific task. This dynamic adaptation prevents the energy waste associated with carrying and operating unnecessary functions, while preserving full functional versatility across different task scenarios.
4Adaptability or versatility
If an integrated automatic working device combining multiple functions is designed, then functional versatility is improved, but users may need to pay for functions which are not required actually
Solution Approach 1:
The patent segments the functional capabilities into separate purchasable modules. Users can acquire the base robot unit and then selectively add only the working modules they need for their specific tasks, rather than paying for an all-inclusive integrated system with functions they may never use. This modular acquisition model improves operational flexibility and cost-effectiveness.
