Solution Overview
Problem
Conventional home robots are limited in their ability to perform multiple functions and adapt to user needs, as they are typically fixed to specific tasks and lack the capability to navigate obstacles effectively.
Innovation Solution
A robot design featuring a modular structure with a replaceable upper functional module, allowing users to change services by swapping modules, and incorporating a leg unit and wheel unit for enhanced mobility and obstacle navigation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional home robots are designed to perform specific functions, then they can reliably execute those functions, but they cannot provide various services according to different user needs
Solution Approach 1:
The robot system is divided into a base unit and detachable functional modules. The base unit contains common components (motor, battery, wheel unit), while specific functions are implemented in separate modules (cleaning module, entertainment module, transport module). Users can attach only the modules they need, achieving service variety without increasing overall system complexity.
Solution Approach 2:
The base unit is designed with universal interfaces and common components that can support multiple different functional modules. The motor, battery, and control system serve all modules, allowing the same base unit to perform various services by simply changing the attached module.
2Ease of operation
If two-wheeled robots are designed with small wheels for easy storage and maneuverability, then they occupy small space and have small rotation radius, but they cannot pass obstacles effectively and may fall over due to impact
Solution Approach 1:
The robot employs dynamic wheel mechanisms that can adjust their characteristics. The wheels can deform or change their effective diameter when encountering obstacles, allowing the robot to maintain both small size for maneuverability and sufficient obstacle-coping capability when needed.
Solution Approach 2:
The wheel parameters (such as diameter, material hardness, or inflation pressure) can be changed based on the terrain conditions. For normal operation, the wheels maintain small dimensions for easy storage and turning. When obstacles are detected, the wheel parameters are adjusted to improve obstacle-passing capability and reduce impact effects.

AI summary
A robot including an upper functional module that may be replaced and may provide services to users and add or change the services provided to the users by allowing the users to replace the upper functional module. The various services can include providing emotional stability by communicating with the user, transporting objects, charging mobile phones, and providing music and lighting suitable for mood, according to the user's needs.
