Robot Foot Supporter Dynamics for User Comfort
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing robots designed for daily life are limited in their ability to provide a range of services, leading to low cost-effective utilization, as they are typically specialized for specific tasks.
Innovation Solution
A robot with a foot supporter that can move forward and backward, equipped with a moving mechanism between the foot supporter and a lower plate, allowing it to adjust its position and accommodate different user needs, including a seat and arm supporters for enhanced versatility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the robot is designed for specific services only, then the service function is specialized, but the cost-effective utilization is low
Solution Approach 1:
The foot supporter is designed to move between a first position (retracted) and a second position (extended) using a moving mechanism. This dynamic configuration allows the robot to adapt its structure for different services - providing a compact form when not in use and an extended form when foot support is needed, thereby increasing versatility without permanently increasing structural complexity
Solution Approach 2:
The robot integrates multiple functions into a single platform: it can provide foot support, seat support, and arm support. The moving mechanism enables the foot supporter to serve multiple purposes - supporting user feet during operation and potentially serving as additional structural support. This multi-functionality increases adaptability while maintaining reasonable device complexity
2Ease of operation
If the foot supporter is fixed, then the structure is simple, but the user comfort is reduced
Solution Approach 1:
The foot supporter transitions from a fixed structure to a dynamic one that can move between first and second positions. This allows the foot supporter to adapt to different user needs and operational states, improving user comfort while the moving mechanism manages the added complexity in a controlled manner
Solution Approach 2:
The moving mechanism uses relatively simple components (motor, lead screw, moving body) that can be manufactured cost-effectively. These components provide the necessary functionality without requiring complex or expensive mechanisms, maintaining cost-effectiveness while enabling user comfort through movement
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The robot's ability to adjust its foot supporter and seat position enhances user comfort and versatility, allowing it to perform a variety of tasks, thereby increasing its utility and cost-effectiveness in daily life applications.
Implementation Method 1
a motor mounted on the lower plate; a lead screw disposed lengthily in a front-rear direction, the lead screw being connected to the motor

AI summary
Provided is a robot including a main body provided with a traveling wheel, a seat disposed above the main body, a foot supporter protruding forward from the main body, a lower plate disposed below the foot supporter, and a moving mechanism disposed between the lower plate and the foot supporter, the moving mechanism allowing the foot supporter to move forward and backward between a first position and a second position that is disposed in front of the first position.
