Robot Service Module Drawer Guide and Asymmetric Housing Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing robots designed for daily life provide limited services, resulting in low utilization compared to development costs, and there is a need for a robot capable of offering various services while minimizing the risk of overturning and maximizing space utilization.
Innovation Solution
A robot design featuring a mobile platform with a service module that includes multiple drawers and a locker system, where the drawers are designed to be inserted and locked within the housing, lowering the center of gravity and allowing for efficient use of space, with a display that rotates to facilitate user interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the robot is designed with a compact housing and multiple drawers for service modules, then space utilization is improved, but the center of gravity rises increasing the risk of overturning
Solution Approach 1:
The patent utilizes the vertical dimension by implementing multiple drawers stacked at different heights within the housing. This allows efficient use of vertical space while maintaining a compact footprint, resolving the contradiction between space utilization and stability by organizing storage compartments across different vertical levels rather than expanding horizontally
Solution Approach 2:
The housing is designed with an asymmetric profile where the horizontal length of the upper end is less than that of the lower end. This asymmetric geometry lowers the center of gravity by concentrating mass toward the bottom, thereby improving stability while still accommodating multiple drawers for service modules
2Adaptability or versatility
If existing robots are designed for specific services only, then service functionality is improved, but utilization rate decreases due to limited versatility
Solution Approach 1:
The robot is designed with a universal service module system comprising multiple drawers and a locker that can accommodate various service functions. The housing contains drawer guides and locking mechanisms that support different types of service modules, enabling the robot to perform multiple services (medicine delivery, supply transport, etc.) rather than being limited to a single function, thereby improving both versatility and utilization rate
3Adaptability or versatility
If multiple drawers are provided for service modules, then service capability is improved, but device complexity increases
Solution Approach 1:
The service system is segmented into multiple independent drawers and a locker, each capable of being locked and unlocked separately. This segmentation allows the robot to provide diverse service capabilities through modular compartments while managing complexity by dividing the system into discrete, independently controllable units with standardized mounting mechanisms
