Solution Overview
Problem
Existing electronic display boards and information boards in public places are limited in providing users with desired information, as they are unilateral and require human guidance, which can be costly and inefficient in delivering information to multiple users.
Innovation Solution
A mobile robot with a driver, vent holes for heat dissipation, and a modular head system that can be easily replaced, equipped with displays and speakers for efficient information delivery and user interaction, capable of handling multiple users and providing guidance, cleaning, and management services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a mobile robot is used to provide information to multiple users, then labor costs are reduced and service coverage is improved, but the robot generates heat that requires effective dissipation
Solution Approach 1:
The robot body is divided into functional modules including a detachable head module, allowing the robot to maintain a compact core while having separate components for specific functions. The vent hole system is segmented into multiple openings distributed across the robot body to optimize heat dissipation from different heat-generating components
Solution Approach 2:
The head module is extracted as a separate, detachable component from the robot body. This allows the head module to be removed or replaced independently, enabling maintenance, upgrades, or adaptation of the information display and interaction components without affecting the core robot structure or heat dissipation system
2Adaptability or versatility
If the head module is made detachable for functional expansion, then adaptability is improved, but the structural complexity increases
Solution Approach 1:
The robot is segmented into a permanent body and a detachable head module, with standardized connection interfaces that simplify the assembly and disassembly process. This modular approach enables functional expansion through head module replacement while keeping the structural complexity manageable through standardization
Solution Approach 2:
The head module is designed as a universal interface that can be attached to or removed from the robot body through standardized connectors. This universal design allows the same head module to serve multiple functions or be replaced with different modules for different applications, improving adaptability without proportionally increasing complexity
3Temperature
If vent holes are added for heat dissipation, then temperature control is improved, but the aesthetic appearance and sealing are worsened
Solution Approach 1:
Vent holes are strategically positioned in specific locations on the robot body where heat dissipation is most needed, rather than uniformly distributed. The guide inclined surface is designed with specific angular characteristics to optimize airflow direction. This localized approach to ventilation maintains aesthetic appearance in visible areas while ensuring effective heat dissipation from internal components

Function Achieved in This Case
The mobile robot effectively reduces labor costs by providing personalized information to multiple users while maintaining efficient operation and heat management without the need for additional cooling systems, enhancing user interaction and service capabilities in public spaces.
Implementation Method 1
During traveling of the driver, air may be introduced into the body through the vent hole

AI summary
A mobile robot includes a driver configured to provide a traveling function, a body disposed at an upper side of the driver, a concave portion recessed inward from a surface of the body, a vent hole formed at an upper side of the concave portion, and a guide inclined surface formed at a lower side of the concave portion. During traveling of the mobile robot, the mobile robot induces inflow of air so that the body can be cooled.
