Solution Overview
Problem
Existing mobile robots in public places are limited in their ability to provide personalized information and services due to their fixed functionality and lack of user-centric design, which restricts their ability to handle multiple user requests and efficiently manage heat dissipation without additional cooling systems.
Innovation Solution
A mobile robot design featuring a modular head system that allows for easy replacement and expansion of functions, integrated vent holes for passive heat dissipation during operation, and strategically positioned speakers for improved sound delivery to users, along with dual displays for enhanced user interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed functionality design is used, then the device structure is simple, but the ability to provide personalized information and services is limited
Solution Approach 1:
The robot system is divided into modular components including replaceable head modules, detachable display units, and separable functional attachments. This segmentation allows different functional modules to be combined and reconfigured based on service requirements, enabling personalized information delivery and services while maintaining relatively simple individual module structures.
Solution Approach 2:
The robot employs universal interfaces and standardized mounting mechanisms that allow a single base platform to support multiple functional heads and accessories. The display system can be configured in different positions and orientations, and the robot can switch between various service modes (guidance, information provision, entertainment) using the same hardware platform with reconfigurable software and modular attachments.
2Temperature
If additional cooling systems are added, then heat dissipation capability is improved, but device complexity increases
Solution Approach 1:
The cooling function is merged with the existing ventilation and speaker openings in the robot's housing. The same structural openings that serve acoustic and airflow functions are utilized for heat dissipation, eliminating the need for separate cooling system components. The robot's movement through public spaces naturally creates airflow that passes through these integrated openings, providing passive cooling.
Solution Approach 2:
The robot utilizes its own operational characteristics (movement, existing ventilation requirements for speakers) to achieve heat dissipation without additional active cooling systems. The natural airflow generated during movement and the existing speaker openings serve the dual purpose of acoustic output and thermal management, allowing the system to cool itself through its operational state.
3Ease of operation
If speakers are positioned for optimal sound delivery, then sound quality is improved, but device complexity increases
Solution Approach 1:
The speaker openings are strategically positioned at specific locations on the robot's body (front, rear, and side openings) to optimize sound delivery in different directions and situations. Each opening is located to serve specific acoustic requirements, with the front opening for forward-facing audio, side openings for lateral communication, and rear opening for backward audio output, creating localized optimal sound zones without complex positioning mechanisms.

Function Achieved in This Case
The mobile robot can efficiently handle multiple user requests, provide personalized services, and effectively manage heat without additional cooling systems, while ensuring clear sound delivery and improved usability in public environments.
Implementation Method 1
a vent hole formed at an upper side of the concave portion... During traveling of the driver, air is introduced into the body through the vent hole, so that heat inside the mobile robot 1 may be discharged outside

AI summary
A mobile robot includes a driver configured to provide a traveling function, a body disposed at an upper side of the driver and configured to include a head coupling hole formed at an upper portion thereof, and a head configured to include a head bracket inserted into the head coupling hole of the body. The body includes a head fixing frame fastened to the head bracket, a first bolt configured to fix the head fixing frame and the head bracket, and a repair cover coupled to an opening formed in a backward direction. The head is separated from the body when the first bolt is released by opening the repair cover.
