Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional robots lack the ability to adjust their display devices to match the eye level of users of varying heights, leading to ineffective communication and user interaction due to fixed display positions.
Innovation Solution
A robot equipped with a recognition unit and bending devices that allow the display device to rotate frontward, rearward, clockwise, and counterclockwise, utilizing pan/tilt driving units and sub units to adjust its position based on user eye detection, ensuring optimal alignment with the user's eyes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display device is fixed to the body at a predetermined height, then the structure is simple and stable, but the user's eyes cannot match the display device height, causing ineffective communication
Solution Approach 1:
The display device is transformed from a fixed structure to a dynamic adjustable structure through the bending device. The bending device includes multiple bending units with rotating joints that enable the display device to change its position and orientation dynamically, allowing it to adapt to different user heights and eye positions while maintaining effective communication.
Solution Approach 2:
The bending device is divided into multiple independent bending units (first bending unit, second bending unit, third bending unit) connected by rotating joints. Each bending unit can independently adjust its angle, providing multi-degree-of-freedom motion capability. This segmentation allows the complex adjustment function to be achieved through coordinated movement of simpler modular components.
2Adaptability or versatility
If the robot transforms to various postures to accommodate users of various heights, then user adaptability improves, but the conventional robot cannot achieve such transformation
Solution Approach 1:
The robot achieves posture transformation through the dynamic bending device that can adjust the display device to different heights and angles. The bending device's multiple rotating joints enable the robot to transform its effective display height to match users of various heights, providing adaptability without requiring the entire robot body to physically transform.
Solution Approach 2:
Instead of transforming the robot's overall body posture, the invention achieves height adaptation by adding dimensional flexibility to the display device through the bending device. The bending device provides adjustment in vertical height, horizontal angle, and rotational orientation, solving the adaptability problem through dimensional movement of the display component rather than whole-body transformation.
3Adaptability or versatility
If the display device rotates to match user eye position, then affinity and communication effectiveness improve, but the degree of freedom and flexibility requirements increase
Solution Approach 1:
The bending device is segmented into multiple independent bending units (first, second, and third bending units), each with its own rotating joint. This segmentation distributes the flexibility requirements across multiple simpler components rather than requiring a single complex mechanism, enabling the display device to achieve multi-directional rotation and positioning capability.
Solution Approach 2:
The bending device provides dynamic adjustability through its rotating joints, allowing the display device to rotate and reposition itself to match user eye positions. The dynamic nature of the bending units enables real-time adaptation to different users and viewing conditions, enhancing affinity and communication effectiveness.

AI summary
A robot rotates frontward, rearward, clockwise, or counterclockwise such that a display device is matched with the eye position of a user. The robot includes a body, a display device, and at least one bending device. The display device includes a recognition unit to rotate about the body according to the position of the user. The recognition unit detects a position of a user. The bending device couples the body with the display device such that the body and the display device rotate frontward, rearward, clockwise, or counterclockwise according to a detection state of the recognition unit.
