Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile robots for daily use are limited in their ability to provide a variety of services due to their specific design, resulting in low utilization compared to development costs.
Innovation Solution
A mobile robot design featuring a thin and compact display unit with a robust structure, incorporating a vertically extending supporter to distribute the load of the display and rotating motor, and strategically positioning the speaker to minimize vibration effects, allowing for improved sound transmission and a more compact form factor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the display unit is made thin and compact, then the robot's form factor is improved, but the structural strength and load-bearing capacity deteriorate
Solution Approach 1:
The display unit is divided into multiple components: a front case, a rear case, and an intermediate support structure. This segmentation allows each part to be optimized independently - the front and rear cases can be made thin for compactness, while the intermediate support structure provides the necessary strength and load-bearing capacity.
Solution Approach 2:
The display unit employs composite construction with multiple materials having different properties. The front and rear cases use materials optimized for thinness and aesthetics, while the internal support structure uses materials with high strength-to-weight ratio to maintain structural integrity despite the overall compact design.
2Volume of moving object
If the speaker is positioned close to the rotating motor, then the display unit can be more compact, but vibration effects increase
Solution Approach 1:
A vibration isolation structure is introduced as an intermediary between the rotating motor and the speaker. This intermediate structure absorbs and dampens vibrations from the motor, preventing them from affecting the speaker while allowing both components to be positioned in a compact arrangement within the display unit.
3Adaptability or versatility
If multiple components are integrated into the display unit, then functionality is improved, but device complexity increases
Solution Approach 1:
The display unit is designed as a multi-functional integrated assembly where a single structural framework serves multiple purposes: it provides mechanical support, houses the rotating motor, positions the speaker, and supports the display screen. This universal structure reduces the number of separate components needed, thereby reducing overall complexity despite the enhanced functionality.
