Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile robots are limited in the variety of services they can provide, and there is a need for improved systems that can accurately identify user body information and offer virtual fitting services with minimal user movement.
Innovation Solution
A mobile robot equipped with a driving unit, image acquisition unit, speech input unit, and display unit, which moves to a suitable position to acquire user images, scans the body, and creates an avatar with selected clothes, displaying a composite image on the display unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the robot uses image acquisition unit to scan user body, then body information identification accuracy is improved, but user movement requirement increases
Solution Approach 1:
Instead of requiring the user to move into position for scanning, the patent inverts the approach by moving the robot to the user. The controller automatically navigates the robot to optimal scanning positions around the user, capturing images from multiple angles while the user remains stationary, thus maintaining measurement precision while eliminating movement requirements
Solution Approach 2:
The patent transitions from a single-point scanning approach to multi-dimensional scanning by moving the robot around the user in different positions and angles. The controller manages movement in multiple spatial dimensions to capture comprehensive body images from front, side, and back views, achieving accurate 3D body information without requiring user movement
2Adaptability or versatility
If the robot provides multiple services including virtual fitting, then service versatility is improved, but device complexity increases
Solution Approach 1:
The patent implements multi-functionality by integrating body scanning, avatar creation, virtual fitting, and clothing recommendation services into a single robot system. The controller coordinates multiple units (image acquisition, speech input, display, driving) to deliver a complete virtual fitting service ecosystem, achieving high service versatility without proportionally increasing complexity through systematic integration
Solution Approach 2:
The patent uses copying by creating a digital avatar that replicates the user's body measurements and characteristics. This virtual copy enables multiple service applications (trying on different clothes, size recommendations, style suggestions) without requiring physical interaction with actual garments, reducing physical system complexity while expanding service capabilities
3Measurement precision
If the robot moves to acquire complete body images, then scanning accuracy is improved, but time consumption increases
Solution Approach 1:
The patent applies preliminary action by having the controller pre-calculate optimal scanning positions and movement paths before actual scanning begins. The robot proactively navigates to predetermined positions around the user, capturing images in an efficient sequence that minimizes total scanning time while ensuring complete body coverage and high measurement precision
Solution Approach 2:
The patent uses periodic action by implementing structured scanning cycles where the robot systematically moves to specific positions (front, side, back) at predetermined intervals. This periodic scanning pattern ensures comprehensive coverage for accurate measurements while maintaining efficient time management through automated, rhythmical movement and capture sequences
