Solution Overview
Problem
Existing robots designed for daily life are limited in their ability to provide a range of services, leading to inefficient cost utilization due to their specific service-oriented design.
Innovation Solution
A robot with a tilting mechanism that allows the backrest to be inclined and folded, incorporating a first tilting mechanism in the seat and a second tilting mechanism in the backrest, enabling the backrest to be adjusted between different inclinations, thereby enhancing versatility and user accessibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the backrest is fixed in position, then the robot structure is simple, but the robot cannot adapt to different service scenarios
Solution Approach 1:
The backrest is designed with tilting mechanisms that allow it to change its inclination angle dynamically. The first tilting mechanism enables the backrest to tilt relative to the seat, and the second tilting mechanism allows further adjustment of the backrest angle, transforming a static structure into a dynamic one that can adapt to different service scenarios.
Solution Approach 2:
By enabling the backrest to assume multiple inclination angles through the tilting mechanisms, the robot can serve multiple functions - providing comfortable seating when inclined at certain angles and restricting unauthorized use when folded to a specific angle, thereby achieving multi-functionality without requiring separate devices for each function.
2Reliability
If the backrest is made foldable to restrict unauthorized use, then security is improved, but the mechanism complexity increases
Solution Approach 1:
The tilting mechanism is divided into two independent segments: the first tilting mechanism (with cylinder and piston) that enables the backrest to tilt relative to the seat, and the second tilting mechanism that allows the backrest to fold relative to the link. This segmentation allows each mechanism to perform a specific function, making the overall system more manageable and reliable.
Solution Approach 2:
The tilting mechanisms are designed to automatically position the backrest at appropriate angles based on operational conditions. When the robot is not in use, the mechanisms enable the backrest to fold to a restricted position, preventing unauthorized use without requiring constant external monitoring or control.
3Ease of operation
If the backrest is inclined for user comfort, then user experience is improved, but the risk of unauthorized use increases
Solution Approach 1:
The backrest inclination is made dynamic rather than fixed. The tilting mechanisms allow the backrest to be inclined at comfortable angles during authorized use, but can be folded to a restricted position when the robot is not in use, automatically adapting to different operational states to balance comfort and security.
