Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the robot uses a fixed ribcage structure, then the structure is simple and stable, but the robot cannot transform between car and human forms
Solution Approach 1:
The ribcage structure is designed with dynamic characteristics, allowing it to change configuration between car and human forms. The first steering gear enables the ribcage to rotate relative to the second fixing frame, transforming the static structure into a dynamic one that can adapt to different operational modes.
Solution Approach 2:
The ribcage structure is divided into separable components: a first fixing frame, a second fixing frame, and a rotating connection mechanism with the first steering gear. This segmentation allows independent movement and transformation of parts, enabling the robot to switch between car and human forms while managing structural complexity.
2Adaptability or versatility
If the robot includes a retractable head structure, then the transformation between forms is more complete, but the device complexity increases
Solution Approach 1:
The head structure is designed to be retractable into the ribcage structure, similar to a nested doll configuration. When the robot transforms to car form, the head retracts into the ribcage; when transforming to human form, the head extends outward. This nesting principle allows complete form transformation while managing space and structural complexity.
Solution Approach 2:
The head structure incorporates dynamic movement capabilities through retraction and extension mechanisms. This dynamic design allows the head to adapt its position based on the robot's operational mode, enabling complete transformation between car and human forms.
3Ease of operation
If the robot uses symmetrical arm and leg structures, then the biped walking capability is improved, but the device complexity increases
Solution Approach 1:
While the overall arm and leg structures are symmetrical for balanced biped walking, the internal steering gear mechanisms may have asymmetric configurations optimized for specific movement patterns. This allows the external symmetry needed for walking while incorporating asymmetric mechanical advantages within the components.
Solution Approach 2:
The arm and leg structures use universal steering gear mechanisms that can perform multiple functions: supporting biped walking in human form and providing wheel rotation in car form. This multi-functionality reduces the need for separate mechanisms for different operational modes, managing complexity while enabling diverse capabilities.
