Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the head is directly coupled to the neck body without a tilting mechanism, then the structure is simple, but the robot cannot adjust head position for different services
Solution Approach 1:
The head assembly is segmented into a display body and a protrusion that couples to the tilting mechanism. The tilting mechanism itself is segmented into coupling bodies, supporters, and bearings. This segmentation allows the head to be independently tilted while keeping the overall structure manageable and modular.
Solution Approach 2:
The head position is made dynamic through the tilting mechanism that allows rotation between a first slope (display facing front/front upper side) and a second slope (display facing rear/rear upper side). The motor enables the head to adjust its angle dynamically based on different service requirements, transforming a static structure into a dynamic one.
2Ease of operation
If a motor is used to rotate the coupling body for tilting the head, then the head can be tilted smoothly, but the motor experiences high load from the head weight
Solution Approach 1:
The support frame and supporter structure are designed to bear the weight of the head, acting as a counterweight system. The bearing provided between the coupling body and the supporter further reduces the load on the motor by supporting the head's weight mechanically, allowing the motor to only provide the torque needed for rotation rather than supporting the entire weight.
Solution Approach 2:
The coupling body acts as an intermediary between the motor and the head. The motor rotates the coupling body, which in turn tilts the head through the protrusion-coupling hole connection. This intermediary structure allows the motor to operate at lower loads while still achieving smooth head tilting through the coordinated action of the coupling mechanism and bearing.
3Adaptability or versatility
If the display body is fixed in one position, then the structure is simple, but the robot cannot provide different services by adjusting head orientation
Solution Approach 1:
The tilting mechanism provides multi-functionality by enabling the robot to perform different services in different orientations. The head can be tilted to face the front during travel, face the rear upper side when stopped for user interaction, and adjust to appropriate angles for scanning barcodes or displaying information. This single mechanical mechanism supports multiple service modes, making the robot universal rather than specialized for one function.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The robot can efficiently switch between different service modes by adjusting its head position, improving user interaction and service flexibility while reducing the load on the motor, thus enhancing its overall utility and cost-effectiveness.
Implementation Method 1
The tilting mechanism may further include a bearing provided between the coupling body and the supporter.
