Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a vertical articulated robot is used to move the nozzle, then the system can apply seal agent along three-dimensional work shapes, but the occupation area becomes large and control becomes complex
Solution Approach 1:
The moving device is segmented into multiple independent units: a movable unit that travels along guide portions, an elevating unit that moves vertically, and a posture changing unit that adjusts nozzle orientation. This segmentation allows each component to have a compact footprint while collectively achieving three-dimensional seal agent application capability.
Solution Approach 2:
The system uses a movable unit that travels along guide portions extending in a first horizontal direction, while the support portion extends in a second horizontal direction orthogonal to the first. This two-dimensional guide structure enables compact spatial arrangement while maintaining three-dimensional application capability through the elevating and posture changing units.
2Adaptability or versatility
If a vertical articulated robot is used to move the nozzle, then the system can apply seal agent along three-dimensional work shapes, but the control system becomes complex
Solution Approach 1:
The control system is segmented into three independent control units corresponding to the three functional units: movement control for the movable unit, elevation control for the elevating unit, and posture control for the posture changing unit. This segmentation simplifies control by breaking down the complex three-dimensional positioning task into three independent one-dimensional control problems.
Solution Approach 2:
The posture changing unit includes a first pivot mechanism and a second pivot mechanism that enable dynamic adjustment of the nozzle's orientation. The first pivot mechanism changes the tilting angle about a first axis, while the second pivot mechanism changes the tilting angle about a second axis, allowing adaptive positioning for three-dimensional work shapes.
3Adaptability or versatility
If the posture of the work is changed to apply seal agent, then seal agent can be applied along three-dimensional shapes, but the apparatus scale becomes large
Solution Approach 1:
Instead of changing the posture of the work to achieve three-dimensional seal agent application, the invention inverts the approach by keeping the work stationary and changing the posture of the nozzle through the elevating unit and posture changing unit. This inversion allows compact apparatus design while maintaining three-dimensional application capability.
Solution Approach 2:
The guide portions extend in a first horizontal direction, while the support portion extends in a second horizontal direction orthogonal to the first. This orthogonal arrangement in two horizontal dimensions, combined with vertical elevation, creates a compact three-dimensional workspace without requiring large apparatus scale.
