Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If manual adjustment of occlusal strength is performed, then device complexity is reduced, but manufacturing precision deteriorates due to occlusion errors
Solution Approach 1:
The patent replaces the manual mechanical adjustment system with an automated system comprising a spindle adjustment unit, vertical moving unit, horizontal moving unit, and control unit. This automated mechanical-electrical system eliminates human error in adjustment while maintaining controlled complexity through modular design.
Solution Approach 2:
The system automatically adjusts the moving range of the upper spindle by changing parameters such as vertical position and horizontal position based on target occlusal thickness input. The control unit calculates and executes precise parameter changes to achieve desired occlusion without manual intervention.
2Device complexity
If manual adjustment is used, then device complexity is low, but productivity deteriorates due to increased manufacturing time
Solution Approach 1:
The system performs self-adjustment through automated units that independently execute positioning and adjustment tasks. The control unit autonomously calculates required adjustments and coordinates the spindle adjustment unit, vertical moving unit, and horizontal moving unit without requiring operator intervention for each adjustment.
Solution Approach 2:
The control unit pre-calculates the required adjustment parameters based on target occlusal thickness before execution. The system prepares adjustment paths and coordinates movements in advance, reducing actual adjustment time and improving manufacturing efficiency.
3Manufacturing precision
If automatic adjustment is implemented, then manufacturing precision is improved by eliminating occlusion errors, but device complexity increases
Solution Approach 1:
The adjustment apparatus is divided into functionally independent modules: spindle adjustment unit for precision positioning, vertical moving unit for height adjustment, horizontal moving unit for lateral positioning, and control unit for coordination. This segmentation allows each module to be optimized independently while maintaining overall precision.
Solution Approach 2:
The control unit serves multiple functions: receiving target occlusal thickness input, calculating required adjustments, coordinating all moving units, and monitoring the adjustment process. This multi-functionality reduces the need for separate control systems for each component.
4Productivity
If automatic spindle adjustment is used, then productivity is improved by reducing manufacturing time, but device complexity increases
Solution Approach 1:
The patent combines the spindle adjustment function with vertical and horizontal moving functions into an integrated adjustment apparatus. The control unit coordinates all movements simultaneously, reducing total adjustment time while sharing control infrastructure across all functions to manage complexity.
