Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual adjustment is used to change projection direction, then device complexity is reduced, but ease of operation deteriorates
Solution Approach 1:
The projection apparatus employs dynamic rotation mechanisms allowing the projection body to rotate horizontally and vertically, transforming from a static to a dynamic structure. This enables automatic directional adjustment without manual intervention, resolving the contradiction between ease of operation and device complexity by making the system adaptive and self-adjusting
Solution Approach 2:
The projection apparatus performs self-adjustment through automatic rotation control, where the system itself carries out the directional adjustment without requiring external manual operation. This self-service capability improves ease of operation while the automation handles the complexity internally
2Productivity
If manual movement is used to achieve bidirectional projection, then device complexity is reduced, but productivity deteriorates
Solution Approach 1:
The dual-rotation mechanism (horizontal and vertical) transforms the static projection apparatus into a dynamic system capable of rapid bidirectional adjustment. This dynamic capability significantly improves productivity by enabling quick switching between different projection directions without manual relocation
Solution Approach 2:
The projection body is designed with multi-functional rotation capabilities, allowing it to perform both horizontal and vertical directional changes from a single position. This universality improves productivity by eliminating the need for manual movement while handling multiple projection scenarios
3Ease of operation
If automatic rotation control is implemented, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The patent replaces manual mechanical adjustment with automated rotation control systems. The first and second rotation mechanisms are controlled automatically, substituting human mechanical operations with automated control, thereby improving ease of operation while managing complexity through automation
Solution Approach 2:
The controller acts as an intermediary between the user and the rotation mechanisms, managing the complexity of dual-rotation control internally while presenting a simple interface to the user. This intermediary function resolves the contradiction by hiding the complexity behind automated control
