Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If manual adjustment method using check bolt is used, then device complexity is reduced, but automation capability and positioning accuracy deteriorate
Solution Approach 1:
The anode is divided into multiple independent X-ray generation zones (first zone, second zone, third zone, etc.) that can be selectively positioned. Each zone can be independently selected and positioned facing the cathode, enabling automated selection of appropriate X-ray wavelengths for different analysis requirements.
Solution Approach 2:
A check member with multiple check surfaces is introduced as an intermediary component between the anode and the positioning mechanism. This check member, when pressed by the pressing member, selectively positions different X-ray generation zones facing the cathode through its multiple check surfaces, thereby automating the positioning process while maintaining reasonable device complexity.
2Manufacturing precision
If manual threading of check bolt is used, then manufacturing precision is reduced, but ease of operation is improved
Solution Approach 1:
The manual mechanical threading operation is replaced with an automated pressing mechanism. The pressing member automatically presses the check member to position the desired X-ray generation zone, eliminating the need for manual check bolt threading and achieving high positioning accuracy through controlled mechanical action.
Solution Approach 2:
The system is designed so that the pressing member automatically performs the positioning function when activated. The check member self-positions the anode zones through its multiple check surfaces that engage with corresponding positioning structures, making the process self-regulating and eliminating manual adjustment requirements.
3Measurement precision
If stopper device with multiple check surfaces is used, then positioning accuracy is improved, but device complexity increases
Solution Approach 1:
The check member serves multiple functions: it acts as a stopper with multiple check surfaces for positioning different zones, and it is actuated by the pressing member to enable automated selection. This multi-functional design achieves high positioning precision without requiring separate complex mechanisms for each function.
Solution Approach 2:
The check member combines multiple positioning functions into a single component. Its multiple check surfaces are integrated into one structure, allowing it to position multiple X-ray generation zones sequentially, thereby reducing the number of separate stopper devices needed while maintaining high positioning accuracy.
