Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional vacuum impregnation devices use separate storage tanks and moving inner cylinders, then the impregnation function is achieved, but the structure becomes complicated and construction cost increases
Solution Approach 1:
The patent merges the workpiece holder and the impregnation tank into a single integrated structure. The workpiece holder forms the tank body, eliminating the need for separate storage tanks and moving inner cylinders. This consolidation simplifies the overall structure and reduces construction costs while maintaining the impregnation function.
Solution Approach 2:
The workpiece holder serves multiple functions: it supports the workpiece during processing, forms the tank body structure, and provides the processing chamber. This multi-functional design eliminates the need for separate components, reducing structural complexity and manufacturing cost.
2Ease of operation
If traditional devices transfer glue between tanks or move inner cylinders, then impregnation is achieved, but operational complexity and cost increase
Solution Approach 1:
The impregnation liquid is pre-filled into the integrated tank body before the workpiece is placed. This eliminates the need for complex glue transfer operations between separate tanks during the impregnation process, simplifying operation and improving efficiency.
Solution Approach 2:
The patent extracts and eliminates the complex mechanisms for transferring glue between tanks or moving inner cylinders. By using an integrated structure with pre-filled liquid, these unnecessary moving parts and operational steps are completely removed.
3Reliability
If multiple components pass through the tank wall for operation, then control functions are achieved, but airtightness and robustness deteriorate
Solution Approach 1:
The patent uses an intermediary mechanism where the workpiece holder acts as a mediator between the external control system and the internal processing environment. Control functions are achieved through this intermediary structure without requiring multiple penetrations through the tank wall, thereby maintaining airtightness and robustness.
