Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If non-linear deformation compensation is applied to align the component carrier structure, then alignment accuracy is improved, but manufacturing process compatibility deteriorates due to excessive distortion
Solution Approach 1:
The patent applies partial non-linear compensation by introducing a compensation limit that prevents full correction of non-linear deformations. This selective compensation approach corrects alignment errors within acceptable bounds while avoiding excessive distortion that would compromise manufacturing process compatibility, particularly for subsequent soldering and assembly operations.
Solution Approach 2:
The patent changes the parameter of non-linear compensation by introducing a maximum compensation limit. This parameter modification allows the system to balance between achieving sufficient alignment accuracy and maintaining compatibility with manufacturing processes, preventing over-correction that would create new problems.
2Measurement precision
If higher spatial accuracy is achieved through non-linear compensation, then alignment precision is improved, but system complexity increases
Solution Approach 1:
The patent implements partial non-linear compensation with a defined limit, avoiding the need for complex full non-linear compensation systems. This approach achieves sufficient alignment precision for practical applications while keeping the system complexity manageable by not attempting to correct all non-linear deformations.
