Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If translation members and sensors are used to align laminating sheets, then alignment capability is provided, but device complexity increases significantly
Solution Approach 1:
The patent extracts and eliminates the complex sensor systems and multiple translation members from the alignment device. Instead, it uses a single movable abutting element that can be positioned at different locations to define alignment references, thereby achieving alignment functionality with significantly reduced device complexity.
Solution Approach 2:
The movable abutting element serves multiple functions: it defines the front edge alignment reference, defines side edge alignment references when positioned at different locations, and provides physical contact for alignment. This multi-functional element replaces what would traditionally require multiple specialized sensors and translation members.
2Manufacturing precision
If multiple displacement operations are performed to achieve alignment, then alignment accuracy improves, but laminating speed decreases
Solution Approach 1:
The alignment reference is established in advance by positioning the movable abutting element at a predetermined location before the laminating process begins. This eliminates the need for multiple real-time displacement operations during laminating, as the reference is already prepared. The system only requires single displacement operations to match sheets against this pre-established reference.
3Measurement precision
If numerous sensors are deployed to detect relative positions, then alignment detection capability is enhanced, but device complexity and cost increase
Solution Approach 1:
The movable abutting element serves as both the alignment reference and the detection mechanism. When positioned at predetermined locations, it automatically defines the alignment references without requiring external sensors to detect positions. The element's physical presence and position itself provide the measurement function, making the system self-sufficient.
4Manufacturing precision
If cutting blades are used to trim cardboard to size, then alignment is achieved, but significant cardboard waste is generated
Solution Approach 1:
The alignment reference is established in advance using the movable abutting element at predetermined positions that correspond to the final desired sheet dimensions. This allows sheets to be aligned and laminated at full size without subsequent trimming, as the reference ensures correct positioning from the start, thereby preventing cardboard waste.
