Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional blade holder structure is used, then the blade can be inserted for cutting, but the blade holder requires strict accuracy requirements and repeated adjustments to slide smoothly between circular rods, consuming much time and increasing assembly cost
Solution Approach 1:
The blade holder is divided into an upper blade holder and a lower blade holder that can be separately assembled and then connected together. This segmentation allows each part to be manufactured with standard tolerances and assembled without requiring strict overall position accuracy, thereby reducing assembly time and cost while maintaining operational smoothness
Solution Approach 2:
A positioning block is introduced as an intermediary component between the blade holder and the base. The positioning block provides precise positioning for the blade holder, eliminating the need for strict manufacturing precision on the blade holder itself. This mediator absorbs the positioning requirements, allowing the blade holder to be easily assembled and replaced without repeated adjustments
2Productivity
If a conventional blade holder structure is used, then the blade can be inserted for cutting, but repeated adjustments are necessary for the blade holder to slide smoothly, consuming much time and increasing assembly cost
Solution Approach 1:
The blade holder is divided into upper and lower parts that can be pre-assembled as a complete unit with the blade already installed. This segmentation allows the entire blade assembly to be replaced as one unit without requiring on-site adjustments, significantly increasing assembly speed and reducing the time lost to repeated positioning attempts
Solution Approach 2:
The positioning block is pre-installed on the base before the blade holder is assembled. This preliminary action ensures that when the blade holder is installed, it automatically receives accurate positioning without requiring any field adjustments, thereby eliminating time loss during assembly operations

AI summary
A paper corner protector cutter includes a base. The base is provided with a frame. The frame is pivotally connected with an operation rod. The operation rod is able to link a blade holder. The blade holder is provided with two blades. Two stop plates are disposed at two sides of the frame, enabling the blade holder to be located between the stop plates. Two stop plates are provided between the stop plates corresponding to the blade holder. The paper corner protector cutter can be assembled and positioned with ease by using a plate-type structure. The required time to assemble or disassemble the paper corner protector cutter can be decreased greatly to enhance the economic benefits.
