Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the case is opened manually or with simple tools, then the operation is simple, but the case shakes or changes position during opening, reducing manufacturing precision and reliability
Solution Approach 1:
The patent employs suction portions with vacuum generators to create negative pressure that firmly holds the case in position during the opening process. The suction portions are positioned at multiple locations on the case to ensure stable fixation without manual handling, thereby preventing shaking or position changes while maintaining ease of operation.
Solution Approach 2:
The suction portions act as an intermediary between the opening apparatus and the case. Instead of direct mechanical contact that causes shaking, the vacuum field created by the suction portions mediates the interaction, providing stable positioning and enabling precise opening operations.
2Manufacturing precision
If the case is held firmly during opening, then position stability is improved, but the device complexity increases due to additional suction and rotation mechanisms
Solution Approach 1:
The patent combines multiple functions into integrated components: the suction portions serve both to hold the case in position and to prevent shaking during opening; the rotation driving portion integrates rotational motion with the opening action. This merging of functions achieves position stability without proportionally increasing device complexity.
Solution Approach 2:
The suction portions are designed to perform multiple functions: positioning the case, preventing shaking during opening, and maintaining stability throughout the opening process. This multi-functionality reduces the need for separate components, thereby limiting the increase in device complexity while achieving improved manufacturing precision.
3Manufacturing precision
If multiple suction portions are used to hold the case, then position stability is improved, but the device complexity and cost increase
Solution Approach 1:
The patent uses a sufficient number of suction portions to achieve stable positioning without over-engineering. The suction portions are positioned at critical locations on the case to provide adequate holding force, applying partial action only where necessary to prevent shaking and maintain position stability, thereby avoiding unnecessary complexity.
