Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the buckle device uses a complex structure with multiple grooves and protrusions for accommodating springs and fastening structures, then the fastening reliability is improved, but the device complexity increases and assembly becomes difficult
Solution Approach 1:
The vertical disk is divided into multiple independent components: the disk body, the spring accommodating groove, the protrusion structures, and the fastening elements. This segmentation allows each component to be manufactured and assembled separately, reducing overall assembly difficulty while maintaining the complex fastening functionality through coordinated interaction of simplified parts
Solution Approach 2:
The spring structures are nested within grooves of the vertical disk, and the protrusion structures are integrated into the disk body. This nesting approach allows complex fastening mechanisms to be compactly arranged within the vertical disk without increasing external dimensions, maintaining reliability while managing structural complexity through efficient space utilization
2Reliability
If the electromagnetic rods interfere with the vertical disks to prevent pressing body operation, then the locked state reliability is improved, but the user experience deteriorates due to inability to release the lock
Solution Approach 1:
The pressing body serves as an intermediary mechanism that transmits user force to the electromagnetic rods and vertical disks. When pressed, it mediates the interaction between the user and the electromagnetic locking mechanism, enabling controlled displacement of the electromagnetic rods from the vertical disks to achieve release while maintaining reliable locking during normal operation
Solution Approach 2:
The electromagnetic rods are designed to be dynamically positionable between two states: engaged with the vertical disk for reliable locking, and displaced from the vertical disk for release. The pressing body enables transition between these dynamic states, allowing the system to switch between high reliability locking and ease of release operation based on user input
3Measurement precision
If the staff must physically press the button to confirm locked state, then the confirmation accuracy is improved, but the social distance requirement is violated and germ spread risk increases
Solution Approach 1:
The mechanical confirmation method (physical pressing of buttons) is replaced with an optical detection system. Optical sensors or cameras detect the position and state of the buckle components, converting mechanical state information into optical signals for remote analysis. This substitution maintains confirmation accuracy through precise optical measurement while eliminating the need for staff to physically contact the buckle device, thereby preventing germ spread
