Engineering Contradiction Analysis
1Reliability
If sub-circuit boards are connected using conventional circuit connection structures, then signal transmission between sub-circuit boards is achieved, but connection failures occur due to vibration or shaking during transportation or use
Solution Approach 1:
The patent applies preliminary anti-action by pre-configuring the circuit connection structure with specific geometric angles (first angle between first direction and board surface normal, second angle between second direction and board surface normal) that create inherent resistance to vibration-induced detachment. The connection terminals are positioned at predetermined angles before vibration occurs, so that when vibration happens, the force distribution naturally favors maintaining connection rather than causing detachment.
Solution Approach 2:
The patent changes the geometric parameters of the circuit connection structure, specifically the angles at which connection terminals are positioned relative to the board surfaces. By optimizing these angular parameters (first angle and second angle both between 0° and 90°), the structure achieves optimal force distribution during vibration, transforming the connection geometry to resist harmful vibrational forces.
2Stability of the object's composition
If connection terminals are positioned at optimal angles to resist vibration, then connection stability during vibration is improved, but the design complexity of the circuit connection structure increases
Solution Approach 1:
The patent applies local quality by modifying only the specific local geometry of the connection terminals and ports, rather than redesigning the entire circuit board structure. The angular positioning (first angle and second angle) is applied locally at the connection interface, leaving the rest of the circuit board structure unchanged. This localized modification achieves vibration resistance without proportionally increasing overall structural complexity.
3Reliability
If the spacing between circuit wirings is optimized for force distribution, then the probability of signal interruption is reduced, but the manufacturing precision requirements increase
Solution Approach 1:
The patent applies preliminary action by pre-establishing the optimal spacing between circuit wirings during the design and manufacturing phase. The spacing is calculated and set in advance to ensure that during subsequent vibration events, the force distribution among wirings remains within safe limits. This preliminary configuration of wiring spacing eliminates the need for complex real-time adjustments or extremely tight manufacturing tolerances during assembly.
