Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a fixed tabbing process is used for solar cell modules, then the manufacturing process is simple and fast, but the distance between neighboring solar cells cannot be adjusted, affecting electrical connection efficiency
Solution Approach 1:
The patent implements a dynamic adjustment mechanism that allows the distance between shuttles (and consequently solar cells) to be variable during the tabbing process. The adjustment unit enables continuous modification of spacing parameters, transforming a static fixed-position system into a dynamic adjustable system, thereby resolving the contradiction between manufacturing simplicity and positioning precision.
Solution Approach 2:
The tabbing apparatus is divided into independent functional modules: multiple shuttles that can be individually positioned, an adjustment unit for controlling distances, and a tabbing unit for electrical connections. This segmentation allows each component to be optimized independently, enabling precise distance adjustment without requiring complete system redesign, thus balancing precision requirements with overall process simplicity.
2Reliability
If the distance between solar cells is not adjustable, then the tabbing process is straightforward, but electrical connectivity and module reliability are compromised
Solution Approach 1:
The adjustment unit incorporates feedback mechanisms that monitor and control the distance between shuttles, ensuring optimal spacing for electrical connectivity. By providing real-time feedback on position and distance parameters, the system maintains reliable electrical connections while keeping the operation process manageable through automated control, rather than requiring manual precision adjustment.
Solution Approach 2:
The adjustment unit acts as an intermediary between the shuttles and the tabbing process, mediating the distance control function. This intermediary component handles the complexity of distance adjustment, allowing the main tabbing operation to proceed with ease while ensuring that optimal spacing for electrical reliability is maintained through the intermediary's automated control functions.
3Manufacturing precision
If neighboring solar cells are positioned with imprecise spacing, then the tabbing process is faster, but manufacturing precision and module performance suffer
Solution Approach 1:
The adjustment unit performs preliminary positioning of shuttles before the actual tabbing operation begins. By pre-adjusting the distances between shuttles to precise values, the system eliminates the need for time-consuming manual adjustments during production, thereby maintaining both high manufacturing precision and productive speed throughout the tabbing process.
Solution Approach 2:
The patent replaces manual mechanical positioning with an automated adjustment unit that uses motorized or actuated mechanisms to control shuttle distances. This substitution of manual mechanical operations with automated control systems achieves precise spacing repetition without sacrificing production speed, as the automated system can rapidly and accurately adjust positions without the time penalties of manual intervention.
