Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If energy conversion devices are produced with complex design and manufacturing measures, then device complexity and production effort increase, but performance parameters still vary within tolerance corridors and cannot be predicted deterministically
Solution Approach 1:
The patent changes the approach from controlling individual device parameters to controlling combined system parameters. By evaluating and selecting devices based on their combined performance parameters in pairs or sets, the system achieves consistent overall performance even when individual device parameters vary within tolerance ranges. This parameter transformation resolves the contradiction by shifting focus from precise individual manufacturing to optimized system-level parameter combinations.
Solution Approach 2:
The patent segments the performance evaluation from the individual device level to the system level. Instead of requiring each energy conversion device to meet strict individual performance specifications, the system divides the performance requirement across multiple devices working together. This segmentation allows individual devices to have manufacturing variations while the combined system achieves the required performance consistency.
2Reliability
If individual energy conversion devices are required to meet strict performance specifications, then manufacturing effort and cost increase, but performance parameters still cannot be predicted exactly due to system complexity
Solution Approach 1:
The patent applies preliminary action by pre-evaluating and categorizing energy conversion devices based on their performance parameters before final assembly. Devices are measured, classified into performance groups, and paired or grouped in advance to ensure their combined performance meets specifications. This preliminary classification and matching process ensures reliable performance fulfillment while streamlining the final assembly process, thereby maintaining productivity.
Solution Approach 2:
The system implements feedback by measuring actual performance parameters of energy conversion devices and using this information to guide the pairing and selection process. Performance data from individual devices feeds into the combination algorithm, which adjusts pairings to achieve the desired combined performance. This feedback loop ensures specification fulfillment while optimizing production efficiency by avoiding trial-and-error assembly.
3Ease of manufacture
If energy conversion devices are selected individually without considering combined performance, then production is simpler, but the technical system may not meet required performance thresholds
Solution Approach 1:
The system applies self-service by allowing the performance data of individual devices to automatically guide their own pairing and selection. Each device's measured performance parameters serve as input that determines its optimal companions in the system. This self-referential approach simplifies the manufacturing process by using the devices' own characteristics to determine their placement, while simultaneously achieving high combined performance accuracy through algorithmic optimization.
4Measurement precision
If performance parameters are required to have exact values, then manufacturing precision requirements increase, but actual parameters end up in tolerance corridors due to system complexity
Solution Approach 1:
The patent merges multiple individual device performance parameters into a single combined performance parameter for evaluation. Instead of requiring each device to have an exact performance value, the system combines the performance of multiple devices (e.g., pairs of energy conversion devices) and evaluates the aggregate. This merging approach maintains measurement precision at the system level while accommodating the natural tolerance variations of individual complex devices.
