Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If users manually set up Pivot Tables or program in embedded languages to perform two-dimensional repetitive calculations, then the calculations can be performed, but the complexity of operation increases and errors occur more frequently
Solution Approach 1:
The patent creates a simplified copy of the Pivot Table functionality through predefined spreadsheet functions. Instead of requiring users to manually configure complex Pivot Tables or write embedded code, the invention provides pre-built functions that replicate the essential calculation capabilities, making them accessible through simple formula entry while maintaining calculation accuracy
Solution Approach 2:
The predefined functions automatically perform two-dimensional repetitive calculations without requiring user intervention for each iteration. The functions self-configure based on input parameters, eliminating the need for manual setup and reducing operational complexity while maintaining reliability through consistent automated execution
2Productivity
If users manually set up Pivot Tables or program in embedded languages, then two-dimensional calculations can be performed, but the number of steps required increases
Solution Approach 1:
The patent pre-configures calculation templates and functions with built-in logic for two-dimensional repetitive calculations. By preparing the computational framework in advance through predefined functions, users only need to provide input data and parameters, dramatically reducing setup time while maintaining high calculation efficiency for complex operations
Solution Approach 2:
The predefined spreadsheet functions are designed to handle multiple types of two-dimensional calculations through a single unified interface. These multi-functional functions can perform various repetitive calculations across different data structures and scenarios, eliminating the need for separate setup procedures for each calculation type and significantly improving productivity
3Adaptability or versatility
If users manually configure Pivot Tables for repetitive calculations, then calculations can be performed, but the complexity of the device increases
Solution Approach 1:
The patent breaks down complex two-dimensional calculation tasks into manageable segments handled by predefined functions. Each function handles a specific aspect of the calculation (such as iteration, aggregation, or filtering), allowing users to combine these segmented functions in flexible ways to adapt to different calculation needs without confronting the full complexity of manual Pivot Table configuration
Data Source
AI summary
The disclosed technology creates a family of (predefined formula) spreadsheet functions which allows users to create programming loop equivalents in their regular spreadsheet cells employing familiar range functions (e.g., SUM, COUNT, MIN, MAX, etc.) with data filtering and output selection. The data can be sourced from multiple cells within the spreadsheet or a broad spectrum of numeric, date and text data not stored in a spreadsheet, including data not discretely defined. The technology disclosed can use as inputs either cell ranges or Non-Spreadsheet Cell (NSC) data formulas. The capability allows users to specify standardized or highly custom calculations capable of executing millions of loops through a (predefined formula) spreadsheet function.
