Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Individuals managing their own retirement accounts face challenges in optimizing asset allocation and contribution strategies due to the complexity of market conditions and changing retirement benefits, leading to overwhelming and complex recommendations from existing financial planning systems that deter users from enrolling in or continuing enhanced services.
Innovation Solution
A planning engine that receives user and account data, assigns asset class weights, calculates expected returns and standard deviations, and uses Monte Carlo simulations to generate account projections, leveraging a GPU for efficient computations and allowing multiple sets of initialization parameters without requiring system restarts, providing a user-friendly graphical interface for enhanced service levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional financial planning systems provide sophisticated tools and detailed recommendations, then the quality of financial planning improves, but the user interface complexity increases dramatically
Solution Approach 1:
The system segments the financial planning recommendations into multiple service levels (basic, intermediate, advanced) with progressively more detailed information. Users can select the appropriate service level based on their needs, preventing information overload while maintaining comprehensive planning capabilities when required.
Solution Approach 2:
The user interface dynamically adapts its complexity based on user interactions and selections. The system starts with simplified basic information and progressively reveals more detailed recommendations as users explore, ensuring the interface remains manageable while providing comprehensive planning tools when needed.
2Measurement precision
If financial planning systems generate comprehensive recommendations, then the planning quality improves, but the recommendations become overwhelming and too complex for ordinary users
Solution Approach 1:
The system divides comprehensive recommendations into discrete service levels (basic, intermediate, advanced), allowing users to access only the level appropriate for their knowledge and needs. This segmentation prevents overwhelming users with overly complex recommendations while maintaining comprehensive planning quality for those who seek it.
Solution Approach 2:
The system introduces simplified intermediate recommendations as a mediator between basic information and advanced planning details. This intermediate layer translates complex financial planning concepts into actionable advice that ordinary users can understand and implement without being overwhelmed by technical complexity.
3Measurement precision
If the planning engine performs extensive Monte Carlo simulations and calculations, then the projection accuracy improves, but the computational intensity and system downtime increase
Solution Approach 1:
The system performs preliminary calculations and pre-computes simulation results during off-peak times or in advance, storing the results for quick retrieval during user interactions. This preliminary action reduces the need for intensive real-time computations, thereby decreasing system downtime while maintaining projection accuracy.
Solution Approach 2:
The computational intensity dynamically adjusts based on user requests and service levels. The system performs extensive Monte Carlo simulations only when users request advanced projections or when data changes occur, rather than continuously running heavy computations. This dynamic approach maintains accuracy when needed while minimizing overall computational burden and system downtime.

AI summary
A planning engine for a financial planning system including at least one processor is provided. The at least one processor is programmed to receive user profile data and account data, assign an asset class weight to each of a plurality of asset classes associated with the account data, and retrieve an expected asset class return, an asset class standard deviation, and an asset class covariance. The processor is also programmed to generate a portfolio data object for each of the plurality of future years wherein the portfolio data object calculates (i) an expected portfolio return across the plurality of asset classes and (ii) a portfolio standard deviation across the plurality of asset classes. The processor is further configured to pass the portfolio data object to a monte carlo return object, receive, from the monte carlo return object, a matrix, and return an account projection derived from the matrix.
