Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information systems fail to provide users with diverse and health-conscious dining options, limiting enjoyment and nutritional balance when choosing dishes outside their usual preferences.
Innovation Solution
An information provision system that stores dish nutritional information and user meal history, using this data to recommend non-uniform dishes and establishments based on nutritional needs, location, and user preferences, facilitating order and payment processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If users judge dishes based solely on uniform nutritional information, then health consciousness is improved, but user enjoyment and dietary diversity deteriorate
Solution Approach 1:
The system provides different types of information (nutritional info, taste preferences, price, location) with different weights to different users based on their individual needs and preferences, rather than treating all information uniformly for all users
Solution Approach 2:
The recommendation system dynamically adjusts dish recommendations based on changing user preferences, historical data, and contextual factors, making the system adaptable rather than static and uniform
2Measurement precision
If the system stores and processes detailed user meal history and nutritional data, then recommendation accuracy is improved, but system complexity increases
Solution Approach 1:
The system pre-processes and stores user meal history, nutritional data, and preference information in structured formats, so that when recommendations are needed, the data is already organized and ready for analysis, reducing real-time processing complexity
Solution Approach 2:
The system introduces an intermediate processing layer that manages the complexity of storing and analyzing user data, acting as a mediator between raw data collection and final recommendation generation
