Mobile Database Energy Saving via Text Object Encoding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile devices face limited battery life and high energy consumption due to the need to support multiple applications, with existing methods inefficient in reducing energy usage, especially when archiving and searching data across multiple tables.
Innovation Solution
A method is introduced that involves encoding and formatting records from multiple related tables into compact text objects using a predefined character encoding scheme, storing them in a secondary energy-efficient storage, and using a parallel bit stream text processing application to reduce data access and search overhead, thereby conserving energy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If data is stored in traditional database tables with multiple related tables, then data structure and relationships are well-organized, but energy consumption increases due to complex data access and scrolling operations
Solution Approach 1:
The patent combines multiple related database tables into a single text file by extracting and concatenating record data. This merging eliminates the need for complex multi-table joins and scrolling operations, significantly reducing energy consumption while maintaining data accessibility through text-based search and processing.
Solution Approach 2:
The patent creates a text-based copy of database records that preserves the essential information while changing the storage format from structured tables to unstructured text. This copy allows for simplified access operations without losing the ability to retrieve and process original data relationships.
2Loss of time
If data is accessed through multiple related tables with joins, then data relationships are preserved, but data access time and energy consumption increase
Solution Approach 1:
The patent performs preliminary action by pre-extracting and concatenating data from multiple tables into a single text file before actual data access is needed. This preparation eliminates the need for time-consuming join operations during data retrieval, reducing both access time and associated energy consumption.
Solution Approach 2:
The patent extracts essential data from multiple related tables and consolidates them into a single text-based structure. This extraction removes the complexity of table relationships and joins, enabling faster and more energy-efficient data access while preserving the core information needed for processing.
3Ease of operation
If scrolling function is used to display search results, then all results can be viewed, but energy consumption increases significantly
Solution Approach 1:
The patent creates a text-based copy of database records that preserves the essential information while changing the storage format from structured tables to unstructured text. This copy allows for simplified access operations without losing the ability to retrieve and process original data relationships.
