Solution Overview

Problem

Wireless handheld devices face challenges with slow data transmission rates and limited battery life due to energy consumption from transmitting and receiving lengthy email messages.

Innovation Solution

Implementing techniques to download only the current portions of email messages without downloading historical portions, reducing energy consumption and potentially speeding up access to current message content by generating and transmitting truncated email messages that exclude historical content.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If wireless handheld devices download complete email messages including historical portions, then the user can access the full email content, but the energy consumption increases and battery life is shortened

Engineering Contradiction:

Improveemail content accessibilityVSAvoidenergy consumption

Core Design Contradiction:

Loss of informationVSUse of energy by moving object

Solution Approach 1:

The email message is divided into two distinct portions: a current portion containing only new information since the last download, and a historical portion containing previous content. The system transmits only the current portion to the wireless handheld device, allowing the user to access complete email content through a combination of the current portion and stored historical portions, thereby reducing energy consumption while maintaining information accessibility

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system extracts and transmits only the necessary current portion of the email message that contains new information, excluding the historical portion from the wireless transmission. This extraction approach reduces the amount of data transmitted over the wireless connection, directly lowering energy consumption while the device reconstructs the complete email by combining the extracted current portion with locally stored historical portions

Inventive Principle:

Principle #2Taking out (Extraction)

2Loss of information

If wireless handheld devices receive complete email messages, then the user can read the full message content, but the data transmission time increases due to slower transmission rates

Engineering Contradiction:

Improveemail content accessibilityVSAvoiddata transmission time

Core Design Contradiction:

Loss of informationVSLoss of time

Solution Approach 1:

The email message is segmented into current and historical portions, with only the current portion being transmitted wirelessly. This segmentation significantly reduces the amount of data that needs to be transmitted, thereby reducing data transmission time on the wireless connection while the complete email content is reconstructed by combining the received current portion with previously stored historical portions

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The historical portion of the email message is pre-stored in the wireless handheld device's memory. When a new email message arrives, the device already has the historical content available locally, so it only needs to receive and process the current portion, thereby reducing the overall time required to access the complete email content

Inventive Principle:

Principle #10Preliminary action

3Ease of operation

If wireless handheld devices transmit and receive lengthy email messages, then the user can communicate effectively, but the battery life is shortened

Engineering Contradiction:

Improveemail communication capabilityVSAvoidbattery life

Core Design Contradiction:

Ease of operationVSDuration of action of moving object

Solution Approach 1:

The email communication is segmented by transmitting only the current portion containing new information rather than the complete message. This reduces the amount of data that must be transmitted and processed over the wireless connection, thereby reducing energy consumption and extending battery life while maintaining effective email communication capability

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system extracts and transmits only the essential current portion of the email message, eliminating the need to transmit the entire message including historical content. This extraction approach reduces the energy consumption associated with wireless data transmission, thereby extending battery life while preserving the ability to communicate effectively through email

Inventive Principle:

Principle #2Taking out (Extraction)

AI summary

In general, this disclosure describes techniques of enabling devices to download only current portions of email messages without downloading historical portions of the email messages. For instance, when an email client generates a reply email message to an original email message, the reply email message includes a current portion and a historical portion. The current portion of the reply email message includes new information and the historical portion of the reply email message includes the original email message. The techniques of this disclosure enable devices to download the current portions of email messages without downloading the historical portions of the email messages.
