Dual-Mode Portable Accessory for Touch Control and Heat Dissipation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional notebook computers with integrated touch pads have limited space utilization and inefficient heat dissipation, requiring separate external mouse and heat dissipation pads that do not always match and occupy additional space, leading to suboptimal performance and carrying issues.
Innovation Solution
A dual-function accessory for portable electronic devices that can be selectively positioned to provide either touch control or heat dissipation, featuring a touch unit for input detection and a heat dissipation unit with a contact member, fan, and conductive tube to efficiently manage heat through a dedicated opening, allowing users to choose the function based on need.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If an external heat dissipation pad is placed externally of the notebook computer, then heat dissipation effect is improved, but space utilization is reduced and carrying becomes difficult
Solution Approach 1:
The patent combines the heat dissipation pad with the touch pad into a single integrated accessory. The touch pad unit and heat dissipation pad unit are merged into one device that can be selectively positioned, eliminating the need for separate external accessories and improving space utilization while maintaining effective heat dissipation.
Solution Approach 2:
The integrated accessory serves multiple functions: it acts as a touch control device during daytime and as a heat dissipation pad during nighttime or gaming sessions. This multi-functionality allows a single device to replace multiple separate accessories, improving adaptability and reducing the number of items needed.
2Measurement precision
If the touch pad is disabled when using an external mouse, then operational accuracy is improved, but space utilization of the touch pad is reduced
Solution Approach 1:
The accessory dynamically switches between two functional modes: touch control mode during the day and heat dissipation mode during nighttime or gaming. This dynamic adaptability allows the same physical space to serve different purposes at different times, effectively resolving the contradiction between operational accuracy and space utilization.
3Measurement precision
If a separate external mouse is used, then operational accuracy is improved, but the number of accessories increases and carrying becomes difficult
Solution Approach 1:
The patent merges the touch pad functionality with heat dissipation functionality into a single integrated accessory. This eliminates the need for separate external mice or heat dissipation pads, reducing the total number of accessories while maintaining operational accuracy through the touch control unit.
Solution Approach 2:
The integrated accessory provides universal functionality by serving as both a touch control device and a heat dissipation pad. This multi-functionality reduces the number of separate accessories needed, simplifying the overall system and improving portability.

AI summary
An accessory is selectively coupled in a first position or a second position to a portable electronic device. The accessory includes a touch unit and a heat dissipation unit. The touch unit is configured to be touched by a user to apply a contact force. An area of the touch unit to be touched by the user is defined as a contact point. When the accessory is in the first position, the touch unit detects a location of the contact point and outputs a control signal to the portable electronic device. The heat dissipation unit comes in contact with a heat source of the portable electronic device when the accessory is in the second position.
