Docking Unit Gap Formation for Portable Device Heat Dissipation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable information apparatuses face limitations in function extension due to reduced thickness, size, and weight, and insufficient heat dissipation when connected to external devices, leading to increased processing load and heat generation.
Innovation Solution
A docking unit with a detachable extension unit that creates a gap for air circulation and heat dissipation, utilizing air supply fans, power transmission devices, and magnetic mechanisms to securely hold and separate the units, ensuring effective heat dissipation while extending functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the extension unit is mounted on the back surface of the portable information apparatus to extend functions, then the function extension performance is improved, but the heat dissipation performance deteriorates because the back surface serves as the main heat dissipation portion
Solution Approach 1:
The invention divides the system into three separable components: the portable information apparatus, the extension unit, and the docking unit. The extension unit can be detached from the portable apparatus and separately docked with the docking unit, which provides dedicated heat dissipation resources. This segmentation allows the extension unit to access heat dissipation resources independently rather than competing for the portable apparatus's back surface.
Solution Approach 2:
The docking unit serves as an intermediary between the extension unit and the heat dissipation system. It provides a separate mounting location and dedicated heat dissipation resources (heat dissipation fins, air supply paths) that mediate the heat transfer process, allowing the extension unit to dissipate heat effectively without relying on the portable apparatus's back surface.
2Adaptability or versatility
If the portable information apparatus is connected to external devices for function extension and charging, then the function extension is improved, but the heat generation amount increases due to increased processing load
Solution Approach 1:
The invention extracts the extension unit from the portable information apparatus and provides it with separate heat dissipation resources through the docking unit. This extraction removes the heat generation problem from the portable apparatus system, allowing the extended functions to operate with their own dedicated cooling resources.
Solution Approach 2:
The invention transitions from a single-integrated heat dissipation approach to a multi-dimensional heat dissipation system. The docking unit adds a new spatial dimension for heat dissipation with dedicated fins and air supply paths, creating a parallel heat dissipation channel independent of the portable apparatus's original design.
3Weight of moving object
If the extension unit is designed with reduced thickness, size, and weight to match the portable information apparatus, then the portability is improved, but the function extension performance is limited
Solution Approach 1:
The invention creates a dynamic, reconfigurable system where the extension unit can transition between being mounted on the portable apparatus and being separately docked with the docking unit. This dynamic arrangement allows the extension unit to access additional resources (power, heat dissipation) when docked, enabling higher performance functions than would be possible in a permanently attached thin design.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The docking unit enhances heat dissipation performance of portable information apparatuses, preventing overheating and maintaining efficient operation during high processing loads by creating a gap for air circulation and using magnetic mechanisms to separate the units.
Implementation Method 1
a docking unit having a docking portion capable of docking an electronic apparatus in which a mounting surface of an extension unit is detachably mounted on a back surface of a portable information apparatus with the back surface of the extension unit on a top side, a holding portion holding the portable information apparatus at a predetermined position in a docking direction when the electronic apparatus is docked with the docking portion, and a forcibly moving portion forcibly moving the extension unit in the docking direction when the electronic apparatus is docked with the docking portion to thereby separate the extension unit from the portable information apparatus held with the holding portion to form a gap between the back surface of the portable information apparatus and the mounting surface of the extension unit
Implementation Method 2
a mounting magnet is provided on the mounting surface of the extension unit, a sticking target material to which the mounting magnet can be stuck is provided on the back surface of the portable information apparatus
Implementation Method 3
the forcibly moving portion has an attracting magnet which is provided on the bottom surface of the docking portion and attracts the mounting magnet from the back surface side of the extension unit
