Rotating Shaft Linkage for Lift-Up Notebook Cooling Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing heat dissipation racks for electronic devices like notebook computers are cumbersome to use and store, and do not conveniently allow for the lifting of the device's rear side to enhance heat dissipation and user comfort.
Innovation Solution
A rotating shaft device comprising a base, a rotation member, a slide member, a supporting member, and a linkage unit, which allows the rotation member to pivot between positions, thereby sliding the supporting member and linkage unit to lift the rear side of the electronic device for improved heat dissipation and user comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a heat dissipation rack is used to lift the rear side of the notebook computer, then the heat dissipation space is increased and user comfort is improved, but the device becomes cumbersome to use and store
Solution Approach 1:
The heat dissipation rack is transformed from a static structure to a dynamic one that can automatically adjust its position. The rack is coupled to the rotation member through the linkage unit, allowing it to automatically lift when the rotation member rotates and to lower when the rotation member returns to its initial position, eliminating the need for manual operation and storage
Solution Approach 2:
The linkage unit is pre-configured with the rotation member and supporting member to create an automatic mechanical coupling. When the rotation member rotates, the linkage unit is already positioned to convert this rotational motion into linear motion that lifts the supporting member, preparing the system for automatic heat dissipation activation without additional user input
2Ease of operation
If the heat dissipation rack is designed to be compact for easy storage, then storage convenience is improved, but the heat dissipation space is reduced
Solution Approach 1:
The supporting member is designed to be slidable relative to the base, allowing it to extend outward to provide heat dissipation space and then automatically retract to a compact position. This dynamic positioning enables the system to switch between providing maximum heat dissipation space and maintaining a compact storage profile
Solution Approach 2:
The supporting member can be positioned to nest closely against the base when not in use, minimizing the overall footprint of the device for easy storage. When needed, it extends outward from the base to provide the necessary heat dissipation space, effectively nesting the heat dissipation function within the compact form factor
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 rotating shaft device effectively increases the space for heat dissipation and enhances user comfort by allowing easy lifting of the rear side of the electronic device, while also being easy to store when not in use.
Implementation Method 1
The linkage unit includes a first link that is pivotably connected to the base, a second link that is located at one side of the first link, and that is pivotably connected to the first link and the supporting member... When the rotation member is rotated to the second position, the slide member is urged by rotation of the rotation member to slide in the left-right direction and to convert the linkage unit into the expanded state, and the supporting member is urged by the second link of the linkage unit to slide to the supporting position

AI summary
A rotating shaft device includes a base, a rotation member, a slide member, a supporting member, and a linkage unit. The rotation member is rotatable relative to the base between a first position and a second position. The slide member is slidable relative to the base. The supporting member is slidable relative to the base between an initial position and a supporting position. The linkage unit is convertible between a folded state and an expanded state. When the rotation member is in the first position, the linkage unit is in the folded state and the supporting member is in the initial position. When the rotation member is rotated to the second position, the slide member is urged by the rotation member to slide and to convert the linkage unit into the expanded state, and the supporting member is urged by the linkage unit to slide to the supporting position.
