Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a heat dissipation rack is used to lift the rear side of the notebook computer, then heat dissipation space is increased and user comfort is improved, but the rack is difficult to use and store, and stability is inadequate
Solution Approach 1:
The patent applies the dynamics principle by designing a mechanism with movable components including a rotation member that can rotate between first and second rotation positions, a slide member that can slide between first and second slide positions, and a supporting member that can move between initial and supporting positions. These dynamic components enable the heat dissipation rack to transition between compact storage state and expanded support state, resolving the contradiction between ease of use and device complexity.
Solution Approach 2:
The patent segments the heat dissipation rack into multiple independent functional components: a base, a rotation member, a slide member, a resistance-providing member, and a supporting member with linkage unit. Each component performs a specific function and can move independently, allowing the system to achieve both compact storage and stable support when needed.
2Area of stationary object
If a heat dissipation rack is used to lift the rear side of the notebook computer, then heat dissipation space is increased, but stability of the rack is inadequate
Solution Approach 1:
The patent applies preliminary action through the resistance-providing member that is pre-configured to provide resistance force when the slide member moves to the second slide position. This preliminary resistance mechanism ensures that once the supporting member is positioned, it maintains stability and prevents unintended collapse under the weight of the notebook computer.
Solution Approach 2:
The patent introduces a linkage unit as an intermediary mechanism connecting the rotation member, slide member, and supporting member. The linkage unit includes a first link pivotally connected to the base, a second link pivotably connected to the first link and supporting member, and a linkage engaging structure that couples to the slide guiding structure. This intermediary linkage transmits and coordinates the movements of multiple components to achieve stable support.
3Stability of the object's composition
If the slide member is positioned to provide support, then stability is improved, but the device becomes difficult to store
Solution Approach 1:
The patent applies dynamics by designing components that can transition between different positional states. The rotation member rotates between first and second rotation positions, the slide member slides between first and second slide positions, and the supporting member moves between initial and supporting positions. This dynamic capability allows the device to achieve compact storage volume when not in use while providing stable support when needed.
Solution Approach 2:
The patent implements nesting by arranging the components so that when in the storage state (first rotation position, first slide position, initial position), the supporting member and linkage unit are positioned within or adjacent to the base and rotation member, minimizing the overall volume occupied by the device.
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 device facilitates easy storage and enhances stability by allowing the notebook computer to be lifted conveniently, providing increased space for heat dissipation and user comfort while preventing the supporting member from collapsing under the device's weight.
Implementation Method 1
The resistance-providing member interconnects the slide member and the base, and provides a force that prevents the slide member from moving toward the first slide position when the slide member is in the second slide position
Implementation Method 2
The rotation member is disposed on the base, and is rotatable relative to the base about a rotation axis between a first rotation position and a second rotation position
Implementation Method 3
The slide member is disposed on the base, and is slidable relative to the base between a first slide position and a second slide position in the left-right direction
Implementation Method 4
The supporting member is disposed on the base, and is movable relative to the base between an initial position and a supporting position

AI summary
A rotating shaft device includes a base, a rotation member, a slide member, a resistance-providing member, a supporting member, and a linkage unit. The rotation member is rotatable relative to the base between a first rotation position and a second rotation position. The slide member is slidable relative to the base between a first slide position and a second slide position. The resistance-providing member prevents the slide member from moving toward the first slide position when the slide member is in the second slide position. The supporting member is movable 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 rotation position, the slide member, the linkage unit, and the supporting member are respectively in the first slide position, the folded state, and the initial position.
