Adjustable Support Device for Portable Electronic Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional portable electronic devices, such as notebook computers, face inadequate heat dissipation due to a fixed elevating structure that limits the height adjustment, resulting in insufficient thermal management and increased thickness.
Innovation Solution
A support device with a cam structure, first and second rod members, and a support member that adjusts the height based on the opening angle between the upper cover and base, allowing for variable elevation without increasing the device's thickness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If an elevating structure such as rubber salient points or plastic foot frames is disposed on the bottom surface of the base, then a gap between the base and desktop is reserved to improve heat dissipation, but the entire thickness of the notebook computer increases
Solution Approach 1:
The elevating structure is designed with adjustable height capability, allowing it to change from a fixed static structure to a dynamic one that can be adjusted according to different usage scenarios. The adjusting mechanism enables the elevating structure to provide different gap heights between the base and desktop, optimizing heat dissipation while maintaining a slim profile when not in use.
Solution Approach 2:
The adjusting mechanism is integrated within the elevating structure itself, with components nested inside each other. The adjusting member and limiting member are housed within the elevating structure's body, allowing the mechanism to be compact and not add excessive thickness to the overall device when in the retracted position.
2Device complexity
If an elevating structure with fixed height is used, then the structure is simple in design, but the height cannot be adjusted according to user requirements, reducing adaptability
Solution Approach 1:
The elevating structure transitions from a fixed static design to a dynamic adjustable one. The adjusting member can be moved between different positions by the user, enabling height customization while maintaining a relatively simple overall structure through the use of basic mechanical components like springs and limiters.
Solution Approach 2:
The height parameter of the elevating structure is made changeable through the adjusting mechanism. By moving the adjusting member to different positions along the elevating structure, the effective height can be varied to suit different user needs and usage scenarios, enhancing adaptability without requiring a completely complex system.
3Length of stationary object
If the height of the elevating structure is limited to 1.5 mm to 3 mm to avoid excessive thickness, then the device maintains a slim profile, but the heat dissipation assistance effect is limited
Solution Approach 1:
The elevating structure provides dynamic height adjustment capability, allowing users to select between a slim profile mode (when the adjusting member is in the lower position) and an enhanced heat dissipation mode (when the adjusting member is in the upper position). This enables the device to adapt its thickness based on the thermal management requirements of the specific usage scenario.
Solution Approach 2:
The elevating structure is divided into functional segments: a base portion that maintains the slim profile and an adjustable extension portion that can be extended when additional heat dissipation is needed. The adjusting member controls the extension of this segment, allowing the device to maintain its slim form factor during normal use while providing the option for enhanced heat dissipation when required.
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 adjustable support device enhances heat dissipation by varying the height of the portable electronic device, improving thermal management while maintaining a slim profile.
Implementation Method 1
The support device includes a cam structure, a first rod member, a second rod member, and a support member. The cam structure is connected to the pivot. The first rod member includes a first pivot portion, a stressed portion, and a first slide portion, where the first pivot portion is pivotally connected to the base shell, the first pivot portion is located between the stressed portion and the first slide portion, and the stressed portion and the cam structure are in contact with each other.
Implementation Method 2
One end of the pivot is connected to the base shell and the other end thereof is connected to the upper-cover shell. When the upper-cover shell is opened by means of the pivot relative to the base shell, the cam structure rotates
Implementation Method 3
the first slide portion and the second slide portion move relative to each other, and make the stress application portion of the second rod member to push the support member
