Tri-Body Electronic Device with Pivoting Display for Thermal Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Notebook computers have heat dissipation and battery life issues due to heat-generating elements, and the screen's proximity to the host limits user experience in terms of visual independence and perceived thinness.
Innovation Solution
The electronic device is designed with a first body supporting a display unit at an angle, allowing better heat dissipation and user experience by separating the display region, and includes a locking mechanism to maintain optimal angles for operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the screen is directly connected to the host and unfolded, then the device structure is simple, but the display region is too close to the host resulting in poor visual experience
Solution Approach 1:
The device is divided into three separate bodies: a first body (host), a second body (input unit), and a third body (display screen). The third body is pivotally connected to the first body, allowing the display to be spatially separated from the host while maintaining a compact folded state. This segmentation enables the display region to exist independently in space, improving visual experience.
2Stability of the object's composition
If the host is placed flat on a desktop surface, then the device is stable, but heat-generating elements cannot dissipate heat efficiently
Solution Approach 1:
The first body is designed to be expandable relative to the second body at a first predetermined angle, transforming the device from a flat configuration to a three-dimensional structure. This dynamic transformation allows heat-generating elements in the first body to be elevated away from the desktop surface, improving heat dissipation efficiency while maintaining stability through the pivotal connection and locking mechanism.
3Adaptability or versatility
If the host has functional assemblies such as keyboard module and battery module, then the device has complete functionality, but the host has large thickness resulting in poor sense of thinness and lightness
Solution Approach 1:
The device is segmented into three bodies with distinct functions: the first body contains heat-generating elements, the second body contains the input unit and battery module, and the third body contains the display screen. This segmentation allows each body to be optimized for its specific function while reducing the thickness of any single body, creating a sense of thinness and lightness when the device is in use.
Solution Approach 2:
The device transitions from a two-dimensional flat configuration to a three-dimensional structure when expanded. The first body is elevated at a predetermined angle relative to the second body, and the third body is elevated at a predetermined angle relative to the first body. This dimensional transformation reduces the effective thickness of the host when in use while maintaining complete functionality across all three bodies.
4Power
If heat-generating elements are present in the host, then the device has processing capability, but the battery heats up resulting in reduced battery life
Solution Approach 1:
The device separates heat-generating elements (processing unit in the first body) from the battery module (in the second body) through spatial segmentation. The pivotal connection allows the first body to be elevated away from the second body, creating physical distance between heat sources and the battery. This thermal isolation prevents heat transfer to the battery, maintaining battery life while preserving processing capability.

AI summary
An electronic device includes a first body, a second body and a third body. The first body includes a processing unit. The second body includes an input unit and is pivoted to an end of the first body. The third body includes a display unit and is pivoted to another end of the first body. When the third body is closed to the first body and the first body is closed to the second body, the electronic device is in a folded state. When the first body is expanded from the second body with a first predetermined angle, the third body is expanded from the first body with a second predetermined angle, such that the electronic device is in an operation state. When the electronic device is in the operation state, the third body is supported away from the second body by the first body.
