External Controller Heat Dissipator for Handheld Device Cooling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional external controllers for handheld devices lack an effective heat dissipation solution, leading to performance issues when the device is used for extended periods, especially during resource-intensive tasks like gaming.
Innovation Solution
The external controller incorporates a heat dissipator with a control circuit and a cooling interface, which can be a miniature fan or a voltage-driven cooler, to actively cool the handheld device during operation. The heat dissipator is integrated into the connection member and can be powered by the handheld device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If the handheld device is used for extended periods or resource-intensive tasks, then the device can perform gaming and other functions, but the device generates heat and temperature increases affecting performance
Solution Approach 1:
The patent introduces a heat dissipator as an intermediary component between the handheld device and the external controller. The heat dissipator includes a cooling interface that contacts the handheld device and a heat dissipation structure (such as a fan or thermoelectric cooler) that actively removes heat, serving as a mediator to transfer heat away from the device without requiring modification to the device itself.
Solution Approach 2:
The heat dissipation system is segmented into distinct functional components: a cooling interface that contacts the handheld device, a heat dissipation structure (fan or cooler) that actively removes heat, and a control circuit that manages operation. This segmentation allows each component to be optimized independently and facilitates integration into the external controller rather than the handheld device.
2Object-affected harmful factors
If a heat dissipator is added to the external controller, then heat dissipation capability is improved, but the device complexity increases
Solution Approach 1:
The external controller is designed with multi-functionality by integrating both control functions and heat dissipation functions into a single device. The connection member serves dual purposes: establishing electrical/communication connections and housing the heat dissipator. This universal design reduces the need for separate heat dissipation devices and simplifies the overall system architecture.
Solution Approach 2:
The patent merges the heat dissipation function with the external controller structure. The heat dissipator is integrated into the connection member that already exists for mounting and electrical connection, combining multiple functions (control, connection, and cooling) into a unified device rather than adding a separate cooling system.
3Temperature
If a heat dissipator is integrated into the connection member, then cooling effectiveness is improved, but the manufacturing complexity increases
Solution Approach 1:
The heat dissipator is pre-integrated into the connection member during manufacturing, with the cooling interface positioned to contact the handheld device when mounted. The control circuit is pre-wired to the power management circuit, and the heat dissipation structure is pre-assembled in its housing. This preliminary integration simplifies final assembly and ensures proper positioning without requiring complex alignment procedures.
Solution Approach 2:
The heat dissipator is designed to be self-contained within the connection member, with its own housing, mounting structure, and integration with the power management circuit. The cooling interface automatically contacts the handheld device when properly mounted, and the control circuit automatically receives power and control signals without requiring additional wiring or assembly steps.
