Hinge Towing Mechanism for Dynamic Heat Dissipation and Keyboard Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
360-degree rotatable electronic devices face challenges in heat dissipation and dust prevention when transitioning between modes, as well as keyboard abrasion due to contact with surfaces during use.
Innovation Solution
The electronic device incorporates a hinge structure and towing mechanism with a moving component and elastic components, allowing for the exposure or concealment of heat dissipation holes and the positioning of protective pads to manage heat dissipation, dust prevention, and surface contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If heat dissipation holes are disposed on the case to dissipate heat to the outside, then heat dissipation performance is improved, but external dusts or foreign substances may enter into the host through these heat dissipation holes
Solution Approach 1:
The patent employs a movable component that can dynamically change the state of heat dissipation holes between exposed and covered positions. This dynamic mechanism allows the system to adapt between heat dissipation mode and dust prevention mode, resolving the contradiction by making the protective cover movable rather than fixed, enabling real-time adjustment based on operational requirements
Solution Approach 2:
The patent incorporates a towing structure with elastic components that preliminarily position the movable component to cover the heat dissipation holes when the device is in notebook mode. This preliminary protective action prevents dust entry before the device is actually used, while still allowing heat dissipation when needed by simply exposing the holes, thus proactively managing both heat dissipation and dust prevention requirements
2Stability of the object's composition
If the host is placed on the table surface with the operating surface in contact with the table surface, then the device is stable, but the keyboard may be inadvertently touched or abrasion on the keyboard may be generated
Solution Approach 1:
The patent introduces a movable component as an intermediary element between the keyboard and the table surface. This component includes protective pads that can be positioned to cover the keyboard area, acting as a mediator that prevents direct contact between the keyboard and potentially harmful surfaces, thus eliminating abrasion while maintaining device stability during operation
Solution Approach 2:
The protective pads are integrated into a movable component that can dynamically adjust its position based on usage scenarios. When the device is placed on a surface, the pads automatically position themselves to protect the keyboard; when the device is carried or used in other modes, the pads can be repositioned. This dynamic adaptability ensures keyboard protection is applied only when necessary, maintaining stability without unnecessary bulk
3Object-affected harmful factors
If a movable component is added to cover heat dissipation holes and protect the keyboard, then dust prevention and keyboard protection are improved, but device complexity increases
Solution Approach 1:
The movable component is designed to perform multiple functions simultaneously: it covers heat dissipation holes to prevent dust entry, positions protective pads to protect the keyboard from abrasion, and can be integrated with the towing structure to automatically respond to device orientation changes. By consolidating dust prevention and keyboard protection into a single multi-functional component, the patent reduces overall structural complexity compared to implementing separate mechanisms for each protective function
Solution Approach 2:
The patent merges the protective cover for heat dissipation holes and the protective pads for keyboard protection into a single integrated movable component. This consolidation combines multiple protective functions into one structural element, reducing the number of separate parts and simplifying the overall device architecture while maintaining comprehensive protection capabilities
