Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Devices generating heat face challenges in effectively ventilating out heat due to insufficient size, position, or number of ventilation holes, which can lead to overheating and safety issues for both the device and surrounding humans/objects, despite the use of heatsinks and thermal conductors.
Innovation Solution
An arrangement with a cover having adjustable openings controlled by a controller, utilizing proximity, motion, and environmental sensors to optimize heat ventilation while ensuring safety, by dynamically changing the size of openings based on detected data to manage airflow and protect against environmental factors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the size of ventilation holes is increased to improve heat dissipation, then heat ventilation efficiency is improved, but safety of humans and protection from environmental factors (dust, moisture) deteriorates
Solution Approach 1:
The patent applies the dynamics principle by making the ventilation opening size adjustable rather than fixed. The controller dynamically changes the opening size based on detected heat conditions - increasing openings when heat accumulation is high to improve ventilation, and decreasing openings when heat levels are acceptable to protect against dust and moisture. This resolves the contradiction by allowing the system to optimize between heat dissipation and protection at different operational states.
Solution Approach 2:
The patent applies parameter changes by modifying the physical parameter of opening size based on thermal conditions. The controller monitors temperature or heat generation levels and adjusts the opening dimension accordingly - larger openings when thermal parameters indicate high heat, smaller openings when thermal parameters are within safe ranges. This enables adaptive optimization of both heat ventilation and environmental protection.
2Temperature
If the number of ventilation holes is increased to improve heat dissipation, then heat ventilation efficiency is improved, but device complexity increases
Solution Approach 1:
Instead of providing multiple fixed openings, the patent uses a dynamic adjustment mechanism that can modify the effective opening size. This single adjustable opening replaces what would otherwise require multiple fixed openings of varying sizes, thereby reducing device complexity while maintaining heat ventilation efficiency through controller-based size optimization.
Solution Approach 2:
The patent applies universality by making a single opening serve multiple functions that would otherwise require multiple specialized openings. By adjusting the size of one opening, the system can achieve the heat ventilation effect of multiple smaller openings while also maintaining structural simplicity and reducing the number of components needed.
3Device complexity
If fixed size openings are used to simplify device structure, then device complexity is reduced, but adaptability to different heat generation conditions deteriorates
Solution Approach 1:
The patent transforms a static, simple structure into a dynamic system that adapts to different heat generation conditions. The controller enables the opening size to change based on real-time thermal monitoring, providing adaptability to various operating conditions while maintaining relatively simple device structure through the use of a single adjustable opening rather than multiple fixed openings.
Solution Approach 2:
The patent applies feedback by using the controller to monitor heat generation conditions and adjust the opening size accordingly. The system continuously detects thermal states and provides feedback-driven adjustments to the opening dimension, enabling adaptability to different heat conditions while keeping the overall device structure simple through automated control rather than complex mechanical designs.
