Portable Device Case with Suction Protrusions for Heat Dissipation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional portable electronic device cases often use straps that cause obstructions and are visually unappealing, and cases that are always affixed can lead to unwanted heat buildup during device operation.
Innovation Solution
A portable electronic device case design featuring a first case portion with a flexible hinge-like portion and support straps that allow axial motion, along with protrusion assemblies made of high-grade silicone suction cups to securely engage with the device's surface while allowing for air gaps to prevent heat buildup.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional cases use straps to secure the device, then the device is held firmly, but the straps cause obstructions and are visually unappealing
Solution Approach 1:
The patent removes the traditional strap component entirely and replaces it with protrusion assemblies that directly engage with the device surface. This extraction of the strap element eliminates the visual obstruction and structural complexity while maintaining the securing function through suction-based attachment.
Solution Approach 2:
The patent replaces the mechanical strap system with a suction-based protrusion assembly system. The protrusions use atmospheric pressure and adhesion forces rather than mechanical tension from straps, achieving device securing without the visual and structural drawbacks of traditional strap mechanisms.
2Reliability
If cases are always affixed to the device, then the device is securely held, but heat buildup occurs during device operation
Solution Approach 1:
The case is divided into multiple discrete protrusion assemblies rather than a continuous affixed structure. These segmented protrusions create localized attachment points that allow air circulation and heat dissipation in the gaps between them, preventing the heat buildup that occurs with fully affixed cases while maintaining secure device holding.
Solution Approach 2:
The protrusion assemblies provide localized attachment at specific points on the device surface rather than continuous contact. This local quality of attachment ensures secure holding where needed while leaving other areas open for thermal management, allowing the case to adapt its attachment characteristics to different functional requirements.
3Ease of operation
If protrusion assemblies use suction cups to engage the device, then the case can be easily attached and removed, but the suction force must be strong enough to prevent device detachment
Solution Approach 1:
The protrusion assemblies are designed with flexible bases that allow dynamic adjustment of the suction force. The flexible material deforms under compression to enhance the suction effect during attachment, then returns to its original shape to maintain consistent holding force during use, and allows easy release when detachment is needed. This dynamic behavior enables easy operation while maintaining sufficient suction force.
