Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for mobile device holders and positioners that do not interfere with the transmission and reception of signals to and from mobile device antennas, as existing solutions often use metallic components that can affect radio frequency (RF) performance.
Innovation Solution
A configurable mobile device holder with non-metallic components, including a body with cavities and multiple assemblies with moveable arms, sliders, and screws, designed to be coupled to different portions of the device without obstructing antennas, ensuring RF transparency and adaptability to various device sizes and shapes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If metallic components are used in mobile device holders, then structural strength and stability are improved, but radio frequency signal transmission and reception are interfered with
Solution Approach 1:
The patent removes metallic components from the holder structure and replaces them with non-conductive materials such as plastic or ceramic. This extraction of the harmful metallic element eliminates RF signal interference while maintaining the holder's structural function through appropriately designed non-conductive support elements.
Solution Approach 2:
The patent employs composite material construction for the holder, combining non-conductive materials (plastic, ceramic) with potentially conductive materials in a controlled manner where conductive elements are isolated or positioned to avoid RF interference zones. This allows structural strength to be maintained through material composition without compromising RF signal transmission.
2Ease of manufacture
If fixed-position holders are used, then manufacturing simplicity is improved, but adaptability to different mobile device sizes and shapes is reduced
Solution Approach 1:
The holder is divided into multiple independent adjustable segments or components, each capable of individual positioning. This segmentation allows the holder to be configured for different device sizes and shapes while maintaining relatively simple manufacturing of each individual segment, as each piece can be produced using standard processes.
Solution Approach 2:
The patent transitions from a static fixed-position holder to a dynamic adjustable holder where components can be repositioned along rails or guides. This dynamic capability enables adaptation to various mobile device configurations while the underlying structure remains based on simple, manufacturable elements like linear guides and adjustable clamps.
3Adaptability or versatility
If adjustable components with multiple parts are used, then adaptability to different devices is improved, but device complexity increases
Solution Approach 1:
The patent designs adjustable components that serve multiple functions simultaneously - for example, a single mechanism that provides both positioning and clamping functions, or a rail system that enables both lateral adjustment and vertical positioning. This multi-functionality reduces the number of separate parts needed compared to dedicated components for each function.
Solution Approach 2:
The patent combines multiple adjustment functions into integrated mechanisms, such as merging the positioning rail with the clamping structure, or combining rotation and translation capabilities in a single degree-of-freedom mechanism. This merging reduces overall structural complexity while maintaining full adjustability for different device configurations.
