Mobile Device Holder with Segmented Hinges for Versatile Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mobile device holders are inconvenient when no table is available and have reduced durability due to increased rotation resistance from repeated use, limiting their utility in various environments.
Innovation Solution
A mobile device holder with a base part attached to the device, featuring first and second hinge pieces, horizontal hinge shafts, and pressing friction tubes to provide adjustable mounting options and maintain rotation resistance, enhancing durability and portability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional mobile device holder with a rotatable holding ring is used, then the device can be mounted on tables and flat surfaces, but the holder becomes difficult or impossible to use when no table is available and durability decreases due to increased rotation resistance
Solution Approach 1:
The holder is divided into multiple independent rotatable components: a first holder rotatable relative to the base part, and a second holder rotatable relative to the first holder. Each holder has its own hinge piece and rotation axis, allowing independent rotation without increasing overall rotation resistance. This segmentation resolves the contradiction by maintaining durability while enabling versatile mounting in various environments including vehicle seats and handles.
2Ease of operation
If the holding ring is repeatedly used for rotation, then the device can be adjusted to different positions, but rotation resistance decreases and durability is drastically reduced due to friction
Solution Approach 1:
The rotation function is segmented into multiple independent hinge joints. The first hinge piece connects the base part to the first holder, and the second hinge piece connects the first holder to the second holder. Each hinge operates independently with its own bearing surface, distributing the wear and friction across multiple contact points rather than concentrating it in a single holding ring, thereby maintaining durability while preserving rotation adjustability.
Solution Approach 2:
The holder structure incorporates multiple dynamic rotation joints that allow flexible adjustment. The first holder can rotate relative to the base part around a first rotation axis, and the second holder can rotate relative to the first holder around a second rotation axis. This dynamic multi-axis rotation system provides ease of operation while reducing stress on individual components, preventing the degradation of rotation resistance that occurs in single-ring designs.
