Mobile Device Positioning with Segmented Securing Member
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fixers for handheld mobile devices are structurally weak, prone to deformation, and ineffective on vertical surfaces, leading to user discomfort and muscle fatigue during prolonged use, especially in public transportation.
Innovation Solution
A portable positioning device with a securing member that can easily attach to and detach from horizontal or vertical rods, providing overall rigidity and stability to suspend mobile devices, allowing users to operate them without displacement, featuring movable clamping jaws and adjustable locking units for secure engagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a flexible hose with clamp is used to suspend mobile device, then the device can be positioned over table, but the structure becomes weak and deforms after long term suspension
Solution Approach 1:
The positioning device is divided into separate functional modules: a rigid positioning frame for holding the device, a detachable securing member with clamping mechanism for attachment, and a support rod for structural integrity. This segmentation allows each component to be optimized for its specific function while maintaining overall reliability.
Solution Approach 2:
The positioning device combines rigid materials (for the positioning frame and support rod) with flexible components (securing member with elastic clamping jaws). This composite approach provides both structural stability for long-term suspension and adaptability for easy attachment/detachment to various surfaces.
2Adaptability or versatility
If clamp is designed for planar support only, then it works well on tables, but it cannot engage with vertical handrails in public transportation
Solution Approach 1:
The securing member is designed as a universal attachment mechanism that can engage with both planar surfaces (tables) and vertical cylindrical surfaces (handrails). The clamping jaws can adjust their orientation and apply force radially to accommodate different geometries, making the device versatile for multiple usage scenarios without increasing overall complexity.
Solution Approach 2:
The clamping mechanism incorporates movable clamping jaws that can dynamically adjust their position and orientation based on the shape of the attachment surface. This dynamic adaptability allows the same mechanism to effectively clamp both flat and curved surfaces, enhancing versatility while maintaining a relatively simple overall design.
3Ease of operation
If existing fixer is used to suspend mobile device, then device can be held over table, but user must use one hand to support device while operating with other hand
Solution Approach 1:
The positioning device separates the support function (positioning frame and support rod) from the attachment function (securing member). This segmentation creates a rigid support structure that can bear the device weight independently, enabling hands-free operation while maintaining operational stability.
Solution Approach 2:
The positioning device combines rigid structural components (positioning frame and support rod) with a flexible yet strong securing mechanism. This composite construction provides sufficient support rigidity to hold the mobile device steadily, allowing users to operate the device with one hand without needing to support it with the other hand.

AI summary
A positioning device working with a fixer for handheld, portable, mobile devices includes a securing member coupled to the fixer that serves to hold a mobile device in position. The securing member has a locking unit and a first connecting portion for engaging with the fixer. The securing member can secure the fixer onto an external article with the locking unit securing the securing member to the external article, so as to rapidly, removably suspend the mobile device at a nearby handrail. Thereby, the mobile device is strongly positioned over the external article by the locking unit and prevented from swinging or being displaced.
