Flexible Holding Device With Elastic Tensioning Strap
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional holding devices for mobile devices are typically customized for specific device types and struggle to securely hold devices with varying external dimensions, limiting their adaptability.
Innovation Solution
A holding device made of flexible material with positioning features and an elastic tensioning strap that forms an abutment upon tightening, allowing it to securely hold mobile devices of different sizes by bending around their edges and maintaining tension, while also being cost-effective and lightweight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a holding device is customized for a specific type of mobile device, then it can securely hold that specific device, but it cannot adapt to devices with different external dimensions
Solution Approach 1:
The holding device incorporates an elastic tensioning strap that can dynamically adjust its length and tension to accommodate mobile devices of various dimensions. The strap transitions from a static fixed structure to a dynamic adjustable one, allowing the holding device to adapt to different device sizes while maintaining secure holding through elastic tension.
Solution Approach 2:
The elastic tensioning strap changes its physical parameters (length, tension force) based on the size of the mobile device being held. By adjusting the tension parameter, the holding device can securely hold both small and large devices without requiring multiple customized designs, thus resolving the contradiction between adaptability and reliability.
2Adaptability or versatility
If a rigid structure is used for the holding device, then it provides stable support, but it cannot flexibly adapt to different device geometries
Solution Approach 1:
The holding device replaces rigid structural components with an elastic tensioning strap that functions as a flexible element. This flexible strap can conform to different device geometries while the abutment structure provides the necessary stable support point, thus combining flexibility for adaptation with stability for secure holding.
Solution Approach 2:
The structure transitions from completely rigid to a dynamic system where the elastic strap can flex and adjust its shape to match different device geometries, while the abutment maintains structural stability to prevent the device from slipping out during use.
3Reliability
If multiple customized holding devices are manufactured for different device types, then each device can be held securely, but manufacturing costs and device complexity increase
Solution Approach 1:
The holding device with an elastic tensioning strap is designed as a universal solution that can securely hold multiple types of mobile devices with different dimensions. Instead of manufacturing separate customized holding devices for each phone model, this single multi-functional design replaces numerous variants, reducing device complexity while maintaining reliable holding capability across different device types.
