Seat Back Holder Elastic Strap Device for Stable Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for holding mobile phones and tablets in commercial vehicles during passenger transportation fail to securely maintain devices at the correct angle and stability, especially during vehicle movements, leading to potential drops and damage in accidents.
Innovation Solution
A mobile phone and tablet computer holder with an elastic strap system and rubber-made upper and lower holders, connected to the seat backrest via independent straps, ensuring secure positioning and minimizing impact in case of accidents by maintaining devices at eye level and accommodating various sizes without additional adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If trays are attached to the back of seats for positioning mobile phones and tablets, then devices can be positioned on the trays, but when the seat is reclined the trays cannot maintain their positions causing devices to drop or not be held with the right angle
Solution Approach 1:
The holder is divided into an upper holder and a lower holder as separate components, each capable of independent movement and positioning. This segmentation allows each holder to adapt to seat recline angles independently, maintaining device stability even when the seat position changes.
Solution Approach 2:
The holder incorporates elastic straps that allow dynamic adjustment and movement. The elastic components enable the holder to flex and adapt to different seat angles, maintaining secure device positioning regardless of seat recline position.
2Ease of operation
If pockets are attached to the seat back for positioning mobile phones and tablets, then devices can be placed in the pockets, but in the event of vehicle shaking the pockets cannot stably hold the devices causing them to fall down
Solution Approach 1:
The holder uses curved elastic straps that wrap around the device, providing conformal contact and secure holding. The elastic material deforms to match the device shape, creating a stable hold that resists vehicle motion and shaking.
Solution Approach 2:
The elastic straps change their physical parameters (tension, curvature, contact pressure) in response to device insertion and vehicle motion, automatically adjusting to maintain optimal holding force and stability under varying conditions.
3Reliability
If rigid holders are used to securely position devices, then devices can be held firmly, but in case of accidents the rigid structure cannot dampen impact causing potential damage to passenger head area
Solution Approach 1:
The holder uses elastic straps that inherently provide cushioning and impact absorption. The elastic material deforms under impact forces, dampening shocks before they can reach the passenger head area, while still maintaining secure device positioning during normal use.
Solution Approach 2:
The holder combines elastic materials with structural components to create a composite system that provides both secure holding and impact dampening. The elastic portions absorb impact energy while the structural elements maintain device positioning stability.
4Adaptability or versatility
If adjustable mechanisms are added to accommodate different device sizes, then various sizes of mobile phones and tablets can be positioned, but the device complexity increases requiring additional parts and adjustments
Solution Approach 1:
The elastic straps are designed to universally accommodate various device sizes and shapes through their inherent flexibility and elastic deformation. The same holder structure can secure different devices without requiring adjustment mechanisms or additional components.
Solution Approach 2:
The elastic straps change their physical parameters (length, curvature, contact area) to adapt to different device sizes. This parameter variation allows the holder to securely accommodate various mobile phones and tablets using the same basic structure.
