Portable Terminal Stand Accessory With Elastic Tube Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for accessory devices for portable terminals that can be easily adjusted between contraction and stand-up positions without interfering with carrying or charging, while maintaining the terminal at an appropriate angle for media consumption.
Innovation Solution
An accessory device featuring a body with legs and an elastic tube that surrounds the body, allowing it to be positioned in contraction or stand-up modes by applying forces along the longitudinal axis, with the elastic tube providing the necessary stability through different contraction states to maintain the desired position without full contraction or extension.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If the accessory device is designed to be slim and lightweight to match portable terminal trends, then portability is improved, but the ability to stably maintain the terminal at an appropriate angle for media consumption deteriorates
Solution Approach 1:
The accessory device employs a dynamic structure with movable legs that can transition between retracted and extended positions. The legs are connected through joints that allow movement, and the device can be switched between a compact state for portability and an extended state for stable media consumption positioning. This dynamic adaptability resolves the contradiction by providing both slim portability and stable positioning at different times.
Solution Approach 2:
The accessory device is divided into multiple segments including a body, multiple legs, and joints. Each leg can be independently positioned, allowing the device to distribute weight and provide stable support when extended while maintaining a compact form when retracted. This segmentation enables the device to achieve both portability and stability functions.
2Stability of the object's composition
If the accessory device is designed with a larger size and shape to stably maintain the portable terminal at an appropriate angle, then media consumption stability is improved, but interference with carrying or charging operations worsens
Solution Approach 1:
The accessory device transitions between a compact configuration for easy carrying and charging, and an extended configuration for stable media consumption. The legs can be retracted into the body to minimize interference during portability operations, and extended only when needed for viewing purposes.
Solution Approach 2:
The legs of the accessory device can be nested within or alongside the body when not in use, similar to nested dolls. This nesting capability allows the device to maintain a compact profile during carrying and charging operations, preventing interference while still providing the capability to extend for stable positioning when needed.
3Ease of operation
If the body is designed to contract fully to the end by applied force, then contraction position achievement is improved, but positioning precision and stability at intermediate positions deteriorates
Solution Approach 1:
The elastic tube provides continuous elastic force that acts as a feedback mechanism to maintain the body at a specific contracted position. When external force is applied to contract the body, the elastic tube resists with proportional elastic force, allowing the body to be held at various intermediate contraction positions with precision rather than forcing full contraction to the end.
Solution Approach 2:
The elastic tube changes its elastic parameters (force constant, expansion ratio) to provide appropriate resistance at different contraction positions. This allows precise positioning control by adjusting the balance between external applied force and internal elastic restoring force, enabling stable positioning at various contraction levels without requiring full contraction.
