Stepless Motion Mobile Phone Cover via Pushing Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional slidable mobile phones with a two-stage spring structure require external force to operate and suffer from damage over time, reducing user desire for collecting and using these devices due to rough tactile sensations.
Innovation Solution
A mobile phone with a stepless motion function, featuring a pushing device with a telescopic bar and cylinder body, where a fluid or elastic component enables the upper cover to move at a constant velocity between closed and opened positions, controlled by a pressing switch and fastening components, enhancing tactile sensation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a two-stage spring structure is used in the upper cover, then the mobile phone can achieve slidable motion, but the tactile sensation becomes rough and the structure is damaged after long-term operation
Solution Approach 1:
The patent replaces the traditional two-stage spring structure with a pushing device consisting of a telescopic bar and cylinder body. This substitution eliminates the rough tactile sensation and structural damage issues while maintaining the slidable motion function. The pushing device uses a more reliable mechanical system that provides smooth, controlled motion without the drawbacks of the spring-based approach.
Solution Approach 2:
The patent changes the operational parameters of the motion mechanism by introducing constant velocity control through the pushing device. Instead of the variable force characteristics of a two-stage spring system, the pushing device maintains consistent force application throughout the motion cycle, resulting in smooth tactile sensation and improved durability under repeated operation.
2Ease of operation
If a two-stage spring structure is used in the upper cover, then the mobile phone can achieve slidable motion, but external force is required to push the upper cover
Solution Approach 1:
The pushing device is designed to automatically provide the necessary force for upper cover motion without requiring continuous external input. The telescopic bar and cylinder body work together to self-regulate the pushing force, eliminating the need for users to manually overcome spring resistance and simplifying the operation to a single smooth motion.
3Ease of operation
If a pushing device with telescopic bar and cylinder body is used, then the upper cover moves at constant velocity improving tactile sensation, but the device complexity increases
Solution Approach 1:
The telescopic bar is nested within the cylinder body, creating a compact integrated pushing device. This nesting arrangement allows the complex constant-velocity mechanism to be contained within a space-efficient structure, minimizing the increase in overall device complexity while maintaining the smooth tactile sensation benefit.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The mobile phone's stepless motion function allows the upper cover to move at a constant velocity, improving tactile sensation and reducing wear and tear, thus increasing user satisfaction and durability.
Implementation Method 1
a fluid or an elastic component in the cylinder body can push the telescopic bar to enable the upper cover to slide at a constant velocity from the first position to the second position relatively to the mobile phone body
Implementation Method 2
a fluid or an elastic component in the cylinder body can push the telescopic bar to enable the upper cover to slide at a constant velocity from the first position to the second position relatively to the mobile phone body

AI summary
A mobile phone with a stepless motion function is provided and includes a mobile phone body, an upper cover which can be movably provided outside the mobile phone body, and a pushing device including a first end part and a second end part, wherein the first end part is fixedly provided at the upper cover, and the second end part is fixedly provided at the mobile phone body, whereby the upper cover can move at a constant velocity from a first position to a second position relatively to the mobile phone body. Therefore, the mobile phone with a stepless motion function of the invention enables the upper cover to move at a constant velocity at the mobile phone body to increase the tactile sensation of the mobile phone.
