Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing game controllers for mobile devices often result in asymmetric configurations when extended, leading to unequal support and instability, causing user irritation and aesthetic issues.
Innovation Solution
A symmetrically extendable controller design featuring a dual-reciprocating-opposite-motion-carrier system and pulley mechanism that synchronously extends and retracts handle parts in opposite directions, maintaining a central midpoint, ensuring uniform and stable attachment of mobile devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single stack slider is used for the clamping mechanism, then the structure is simple, but the configuration becomes asymmetric when extended, resulting in unequal backing support and instability
Solution Approach 1:
The clamping mechanism is divided into two separate stack sliders (first stack slider and second stack slider) instead of using a single stack slider. Each stack slider independently controls one handle part, allowing symmetric extension and retraction. This segmentation enables both handles to be pulled away uniformly, maintaining symmetric configuration and stable backing support for the mobile device.
Solution Approach 2:
The patent applies asymmetry in reverse by designing a symmetric system. The first and second stack sliders are positioned symmetrically on opposite sides of the elongate bridge, and their motion is coordinated to maintain symmetry during extension and retraction. This symmetric design directly counteracts the asymmetric configuration problem caused by single stack slider mechanisms.
2Device complexity
If handle parts are extended asymmetrically, then the extension mechanism is simple, but the mobile device becomes wobbly and unstable
Solution Approach 1:
The system incorporates a feedback mechanism where the motion of one stack slider is linked to the motion of the other through the control system. When one handle part is extended or retracted, the feedback mechanism ensures the other handle part moves accordingly, maintaining symmetric configuration. This coordinated motion prevents wobbly and unstable attachment, improving reliability of mobile device securing.
3Stability of the object's composition
If a symmetric extension mechanism is implemented, then stability and aesthetics are improved, but the device complexity increases
Solution Approach 1:
The patent merges the control functions of both stack sliders into a unified extendable arrangement. The first and second stack sliders are interconnected through the elongate bridge and control system, allowing them to operate as a coordinated unit. This merging enables symmetric extension and retraction while managing the complexity through integrated design, where the two sliders work together rather than independently.
4Ease of manufacture
If asymmetric configuration is used, then manufacturing is simpler, but the aesthetic appeal deteriorates
Solution Approach 1:
The first and second stack sliders are designed as universal, interchangeable components with identical structure and function. Both sliders perform the same clamping and extension functions, allowing for standardized manufacturing processes. This universality maintains aesthetic symmetry while simplifying manufacturing, as the same component design can be produced repeatedly using the same tooling and assembly procedures.

Function Achieved in This Case
The design provides stable, symmetrical extension and retraction of handle parts, enhancing user experience by maintaining device stability and aesthetics while supporting mobile devices uniformly.
Implementation Method 1

Implementation Method 2
a continuous endless belt looped over the first pulley and the second pulley
