Extendable Controller With Symmetric Dual-Carrier Clamping
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
An extendable controller design featuring a dual-reciprocating-opposite-motion-carrier system within an elongate bridge, allowing synchronous and symmetric extension and retraction of handle parts relative to the bridge, ensuring uniform movement and stable support for mobile devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single stack slider is used for extension, then the structure is simple, but the configuration becomes asymmetric resulting in unequal support and instability
Solution Approach 1:
The single stack slider is divided into two separate stack sliders (first stack slider and second stack slider) that operate independently on opposite sides of the mobile device. This segmentation allows each slider to provide symmetric support, eliminating the asymmetric configuration and instability caused by a single slider while maintaining structural simplicity through modular design.
2Device complexity
If asymmetric extension is allowed, then the structure is simpler, but the support becomes unequal causing wobbly and unstable clamped mobile phone experience
Solution Approach 1:
The patent applies asymmetry in reverse by creating a symmetric dual-slider configuration where both stack sliders are positioned symmetrically on opposite sides of the mobile device. This symmetric arrangement ensures equal backing support from both sides, eliminating the wobbly and unstable clamping experience while maintaining a relatively simple extension mechanism through the use of identical slider components.
3Device complexity
If a single stack slider is used, then the device is simpler, but the aesthetic appearance deteriorates when in use
Solution Approach 1:
The single stack slider is segmented into two symmetrically positioned stack sliders that extend and retract in unison. This segmentation creates a balanced, symmetric appearance when the mobile device is clamped, improving the aesthetic appearance by presenting a centered, harmonious configuration rather than the off-balance look produced by a single slider.
Solution Approach 2:
The patent uses symmetric design (reverse application of asymmetry principle) by positioning two identical stack sliders symmetrically on opposite sides of the mobile device. This creates visually balanced and aesthetically pleasing configuration during extension, transforming the appearance from asymmetric and丑ly to symmetric and elegant while maintaining mechanical simplicity.

AI summary
An extendable controller having a first handle part; a second handle part; an elongate bridge with a first half in sliding engagement with a first bridge-link portion of the first handle part and a second half in sliding engagement with a second bridge-link portion of the second handle part; and an extendable arrangement to synchronously extend and retract the first handle part and the second handle part uniformly in opposite directions relative to the elongate bridge along an extension axis. The extendable arrangement includes a dual-reciprocating-opposite-motion-carrier system having a first reciprocating carrier, a second reciprocating carrier, an opposite motion mechanism to move the first reciprocating carrier and the second reciprocating carrier in opposite directions with respect to the extension axis, a first elongate member coupling the first handle part to the first reciprocating carrier, and a second elongate member coupling the second handle part to the second reciprocating carrier.
