Pistol Grip Mobile Device Trigger Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile devices with a gun grip form factor require an efficient and intuitive control mechanism for single-handed operation, as existing trigger controls often limit functionality and user interaction.
Innovation Solution
A mobile device design featuring a pistol grip housing with a trigger-like control switch and integrated pointing device, such as a miniature joystick, trackball, or touchpad, allowing for single-handed operation and control of various functions like swiping, scrolling, zooming, and data capture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a simple trigger control is used for single-handed operation, then ease of operation is improved, but device functionality is limited
Solution Approach 1:
The patent combines a trigger control mechanism with a pointing device (joystick, trackball, or touchpad) into a single integrated control assembly. This merging allows the device to maintain simple single-handed operation while significantly expanding functionality to include both triggering actions and directional control, resolving the contradiction between ease of operation and device versatility.
Solution Approach 2:
The control mechanism is designed to perform multiple functions: the trigger can activate functions independently, while the pointing device enables swiping, scrolling, zooming, and selection operations. This multi-functional design allows a single control assembly to replace what would traditionally require separate controls, thereby improving both ease of single-handed operation and overall device functionality.
2Adaptability or versatility
If multiple control mechanisms are added to enhance functionality, then device versatility is improved, but device complexity increases
Solution Approach 1:
Instead of adding separate controls for triggering and pointing operations, the patent merges these functions into a single integrated control assembly where the pointing device and trigger share the same physical space and operational context. This consolidation reduces the number of separate components and simplifies the overall control architecture while maintaining full functionality.
Solution Approach 2:
The integrated control assembly is designed as a universal control unit that can perform multiple operations (triggering, swiping, scrolling, zooming, selection) through a single mechanism. This multi-functional design reduces device complexity by eliminating the need for multiple specialized controls, while still providing comprehensive functionality for single-handed operation.

AI summary
A mobile device is described. The mobile device includes a housing having a pistol grip portion. A display is coupled to the housing such that the display is viewable by a user of the mobile device when the pistol grip portion is held in a hand of the user. A trigger-like control switch is located on the pistol grip portion of the mobile device. A pointing device is located on the trigger-like control switch such that the pointing device is accessible to an index finger of a hand of the user when the pistol grip portion is held in the hand of the user. The pointing device controls at least one function of the mobile device.
