Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing handheld electronic devices with moving form factors, such as slider and flip phones, are limited in their input interfaces and operational modes due to their fixed open and closed positions, which do not adequately support the evolving software and uses of these devices.
Innovation Solution
A handheld electronic device featuring a slide-and-twist mechanism that allows for multiple device positions by sliding and rotating body parts, exposing different input devices such as keyboards, touchpads, and touchscreens, enabling various operational modes and user interfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed open and closed position mechanism is used, then the device structure is simple, but the adaptability to different software and uses is limited
Solution Approach 1:
The patent applies the dynamics principle by transforming the static fixed-position mechanism into a dynamic multi-position mechanism. The slide-and-twist mechanism allows the device to transition between multiple configurations (closed, open with keyboard exposed, open with touchpad exposed), enabling the device structure to adapt dynamically to different software applications and usage scenarios, thereby resolving the contradiction between structural simplicity and adaptability.
Solution Approach 2:
The patent applies segmentation by dividing the device into separable components (first body and second body) that can move independently relative to each other. This segmentation allows different input devices (keyboard, touchpad) to be positioned on different bodies, enabling selective exposure of input devices based on the required function, thus improving adaptability without requiring complete structural redesign.
2Adaptability or versatility
If multiple input devices are provided, then the versatility of the device is improved, but the device complexity increases
Solution Approach 1:
The patent applies the universality principle by designing a single mechanical mechanism (slide-and-twist) that serves multiple functions: it controls the exposure of different input devices (keyboard, touchpad), manages device form factor transformations, and adapts to various software modes. This multi-functional approach provides input interface versatility without proportionally increasing overall device complexity.
Solution Approach 2:
The patent applies self-service by implementing automatic detection and mode switching based on device position. The controller automatically detects which input device is exposed and switches the operational mode accordingly, eliminating the need for manual configuration and reducing the perceived complexity for users while maintaining versatile input capabilities.
3Ease of manufacture
If the device structure is simplified, then the ease of manufacture is improved, but the ability to support evolving software is reduced
Solution Approach 1:
The patent applies dynamics by creating a mechanism that can adapt its configuration to support evolving software requirements. The slide-and-twist mechanism provides a scalable framework that can accommodate different input device arrangements and software modes without requiring complete redesign, thus maintaining ease of manufacture while supporting software evolution.
