Solution Overview

Problem

Portable devices face a dilemma in reducing size and weight while accommodating multiple functions, as adding individual buttons for each function results in small, easily damaged buttons and increased size, compromising mobility and manoeuvrability.

Innovation Solution

A portable device with a multi-purpose input sensor, such as a switch button, that analyzes manipulation patterns and duration information to select and trigger different functional modes, such as photo-capturing and video-recording, using a control module, allowing multiple functions to be performed with a single button.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If individual buttons are added for each function, then the device can perform multiple functions, but the device size increases and buttons become small and easily damaged

Engineering Contradiction:
Improvefunctional modesVSAvoiddevice size
Core Design Contradiction:
Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The patent applies multi-functionality by enabling a single button to perform multiple functions through different manipulation patterns. The button can trigger photo-capturing mode with a first manipulation pattern, video-recording mode with a second manipulation pattern, and other functions with additional patterns. This eliminates the need for separate buttons for each function, maintaining compact device size while providing diverse functional capabilities.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent applies dynamics by making the button's function variable based on manipulation characteristics. The control module analyzes manipulation patterns including pressing duration, pressing force, and manipulation sequence to dynamically determine which function to execute. This transforms a static single-function button into a dynamic multi-function input device.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If individual buttons are added for each function, then the device can perform multiple functions, but the buttons become small and hard to locate

Engineering Contradiction:
Improvefunctional modesVSAvoidbutton accessibility
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

By consolidating multiple functions into one button, the patent ensures that the button maintains a standard, easily locatable size. The button's prominent position and familiar form factor make it simple for users to find and operate, while the system intelligently determines the appropriate function based on manipulation patterns.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent applies feedback by providing visual or haptic feedback to help users understand which manipulation pattern is being detected. The system can display icons indicating available functions or provide tactile feedback to confirm successful manipulation, making it easier for users to operate the single multi-functional button accurately.

Inventive Principle:
Principle #23Feedback

3Adaptability or versatility

If individual buttons are added for each function, then the device can perform multiple functions, but the device weight increases

Engineering Contradiction:
Improvefunctional modesVSAvoiddevice weight
Core Design Contradiction:
Adaptability or versatilityVSWeight of moving object

Solution Approach 1:

The patent significantly reduces device weight by eliminating the need for multiple physical buttons. Instead of adding separate buttons for photo-capturing, video-recording, and other functions, the system uses a single button with software-based function differentiation through manipulation pattern recognition. This removes unnecessary physical components while maintaining full functional capability.

Inventive Principle:
Principle #6Universality (Multi-functionality)

4Adaptability or versatility

If individual buttons are added for each function, then the device can perform multiple functions, but the device complexity increases

Engineering Contradiction:
Improvefunctional modesVSAvoidbutton configuration
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent simplifies device complexity by using a single button configuration instead of multiple buttons. While the control software becomes more sophisticated to handle different manipulation patterns, the physical structure remains simple with only one button component. This reduces assembly complexity, manufacturing complexity, and user interface complexity compared to having separate buttons for each function.

Inventive Principle:
Principle #6Universality (Multi-functionality)
