Solution Overview
Problem
Users, especially older individuals, find it difficult to operate complex image display apparatuses due to the need to press specific buttons in a predetermined order to select functions like image change, enlargement, or reduction, which can be confusing and challenging.
Innovation Solution
An input device with a flexible base member equipped with bend and nip detectors, allowing users to perform these functions by bending or nipping the base member, which sends signals to control the image display, simplifying the operation process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple buttons are provided for different functions, then the functionality of the device is improved, but the ease of operation deteriorates due to the complexity of remembering button combinations and sequences
Solution Approach 1:
A single flexible operation portion serves multiple functions by detecting different bending patterns and nipping positions. The flexible base member with embedded detectors can identify various user intentions (image change, enlargement, reduction) through different bending directions and nipping locations, eliminating the need for multiple separate buttons while maintaining full functionality.
Solution Approach 2:
The operation portion detects changes in bending direction, bending amount, and nipping position to differentiate between various functions. By monitoring these physical parameters of the flexible base member's deformation, the system can distinguish between different user intentions and execute corresponding functions without requiring multiple buttons.
2Adaptability or versatility
If multiple detectors are integrated into the flexible base member, then the functionality is improved, but the device complexity increases
Solution Approach 1:
Multiple detectors (first detector for bending, second detector for nipping) are integrated into a single flexible base member structure. This merging of detection functions into one component achieves multiple functionalities while managing complexity through unified design rather than separate components.
Solution Approach 2:
The flexible base member serves as both the structural element and the sensing element, integrating multiple detection capabilities (bending detection, nipping detection) into a single multi-functional component that simplifies the overall device architecture.
