Display Suspension via Segmented Casing for Tactile Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display and speaker suspension systems in portable electronic devices often result in poor 'feel' due to complex and inefficient mounting arrangements, which can compromise audio and tactile output quality.
Innovation Solution
A casing or cover design that suspends the display relative to a static portion of the device, utilizing flexible materials and shapes to allow the display to move, driven by motors or piezo-electric transducers, while maintaining structural integrity and providing tactile feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a complex mounting arrangement is used to suspend the display, then the structural integrity is maintained, but the audio and tactile output quality deteriorates
Solution Approach 1:
The mounting arrangement is divided into separate functional zones: rigid mounting regions at the periphery for structural support, and a flexible central region for display movement. This segmentation allows the display to move freely in the center while maintaining overall structural integrity through the rigid peripheral mounting points.
Solution Approach 2:
Different regions of the mounting arrangement have different mechanical properties - the peripheral regions are rigid to provide structural support, while the central region is flexible to allow display movement for audio/tactile output. This local differentiation of mechanical properties resolves the contradiction between structural integrity and output quality.
2Stability of the object's composition
If the display is rigidly mounted, then the structural stability is improved, but the tactile feedback quality deteriorates
Solution Approach 1:
The mounting structure is segmented into rigid peripheral portions that provide structural stability and a flexible central portion that enables display movement for tactile feedback. This segmentation allows simultaneous achievement of structural stability and tactile feedback quality.
Solution Approach 2:
The mounting arrangement transitions from a completely rigid structure to a dynamic structure with controlled flexibility in the central region. This allows the display to move dynamically for tactile feedback while the peripheral rigid portions maintain overall structural stability.
3Device complexity
If a simple mounting arrangement is used, then the device complexity is reduced, but the audio output quality deteriorates
Solution Approach 1:
The mounting arrangement merges structural support and display suspension functions into a single integrated structure. The rigid peripheral regions provide structural support while the flexible central region enables display movement for audio output, eliminating the need for separate complex suspension mechanisms.
Solution Approach 2:
The mounting arrangement serves multiple functions simultaneously: structural support through rigid peripheral regions, display suspension, and enabling tactile feedback through flexible central region movement. This multi-functionality reduces overall device complexity while maintaining audio output quality.
