Rotary Display Adjuster Assembly With Light and Ingress Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The integration of a rotary adjuster with rotary position detection on an electronic display with a transparent outer layer poses challenges due to the risk of foreign body intrusion, particularly liquids, and undesired light emission, which can damage the mounting and affect the functionality of the rotary adjuster and the display.
Innovation Solution
A surrounding wall-like protrusion is provided around the bearing means of the rotary adjuster, formed from opaque material with a circumferential air gap to prevent foreign body intrusion and light emission, while maintaining haptic feedback and allowing for optical projection through apertures, thereby protecting the internal components from contamination and ensuring effective light shielding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the rotary adjuster is mounted on the transparent layer without a surrounding wall, then the structure remains simple and light transmission is maintained, but foreign bodies can easily enter the rotary adjuster and cause damage
Solution Approach 1:
The transparent layer is segmented by introducing a surrounding wall that divides the space into an internal region (housing the rotary adjuster) and an external region. This segmentation creates a protective barrier without completely enclosing the structure, maintaining simplicity while preventing foreign body intrusion.
Solution Approach 2:
The surrounding wall acts as an intermediary element between the external environment and the rotary adjuster. It provides the necessary protection against foreign bodies while allowing light to pass through the transparent layer, thus mediating between protection requirements and optical functionality.
2Reliability
If a surrounding wall is added around the bearing means, then foreign body intrusion is prevented, but the device complexity increases
Solution Approach 1:
The surrounding wall is merged with the transparent layer structure, forming an integrated component rather than a separate addition. This combining approach provides protection while minimizing the increase in device complexity, as the wall becomes part of the existing transparent layer assembly.
3Object-generated harmful factors
If the transparent layer is made opaque to prevent light emission from below the rotary adjuster, then light isolation is improved, but the display visibility is reduced
Solution Approach 1:
The transparent layer is segmented into regions with different optical properties. The surrounding wall portion is made opaque to block light from the display area below the rotary adjuster, while the rest of the transparent layer remains transparent to maintain display visibility. This segmentation allows selective light control.
Solution Approach 2:
Different portions of the structure are assigned different optical qualities. The surrounding wall has opaque local quality to prevent light emission, while the main transparent layer maintains its transparent quality for display visibility. This local differentiation resolves the contradiction between light isolation and visibility.
