Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display technologies face challenges in providing haptic feedback while maintaining environmental sealing, particularly in applications requiring specialized sealing of components, such as aircraft control panels.
Innovation Solution
A display assembly with a double bezel design and an actuator assembly that moves the display module relative to the frame assembly, providing haptic feedback through tactile and vibrational means while maintaining an environmentally sealed interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single bezel design is used to provide haptic feedback, then the device complexity is reduced, but the environmental sealing and reliability deteriorate
Solution Approach 1:
The bezel structure is segmented into two distinct bezels: an outer bezel that provides environmental sealing and structural support, and an inner bezel that provides haptic feedback through actuator assembly. This segmentation allows each bezel to be optimized for its specific function, resolving the contradiction between simplicity and reliability.
Solution Approach 2:
The inner bezel is nested within the outer bezel, creating a concentric structure where the inner bezel is positioned inside the outer bezel. This nested configuration allows the haptic feedback mechanism to be contained within the sealed environment provided by the outer bezel, maintaining both functionality and sealing integrity.
2Adaptability or versatility
If the display module is made moveable to provide haptic feedback, then the haptic feedback capability is improved, but the environmental sealing deteriorates
Solution Approach 1:
The display module is designed to be moveable relative to the frame assembly through the actuator assembly, enabling dynamic haptic feedback responses. The moveable connection is integrated into the sealed structure, allowing the display to move while maintaining the environmental seal, thus resolving the contradiction between adaptability and sealing integrity.
3Adaptability or versatility
If the bezel-display interface is exposed to movement, then the haptic feedback is enhanced, but the interface degradation increases
Solution Approach 1:
The actuator assembly serves as an intermediary mechanism that couples the moveable display module to the fixed frame assembly. This intermediary structure enables haptic feedback movement while protecting the bezel-display interface from direct exposure to mechanical stress and environmental factors, reducing interface degradation.

AI summary
A display assembly includes a frame assembly, a display module having a display housing and a touch screen display disposed at least partially within the display housing such that the display module and touch screen display form an environmentally sealed exterior, and an actuator assembly. The display module is coupled to the frame assembly via the actuator assembly such that the display module is configured to provide haptic feedback to users via the touch screen display based on operation of the actuator assembly.
