Rotatable Display Holder Structure for Vibration-Resistant Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic device holders, particularly those for vehicles like aircraft, are not adequately durable to withstand frequent use and vibrational loads, and often lack adaptability for various applications and vehicle types.
Innovation Solution
A device holder with a back plate and rotatable engaging members around its periphery, formed from durable materials like metal, which secures the device with a locking mechanism and allows for adjustable mounting configurations, including a rotatable mounting flange for orientation changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If plastic or interference fit materials are used for mounting structures, then ease of manufacture is improved, but reliability and durability under vibrational loads deteriorates
Solution Approach 1:
The mounting structure uses a composite construction combining a rigid back plate with flexible engaging members. The back plate provides structural strength to withstand vibrational loads, while the flexible engaging members provide interference fit retention. This composite approach resolves the contradiction by combining materials with different properties to achieve both manufacturability and reliability under vibration.
Solution Approach 2:
The mounting structure is divided into separate functional components: a back plate for structural support and mounting, and flexible engaging members for device retention. This segmentation allows each component to be optimized for its specific function - the back plate for strength and rigidity, and the engaging members for flexible retention - thereby achieving both ease of manufacture and reliability.
2Device complexity
If fixed mounting structures are used, then device complexity is reduced, but adaptability to different vehicles and applications deteriorates
Solution Approach 1:
The mounting structure incorporates a rotatable mounting flange that can be adjusted to different orientations and positions. This dynamic element allows the same basic structure to adapt to different mounting locations and angles on various vehicle types without requiring multiple specialized designs, thereby achieving adaptability while maintaining relatively simple device complexity.
Solution Approach 2:
The mounting structure is designed with universal features including a rotatable flange and adjustable engaging members that can accommodate different device sizes and mounting configurations. This multi-functionality allows a single design to serve multiple vehicle types and application scenarios, resolving the contradiction between simplicity and adaptability.
3Reliability
If permanent retention mechanisms are used, then reliability is improved, but ease of operation for device removal deteriorates
Solution Approach 1:
The engaging members are designed to be flexible and movable rather than fixed. They can deflect to allow easy insertion and removal of the display device, yet maintain reliable retention when the device is properly installed. This dynamic behavior resolves the contradiction by providing both secure retention and ease of operation through the same mechanism.

AI summary
In one example, an apparatus for holding a display device includes a back plate and a plurality of engaging members disposed around a periphery of the back plate. The back plate includes a rear face and a front face opposite the rear face. The plurality of engaging members extend from the back plate in a direction from the rear face to the front face to define an outer boundary of a retention space configured to accept the display device. The plurality of engaging members includes a rotatable engaging member configured to rotate between an engagement position and a disengagement position. The engagement position is configured to secure the display device within the retention space. The disengagement position is configured to allow removal of the display device from the retention space.
