Rotatable Adapter for Slide-In Holding Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing adapters for detachably fastening portable devices to holding devices require specialized adapters for rotational movement, limiting their application to only specific holding devices designed for rotational fastening, whereas most are designed for straight-line shifting, restricting versatility and broad application.
Innovation Solution
An adapter with outwardly extending projections and a rotatable guide disk that can be locked or released by 90°, allowing secure fastening to holding devices originally designed for straight-line movement, using plug-in areas on the guide disk for engagement with guide walls of the holding device, enabling rotational fastening without the need for specialized devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an adapter is designed for rotational fastening to holding devices, then secure rotational attachment is achieved, but the adapter can only be used with specialized holding devices designed for rotational movement, limiting versatility
Solution Approach 1:
The adapter combines both rotational and linear fastening capabilities in a single device. The guide disk with plug-in areas enables rotational attachment to specialized holding devices, while the same plug-in areas also accept guide walls of universal slide-in holding devices. This multi-functional design allows one adapter to work with multiple types of holding devices, resolving the contradiction between secure rotational attachment and versatility.
2Reliability
If a separate specialized adapter is required for each type of holding device, then optimal fastening for each device type is achieved, but device complexity and number of components increases
Solution Approach 1:
The patent designs a single universal adapter that can interface with both specialized rotational holding devices and universal slide-in holding devices. The guide disk structure with opposing plug-in areas serves dual purposes: enabling rotational fastening when paired with specialized devices and linear fastening when paired with universal devices. This eliminates the need for multiple specialized adapters, reducing component variety while maintaining optimal fastening performance for each device type.
3Ease of manufacture
If holding devices are designed for straight-line shifting movement, then simple structure and ease of manufacture are achieved, but they cannot accommodate rotational fastening without specialized adapters
Solution Approach 1:
The adapter acts as an intermediary component that bridges the compatibility gap between simple slide-in holding devices and rotational fastening requirements. The guide disk with plug-in areas serves as the mediating structure that can interface with the simple guide walls of slide-in devices while enabling rotational movement. This allows existing simple holding devices to work with rotational adapters without requiring redesign of the holding devices themselves.

AI summary
An adapter for releasably fastening a portable/compact unit or object to a holding device. The adapter comprises a base plate and two projections projecting away from one another in opposite directions and at a spacing from the base plate. The base plate has means for attaching the adapter to the unit or object or attached fixedly thereto or is configured in one piece with it. A guide disc is mounted on the base plate, is parallel to said base plate and can be rotated at least to a limited extent between at least one released position and at least one locked position. The guide disc has a middle opening, into which the two projections extend. The opening comprises two plug-in regions into which a holding device suitable for interaction with the adapter can be plugged in at least partially when the guide disc is situated in a released position.
