Bicycle Phone Mount With Rotational Locking and Secure Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing holding devices for attaching mobile devices to two-wheelers are cumbersome to mount and dismount due to the need for manual manipulation of locking mechanisms.
Innovation Solution
A holding device with multiple rotational positions, including a third position that secures the adapters together, allowing for easier mounting and dismounting by rotating the adapters relative to each other, eliminating the need for manual unlocking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a bayonet fitting with protrusion and hole is used to lock adapters, then the holding device achieves secure locking, but the dismounting process becomes cumbersome requiring manual manipulation
Solution Approach 1:
The locking mechanism transitions from a static protrusion-hole engagement to a dynamic spring-loaded system. The spring element enables automatic engagement and disengagement through rotational movement, transforming the manual manipulation process into a simple rotational action that dynamically adjusts the locking state.
Solution Approach 2:
The spring element provides self-service by automatically maintaining the locked state through continuous contact force. When the adapter is rotated into the locked position, the spring automatically engages the protrusion with the hole without requiring manual intervention to maintain the locked state.
2Reliability
If multiple rotational positions are provided including a third securing position, then the holding device prevents accidental release, but the device complexity increases
Solution Approach 1:
The rotational movement is segmented into distinct positions (first, second, and third positions) with the third position providing additional security. This segmentation allows the system to offer multiple functional states within a single continuous rotational mechanism, preventing accidental release while maintaining operational simplicity.
Solution Approach 2:
The third rotational position serves as a preliminary securing action before final locking. By requiring the adapter to pass through the third position during engagement, the system ensures proper alignment and intentional operation, preventing accidental release while the spring mechanism handles the complexity of maintaining all positions.

AI summary
A mounting device for attaching a mobile device, such as a smartphone (2), to a two-wheeled vehicle, comprising a first mounting device (1) for attaching the mobile device to the mounting device and a second mounting device (3) for attaching the mounting device to the two-wheeled vehicle, wherein the first mounting device has a first adapter (10) and the second mounting device has a second adapter (29), wherein the first adapter (10) is connectable to the second adapter (29) for attaching the mobile device to the two-wheeled vehicle, wherein the adapters (10, 29) are rotated from at least a first rotational position to at least a second rotational position relative to each other about a rotational axis (38) for the connection of the adapters (10, 29), wherein the mounting device is in a release state in the at least one first rotational position of the adapters (10, 29) in which the adapters (10,29) are detachable from one another by a linear movement, and wherein the holding device is in a locking state in the at least one second rotational position of the adapters (10, 29) in which the adapters (10, 29) are not detachable from one another by a linear movement, wherein the holding device is configured such that at least one third rotational position is provided between the at least one first rotational position and the at least one second rotational position, in which parts of the first and/or the second fastening device (1, 3) interlock with one another, so that the first adapter (10) can only be moved from the at least one third rotational position relative to the second adapter (29) into the at least one first and/or into the at least one second rotational position against resistance.
