Bicycle Accessory Mounting Bracket With Stepless Rotational Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current bicycle accessory mounting brackets lack the ability to fine-adjust the position of installed accessories, such as speedometers, limiting user convenience due to fixed orientations.
Innovation Solution
A bicycle accessory mounting bracket design featuring a first member, a second member, and a plug member with sliding slots and actuating mechanisms, allowing for rotational adjustment of the accessory's position relative to the bicycle connector, enabling precise positioning and locking of accessories.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a simple fixed mounting bracket is used, then the device complexity is low, but the adaptability is poor because the accessory position cannot be adjusted
Solution Approach 1:
The mounting bracket is divided into multiple functional components: a first member with a first connecting pillar, a second member with a second connecting pillar, and a plug member with abutting members. This segmentation allows each component to perform a specific function (connection, rotation, locking) while maintaining overall simplicity and enabling the desired position adjustability.
Solution Approach 2:
The mounting bracket transitions from a static fixed structure to a dynamic adjustable structure by allowing the first connecting pillar to rotate relative to the second connecting pillar through the through hole, while the plug member provides dynamic locking capability to maintain positions during use.
2Ease of operation
If a fixed mounting bracket is used, then the manufacturing precision requirements are low, but the ease of operation is poor because the accessory position cannot be fine-adjusted
Solution Approach 1:
The plug member acts as an intermediary component that simplifies the adjustment operation. By pushing the plug member, users can easily lock or unlock the rotation without requiring precise manual alignment, while the sliding slot and through hole provide the necessary guidance and constraint for smooth operation.
3Adaptability or versatility
If a rotatable connection is added to enable position adjustment, then the adaptability improves, but the reliability may worsen due to potential loosening during rotation
Solution Approach 1:
The abutting members are designed to abut against the inner surfaces of the sliding slot to prevent unwanted rotation or loosening during use. This preliminary constraint mechanism ensures that once the accessory is positioned and locked, it remains stable and secure without drifting during normal operation.

AI summary
A bicycle accessory mounting bracket includes a first member, a second member and a plug member. The first member has a first connecting pillar with a first sliding slot. The second member has a second connecting pillar. The plug member is inserted into the first and second connecting pillars inserted into each other through the first sliding slot and the through hole of the second connecting pillar. The plug member includes a shell, an actuating member and two abutting members. The actuating member has a wide portion and a concave portion. In the first position, the wide portion is located between the penetration holes, and the abutting members are pushed by the wide portion to enter the perforation holes. When in the second position, the concave portion is located between the penetration holes, the abutting members enter the concave portion, and the first and second connecting pillars can rotate relatively.
