Bicycle Trainer Fastening Device with Interchangeable Apertures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bicycle trainers have a limited scope of applicability due to their inability to accommodate bicycles with different axle diameters, as they typically feature a hollow tube with a single aperture that does not fit various types of bicycles.
Innovation Solution
A bicycle trainer with a hollow tube having two replaceable fastening members at opposite ends, each with adjustable openings to fit different shaft diameters, allowing the device to adapt to various axle diameters and lengths, thereby increasing its applicability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a hollow tube with a single aperture is used in the bicycle trainer, then the structure is simple and easy to manufacture, but the adaptability to different bicycle axle diameters is limited
Solution Approach 1:
The fastening device is segmented into multiple interchangeable fastening members, each with different aperture sizes. Instead of having a single fixed aperture in the hollow tube, the patent divides the fastening function into separate components (first fastening member with first aperture, second fastening member with second aperture) that can be selected and swapped based on the bicycle axle diameter, thereby achieving adaptability without complicating the overall structure
Solution Approach 2:
The hollow tube is designed to serve multiple functions by accommodating different fastening members. The same hollow tube structure can work with various bicycle types (mountain bikes, road bikes) by simply changing the fastening member, making the overall device universal and multi-functional without requiring multiple different hollow tube designs
2Adaptability or versatility
If a single aperture hollow tube is used, then the device is easy to operate, but the scope of applicability to different bicycle types is limited
Solution Approach 1:
Different fastening members with different aperture sizes are prepared in advance and can be selected based on the bicycle type before installation. The user measures the axle diameter, selects the appropriate pre-prepared fastening member, and installs it on the hollow tube. This preliminary preparation and selection process maintains ease of operation while expanding the scope of applicability to different bicycle types

AI summary
A bicycle trainer fastening device, disposed on a bicycle trainer, includes a hollow tube, a first fastening member and a second fastening member. The hollow tube includes a first assembly portion and a second assembly portion at two opposite ends thereof. The first fastening member is disposed correspondingly to the first assembly portion, and includes a first through opening correspondingly in communication with the hollow tube and having an aperture corresponding to an inserting shaft of a bicycle. The second fastening member is disposed correspondingly to the second assembly portion, and includes a second through opening correspondingly in communication with the hollow tube and an aperture corresponding to the inserting shaft. By selecting the first through opening and the second through opening corresponding to the shaft diameter of the inserting shaft and replacing the first fastening member and the second fastening member, the scope of applicability can be maximized.
