Foldable Training Wheel Device With Telescopic Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional training wheel devices are inconvenient to assemble and disassemble, requiring users to remove and reattach the nut structure, which complicates the process.
Innovation Solution
A foldable training wheel device comprising an outer tube, an inner tube, and a positioning module with a restoring unit, allowing the inner tube to be rotated and moved between a riding position and a folded position, eliminating the need for disassembly by using a positioning unit with recesses and an engagement unit to switch between positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a nut structure is used to mount the training wheel on the rear wheel, then the training wheel can be securely attached, but the assembly and disassembly process becomes complex and inconvenient
Solution Approach 1:
The mounting structure is divided into separate components: a mounting bracket fixed to the bicycle frame, and a training wheel assembly with a simplified connection mechanism. This segmentation allows the training wheel to be easily detached from the bracket without complex nut fastening, resolving the contradiction between secure attachment and ease of assembly/disassembly.
Solution Approach 2:
The complex nut structure is extracted and replaced with a simpler bracket-based mounting system. The training wheel assembly can be quickly removed from the bracket by simply releasing a latch or release mechanism, eliminating the need for tool-based nut fastening while maintaining secure attachment during use.
2Stability of the object's composition
If the training wheel is designed as a fixed structure, then it provides stable support, but it cannot accommodate different user needs for folding or compact storage
Solution Approach 1:
The training wheel assembly incorporates movable joints and telescopic tubes that allow it to transition between extended (riding) and folded (storage) configurations. The inner tube can rotate and move up and down within the outer tube, enabling the structure to adapt between providing stable support during riding and compact folding for storage, thus resolving the contradiction between stability and adaptability.
Solution Approach 2:
The inner tube is nested within the outer tube, with the inner tube capable of rotating and moving vertically. This nested configuration allows the training wheel to be folded into a compact form for storage while maintaining its structural integrity and stability when extended for riding, accommodating different user needs without compromising either stability or adaptability.

AI summary
A foldable training wheel device has an outer tube, an inner tube, a positioning module, and a training wheel. The inner tube is inserted in the outer tube, is rotatable in the outer tube, is up and down moveable in the outer tube, and has a riding position and a folded position. The positioning module is mounted on the outer tube and the inner tube to position the inner tube on one of the riding position and the folded position relative to the outer tube. The training wheel is mounted on a bottom of the inner tube. Therefore, the foldable training wheel device is provided with two using modes for users.
