Bicycle Hanger with Rotating Arms and Pivot Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bicycle positioning devices lack adjustability and stability, particularly for professional bikes like road and mountain bikes, due to fixed configurations and inadequate pivot mechanisms, limiting their application and usability across different types of bicycles.
Innovation Solution
A bicycle hanger with a base and two supporting units, each featuring a rotatably connected supporting arm, positioning notches, a positioning member, and an elastic member, allowing for angular adjustment and enhanced stability through a pivot mechanism and anti-slip washer, enabling secure and versatile bike support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed configuration positioning device is used, then the structure is simple, but it can only lean against specific position of bicycle and cannot be used for other types of bikes
Solution Approach 1:
The patent applies the dynamics principle by making the supporting arm rotatable relative to the base through a pivot member, allowing the arm to be adjusted to different angles and positions. This dynamic adjustment capability enables the positioning device to adapt to various bicycle types and frame geometries, resolving the contradiction between adaptability and structural simplicity.
2Adaptability or versatility
If a foldable rack with specific configuration is used, then it can be compact when folded, but it still has the same shortcoming of fixed configuration when unfolded
Solution Approach 1:
The patent implements a rotatable supporting arm connected to the base via a pivot member, enabling continuous angular adjustment rather than fixed configurations. This dynamic structure allows easy operation and adaptation to different bicycle types, resolving the contradiction between configuration flexibility and ease of operation.
3Adaptability or versatility
If a tire-holding rack is used, then it can be applied to most bicycles, but its positioning effect is not good and bicycle handle and frame are prone to be unstable
Solution Approach 1:
The patent uses a rotatable supporting arm with pivot member that can be positioned at multiple angles to properly support the bicycle frame and handle area, providing stable positioning. The arm can be adjusted to contact the bicycle at optimal points, resolving the contradiction between broad applicability and stability.
Solution Approach 2:
The patent replaces the tire-holding mechanism with a frame-supporting arm that contacts the bicycle frame and handle area. This mechanical substitution provides superior stability by supporting the rigid frame structure rather than relying on the tire, while maintaining applicability to most bicycle types through angular adjustment.
4Adaptability or versatility
If devices lack proper pivot mechanism, then the structure is simpler, but they cannot be widely applied and easily adjusted
Solution Approach 1:
The patent introduces a pivot member that enables the supporting arm to rotate relative to the base. This simple yet effective pivot mechanism provides the necessary adaptability and ease of adjustment without excessive complexity, resolving the contradiction between adaptability and structural simplicity.
