Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing load carriers for bicycles attached to camping trailers often result in the bicycle touching the towing vehicle due to a fixed pivoting angle, leading to potential damage during transport.
Innovation Solution
A load carrier design with a base frame and platform that can pivot, featuring a connecting element with adjustable attachment points and a flexible area, allowing for variable pivoting angles to match the distance between the towing vehicle and camping trailer, preventing contact and damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a fixed pivoting angle is used in the load carrier, then the structure is simple and manufacturing is easy, but the bicycle may touch the towing vehicle causing damage
Solution Approach 1:
The patent applies the dynamics principle by making the pivoting angle adjustable rather than fixed. The connecting element allows the platform to pivot at variable angles, enabling the system to adapt dynamically to different distances between the towing vehicle and camping trailer. This resolves the contradiction by sacrificing manufacturing simplicity for the ability to prevent damage through angle adjustment.
Solution Approach 2:
The patent implements parameter changes by allowing the pivoting angle to be varied within a range. The connecting element with its specific geometric configuration enables the platform to achieve different angular positions, transforming the fixed parameter into a variable one. This allows optimization of the pivoting angle to prevent contact between the bicycle and towing vehicle while maintaining structural integrity.
2Object-affected harmful factors
If the pivoting angle is increased to avoid contact with the towing vehicle, then damage is prevented, but the platform becomes less stable
Solution Approach 1:
The patent optimizes the pivoting angle parameter within a specific range rather than maximizing it. The connecting element's geometric parameters are designed to provide sufficient angle variation for damage prevention while maintaining platform stability. This balanced parameter selection resolves the contradiction between damage prevention and stability.
Solution Approach 2:
The system allows dynamic adjustment of the pivoting angle based on operating conditions. The platform can pivot to an optimized angle that prevents contact with the towing vehicle while maintaining adequate stability for bicycle transport. This dynamic optimization resolves the contradiction by adapting the angle to specific operational requirements.
3Adaptability or versatility
If adjustable attachment points are implemented, then the pivoting angle can be adapted to individual distances, but the device complexity increases
Solution Approach 1:
The patent achieves adaptability through parameter changes in the connecting element's geometric configuration rather than through complex mechanical adjustments. The specific dimensions and arrangement of the connecting element allow the pivoting angle to be optimized for different distances while maintaining a relatively simple structure. This resolves the contradiction by using parameter optimization instead of complex adjustable mechanisms.
