Motorcycle Case Assembly with Removable Anchoring Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motorcycle side case assemblies fail to balance aesthetics, aerodynamics, and functionality, as they often require custom frame modifications, are difficult to mount and remove, and do not securely anchor heavy or bulky cases, leading to aerodynamic issues and increased weight when not in use.
Innovation Solution
A removable supporting structure that can be easily attached and detached from the motorcycle, allowing for different configurations based on case size and type, ensuring secure anchoring without compromising the motorcycle's appearance or aerodynamics, and enabling quick mounting and removal of cases.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If large side cases or bags are mounted to the motor cycle, then enough place for storing luggage is provided, but the aerodynamic of the motor cycle and the balance are negatively affected
Solution Approach 1:
The case assembly is divided into separate modular cases that can be independently mounted or removed. Each case is designed as an independent unit that can be attached to standardized anchoring parts, allowing the storage capacity to be segmented into manageable portions that have reduced negative impact on aerodynamics compared to a single large case.
Solution Approach 2:
The case assembly system is designed to be dynamic rather than fixed. Cases can be easily mounted and removed from the motor cycle, allowing the aerodynamic characteristics to be optimized by removing cases when not needed. The anchoring parts are designed to accommodate this dynamic configuration without compromising structural integrity.
2Strength
If the main frame of the motor cycle is designed ad hoc to support side bags, then heavy or bulky cases can be mounted, but the overall look and aerodynamic are negatively influenced when cases are removed, and the weight is increased
Solution Approach 1:
The support system is segmented into separate anchoring parts that are distinct from the main frame structure. These anchoring parts can be attached to or integrated with the frame but are designed as separate components that provide the necessary support strength without requiring the entire main frame to be redesigned with excessive material.
Solution Approach 2:
The anchoring parts are designed with universal functionality to support various case sizes and types. Rather than designing custom frame structures for specific case configurations, the universal anchoring parts can accommodate different case arrangements, reducing the need for specialized heavy frame modifications.
3Reliability
If anchoring parts of the main frame extend away from the motor cycle to support cases, then adequate anchoring and support is provided, but the overall look and aerodynamic are negatively influenced when cases are removed
Solution Approach 1:
The anchoring function is extracted from the main frame structure and implemented as separate, removable anchoring parts. This allows the anchoring capability to be taken out only when needed, rather than having permanent extensions that affect appearance and aerodynamics continuously. The anchoring parts can be removed or reconfigured when cases are not in use.
Solution Approach 2:
The anchoring system transitions from a static, fixed configuration to a dynamic system where anchoring parts can be adjusted or removed based on usage requirements. This dynamic capability allows the motor cycle to maintain its aesthetic appearance and aerodynamic characteristics when cases are not mounted, while still providing reliable anchoring when needed.
4Strength
If heavy metals such as high tensile steel are used for forming anchoring parts, then adequate support for heavy or bulky cases is provided, but the overall weight of the motor cycle is unduly increased
Solution Approach 1:
The material parameters of the anchoring parts are optimized to achieve the necessary strength with minimal weight. Rather than using heavy metals universally, the anchoring parts are designed with carefully selected material properties and cross-sectional dimensions that provide adequate strength only where and when needed, reducing overall weight while maintaining anchoring capability.
5Reliability
If fitting cases or bags to the anchoring parts is made secure, then cases are reliably fixed, but the mounting and removal process becomes difficult, troublesome and annoying
Solution Approach 1:
The fixing mechanism is segmented into simple, modular components that interface between the case and anchoring parts. This segmentation allows for straightforward attachment and detachment operations while maintaining secure fixation when mounted. The modular nature of the connection system enables easy engagement and disengagement without complex procedures.
Solution Approach 2:
The case assembly system is designed to be self-servicing, allowing users to easily mount and remove cases without requiring special tools or complex procedures. The anchoring parts and case interfaces are designed to work together in a user-friendly manner, providing reliable fixation that can be easily engaged and disengaged by the end user.
