Elastic Holder Band for Straddled Vehicle Light Control Unit Vibration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing straddled vehicle lighting systems face challenges in vibration isolation and stability of the light control unit, and water ingress into connectors, which limits layout flexibility and increases arrangement space requirements.
Innovation Solution
A straddled vehicle design featuring a light control unit supported by an elastic holder with a band that wraps around the unit, providing improved vibration isolation and stable holding, while the band's downward orientation and waterproofing prevent water from entering the connectors, maintaining layout flexibility and reducing arrangement space expansion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the light control unit is rigidly fixed to the stay, then the holding stability is improved, but the vibration isolation becomes low
Solution Approach 1:
The patent introduces a holder as an intermediary component between the light control unit and the stay. This holder serves as a mediator that provides both stable holding through its attachment mechanism and vibration isolation through its elastic material composition, resolving the contradiction between rigid fixation and vibration damping.
Solution Approach 2:
The holder is made of elastic material, which changes the mechanical parameters of the connection system. The elastic material allows the holder to deform under vibration, providing vibration isolation while maintaining stable holding through its elastic recovery properties, thus resolving the contradiction between rigidity and vibration damping.
2Object-affected harmful factors
If the light control unit is arranged in a place where water is difficult to enter, then water intrusion prevention is improved, but the degree of freedom in layout is reduced
Solution Approach 1:
The patent extracts the waterproofing function from the structural design and implements it through a separate waterproof cover component. This allows the light control unit to be positioned for optimal layout flexibility while the waterproof cover provides water intrusion prevention, resolving the contradiction between positioning constraints and layout freedom.
3Object-affected harmful factors
If a waterproof structure for the connector is provided, then water intrusion prevention is improved, but the arrangement space is expanded
Solution Approach 1:
The patent employs a waterproof cover that acts as a flexible barrier to protect the connector from water intrusion. This thin-film approach provides effective waterproofing without requiring bulky waterproof structures, thus preventing water intrusion while minimizing the expansion of arrangement space.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enhances vibration isolation and stability of the light control unit, prevents water ingress into connectors, and maintains layout flexibility without increasing arrangement space, thereby improving overall performance and design efficiency.
Implementation Method 1
a holder (36) that holds the light control unit (35) and is made of elastic material
Implementation Method 2
The band is wound around the light control unit. The band extends from above to below the light control unit. The band overlaps the connector as seen in a vehicle front view
