Fluid Container Premounted Clamping Strap Exterior Fixation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluid containers for motor vehicles, such as fuel tanks, face challenges in maintaining interior volume while ensuring stable attachment and easy handling of clamping straps, as grooves or protrusions required for strap fixation reduce interior space and complicate installation, especially when pump modules are involved.
Innovation Solution
The fluid container features premounted clamping straps without additional fixing means, utilizing protrusions molded into the container that engage with correspondingly formed openings in the straps, allowing for secure attachment without reducing interior volume and enabling easy handling during assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If grooves are inserted in the container floor to support clamping straps, then the stability and load relief of the container is improved, but the interior volume of the container is reduced
Solution Approach 1:
The invention extracts the clamping strap fixation function from the container interior by moving it to the container exterior. The clamping straps are attached to the outer surface of the container wall, eliminating the need for grooves or protrusions in the container floor, thus preserving the full interior volume while maintaining structural stability.
Solution Approach 2:
The invention transitions the clamping strap attachment from a two-dimensional floor-based system to a three-dimensional surface-based system. Instead of inserting straps into floor grooves, the straps are attached to the external container surface, utilizing the container's outer surface area for fixation without compromising internal space.
2Ease of operation
If clamping straps are premounted on the fluid container, then the ease of handling during assembly is improved, but additional fixing means or structural modifications are required
Solution Approach 1:
The invention merges the clamping strap and container into a single integrated unit by premounting the straps directly onto the container during manufacturing. The straps are attached to the container's outer surface using simple attachment means, creating a combined assembly that simplifies handling and installation without requiring complex additional fixing structures.
3Reliability
If grooves or protrusions are added to the container contour for strap fixation, then the attachment stability is improved, but the interior space available for pump modules is reduced
Solution Approach 1:
The invention extracts the attachment function from the container's interior structure by placing clamping straps on the exterior surface. This eliminates the need for grooves or protrusions that would otherwise intrude into the interior space, ensuring that the full volume is available for pump modules and fluid storage while maintaining reliable attachment through external strap fixation.
