Floor Silencer With Foldable Grooves for Flat Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional floor silencers with integrated sound insulation and bulk materials have complex three-dimensional shapes, leading to low transport efficiency and poor workability during assembly, as they are not easily foldable or transportable in a flat state.
Innovation Solution
A floor silencer with a band-like concave portion that allows for folding along its thickness direction, enabling flat transportation and easy assembly, while maintaining sound insulation and cushioning properties by integrating sound insulation material with the bulk material.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the floor silencer is made with a complex three-dimensional shape to follow the floor panel, then it achieves sufficient sound insulation and cushioning properties, but transport efficiency deteriorates
Solution Approach 1:
The floor silencer is divided into multiple regions by groove portions that extend in the longitudinal direction. These groove portions create segmented sections that can be folded along transverse lines, allowing the complex three-dimensional shape to be collapsed into a flat transport state while maintaining the functional regions for sound insulation and cushioning
Solution Approach 2:
The invention utilizes folding along transverse lines to transform the floor silencer between three-dimensional operational shape and two-dimensional flat transport shape. The groove portions enable this dimensional transformation by providing structural guidance for folding while preserving the sound insulation functionality in both states
2Reliability
If the floor silencer is made with a complex three-dimensional shape, then it provides sufficient cushioning and sound insulation, but workability during assembly deteriorates
Solution Approach 1:
The floor silencer is segmented by groove portions into multiple sections that can be independently folded and positioned. This segmentation allows workers to assemble the floor silencer by simple folding operations along the grooves, significantly improving workability while maintaining the complex three-dimensional shape needed for cushioning and sound insulation
Solution Approach 2:
The groove portions are pre-formed during manufacturing to indicate the folding lines. This preliminary action of creating the groove structure in advance enables workers to easily understand and execute the assembly process by simply folding along the pre-defined grooves, improving assembly workability without compromising the final three-dimensional shape
3Quantity of substance
If the floor silencer is made flat for efficient transport, then transport efficiency improves, but it cannot achieve the complex shape needed for sound insulation and cushioning
Solution Approach 1:
The floor silencer is designed with dynamic shape transformation capability through the groove portions. It can transition from a flat two-dimensional state during transport to a complex three-dimensional state during operation. The grooves act as hinges that enable this dynamic shape change, allowing the same component to satisfy both transport efficiency and sound insulation requirements at different stages
Solution Approach 2:
The floor silencer can be folded into a compact flat state that nests efficiently during transport. The groove portions allow the material to be folded back on itself, creating a nested configuration that maximizes transport efficiency while preserving the ability to unfold into the functional three-dimensional shape at the installation site
