Solution Overview
Problem
Sound deadening tapes used in automobile wiring experience low abrasion resistance and layer separation issues, leading to reduced work efficiency and performance.
Innovation Solution
A binding tape with a substrate layer comprising a non-woven fabric featuring at least two types of fused sections with different shapes or sizes, thermally formed by heat embossing, which enhances abrasion resistance and suppresses layer separation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a substrate layer comprising non-woven fabric is used for sound deadening, then tapping noises and scratching noises are attenuated, but layer separation occurs when the tape is rewound or drawn from a tape roll
Solution Approach 1:
The fused sections are divided into at least two types with different shapes (e.g., circular and linear) or different sizes, creating a segmented bonding pattern that prevents uniform layer separation while maintaining sound deadening properties
Solution Approach 2:
Different regions of the substrate layer have different fusion characteristics through the use of multiple fused section types, creating localized bonding strengths that collectively prevent layer separation while preserving overall noise attenuation capability
2Reliability
If a substrate layer with fused sections is used to suppress layer separation, then layer separation is reduced, but abrasion resistance decreases
Solution Approach 1:
The fused sections are segmented into multiple types with different shapes and sizes distributed across the substrate layer, creating a balanced structure that provides both layer separation suppression and adequate abrasion resistance through diversified bonding points
Solution Approach 2:
The fusion parameters (shape, size, distribution) of the fused sections are optimized to achieve the right balance between preventing layer separation and maintaining abrasion resistance, rather than using a single fusion pattern
3Stability of the object's composition
If binding tape is used in concealed locations subject to vibration, then wires are bound together, but tapping noises and scratching noises are generated
Solution Approach 1:
The binding tape uses a composite structure combining non-woven fabric substrate with adhesive layer and multiple fused sections, creating a material that provides both wire bundling stability and noise attenuation through its layered composition
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 binding tape achieves improved sound deadening properties, increased abrasion resistance, and reduced layer separation, ensuring effective noise attenuation and prolonged usage.
Implementation Method 1
the non-woven fabric acts as a cushioning material and it is possible to attenuate tapping noises and scratching noises
Implementation Method 2
the fused sections are formed by thermally fusing fibers of the non-woven fabric by a heat embossing
