Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional drying towels quickly reach saturation when used on large surfaces like vehicles, requiring frequent wringing and risking surface scratching due to fabric type or embedded particles.
Innovation Solution
A three-layer laminate construction comprising outer microfiber layers and an inner absorbent layer with features like openings or grooves, designed to enhance liquid absorption and retention while minimizing surface scratching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a conventional single-material towel is used for drying vehicle surfaces, then the towel structure is simple and easy to manufacture, but the liquid absorption capacity is insufficient and the towel quickly reaches saturation
Solution Approach 1:
The towel is constructed as a composite material system with an outer microfiber layer and an inner absorbent layer (chamois or highly absorbent fabric). The outer layer provides surface protection and initial liquid capture, while the inner layer provides bulk absorption capacity. This composite structure resolves the contradiction by combining materials with complementary properties to achieve high liquid absorption without excessive structural complexity.
Solution Approach 2:
The towel is divided into functionally distinct segments: an outer layer for surface interaction and a inner layer for bulk absorption. This segmentation allows each layer to be optimized for its specific function - the outer layer for protection and initial capture, the inner layer for sustained absorption - thereby increasing overall liquid absorption capacity while maintaining manageable structural complexity.
2Object-affected harmful factors
If a conventional fabric towel is used for drying, then the towel is easy to operate, but there is a risk of scratching the vehicle surface due to fabric texture or embedded particles
Solution Approach 1:
The outer layer of the towel is specifically designed with different properties than the inner layer - using soft, lint-free microfiber material that is gentle on vehicle surfaces. This local quality differentiation ensures that the surface-contacting portion of the towel provides protection against scratching, while the inner absorbent layer handles the bulk liquid absorption function.
Solution Approach 2:
The harmful abrasive properties are extracted from the surface-contacting portion of the towel by using a separate outer layer made of non-abrasive microfiber material. This extraction ensures that only the beneficial properties (softness, lint-free surface) remain at the vehicle-towel interface, while the inner layer handles the absorption function that would otherwise require abrasive materials.
3Quantity of substance
If a conventional towel with uniform structure is used, then the manufacturing process is simple, but the towel cannot effectively retain liquid across large surface areas
Solution Approach 1:
The towel uses composite materials with the inner layer made from highly absorbent material such as chamois or specially engineered absorbent fabric. This material selection provides superior liquid retention capacity through capillary action and bulk absorption, allowing the towel to effectively handle large surface areas without requiring complex manufacturing processes.
4Productivity
If the towel is made from a single material for simplicity, then the manufacturing is easier, but the towel reaches saturation quickly and requires frequent wringing
Solution Approach 1:
The towel is segmented into functional layers with the outer microfiber layer capturing liquid at the surface and the inner absorbent layer providing bulk retention capacity. This segmentation enables the towel to maintain higher liquid retention levels for longer periods, improving drying efficiency on large surfaces while keeping the construction relatively simple through layer-by-layer assembly.

AI summary
Drying towels comprise an upper outer material layer formed from a fiber-containing material that is adhered to an upper surface of an inner absorbent material layer. The inner absorbent material layer may comprise one or more surface features that may be openings or grooves. The drying towel includes a lower outer material layer formed from a fiber-containing material that is adhered to a lower surface of the inner absorbent material layer. The inner absorbent material layer upper and lower surface may be covered by the respective upper and lower material layers sandwiching or encapsulating the inner absorbent material layer therebetween. An adhesive material may adhere the upper and lower material layers to the inner adhesive material layer and form a laminate construction. An edging material may be attached along a peripheral edge of the drying towel and cover peripheral ends of the upper and lower outer material layers.
