Multi-style Moisture-permeable Waterproof Shoe with Removable Inner Unit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sock shoes have a fixed appearance and lack support, making them inconvenient to wear and change styles, as they collapse when not worn and require manual extension to put on.
Innovation Solution
A multi-style moisture-permeable waterproof shoe design featuring an outer shoe body unit with a removable and selectively insertable sock-like inner shoe body unit, which includes a moisture-permeable waterproof inner sleeve, an outer sock body, and an inner adhesive layer, providing support and ease of use by maintaining a three-dimensional shape and allowing for different styles without changing shoes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the upper is made of soft simple woven material to provide better wearability, then comfort is improved, but the upper cannot support a three-dimensional shape and collapses inwardly when not worn
Solution Approach 1:
The patent employs a nested structure where the sock-like inner shoe body unit (providing soft wearability) is inserted into the outer shoe body unit (providing structural support). The inner unit contains a moisture-permeable waterproof inner sleeve that defines the foot space, while the outer unit maintains the three-dimensional shape. This nested arrangement allows the soft inner unit to provide comfort while the rigid outer unit prevents collapse when not worn.
2Ease of operation
If the upper is made of soft simple woven material, then comfort is improved, but the appearance is fixed and cannot be changed to different styles
Solution Approach 1:
The shoe is divided into separable components: the outer shoe body unit and the sock-like inner shoe body unit. The inner unit can be removed and replaced with different units having various appearances, colors, or styles. This segmentation allows users to change styles by swapping inner units while maintaining the comfortable wearability provided by the soft inner material.
3Ease of operation
If the upper is made of soft simple woven material without stiffness, then flexibility is improved, but the upper cannot be quickly worn as it requires manual extension
Solution Approach 1:
The sock-like inner shoe body unit is pre-formed with a three-dimensional shape by the outer shoe body unit, eliminating the need for manual extension during wear. The inner unit is prepared in advance with the proper shape and structure, allowing users to simply insert their foot without the time-consuming process of stretching and shaping soft material.
4Adaptability or versatility
If a removable inner shoe body unit is added to provide style changeability and support, then adaptability and shape support are improved, but device complexity increases
Solution Approach 1:
The outer shoe body unit serves multiple functions: it provides structural support to maintain three-dimensional shape, acts as a waterproof barrier, and serves as a universal container for different sock-like inner shoe body units. This multi-functionality reduces the need for separate components, thereby limiting the increase in overall device complexity while achieving style changeability and shape support.
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 design allows for quick and comfortable wear, supports a three-dimensional shape, and enables users to match outfits without changing shoes, while maintaining waterproof and moisture-permeable functionality.
Implementation Method 1
The inner adhesive layer is adhered between an outer surface of the moisture-permeable waterproof shoe-like inner sleeve and an inner surface of the sock body portion
Implementation Method 2
a moisture-permeable waterproof shoe-like inner sleeve defining a foot space that has an open top end and a closed bottom end

AI summary
A multi-style moisture-permeable waterproof shoe includes an outer shoe body unit defining an insertion space, and a plurality of sock-like inner shoe body units inserted removably and selectively into the insertion space. Each sock-like inner shoe body unit includes a moisture-permeable waterproof shoe-like inner sleeve and an outer sock body. The shoe-like inner sleeve defines a foot space and is made from at least one cut piece. The outer sock body has a sock body portion sleeved on the shoe-like inner sleeve. An inner adhesive layer is adhered between an outer surface of the shoe-like inner sleeve and an inner surface of the sock body portion.
