Detachable Combination Shoe for Workshop and Office Use
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing combination shoes are primarily designed for safety purposes and lack versatility, making them unsuitable for use in multiple environments such as workshops and offices, and they do not offer effective protection against electrostatic discharges or easy cleaning and sterilization.
Innovation Solution
A combination shoe design featuring a detachable outer shoe with a form-fitting holder and a textile inner shoe, incorporating features like through holes for drainage, interlocking devices, and an ESD-compatible outer shoe upper made from flexible material with an electrically conductive mesh, allowing for easy separation of soiled and clean components, and autoclavability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the shoe is designed as a safety shoe with protective elements, then protection function is improved, but versatility for different environments deteriorates
Solution Approach 1:
The shoe is divided into two separable parts: an outer shoe made of impermeable material for protection and cleaning, and an inner shoe made of textile material for comfort and office use. This segmentation allows each part to serve different functions and environments independently.
Solution Approach 2:
The combination shoe system provides multiple functions: the outer shoe serves for workshop/safety environments where protection and cleaning are needed, while the inner shoe serves for office environments where comfort and aesthetics are prioritized. The system thus adapts to different environmental requirements.
2Reliability
If the outer shoe upper is made from impermeable material, then protection and cleaning capability is improved, but breathability and comfort deteriorate
Solution Approach 1:
The shoe upper is segmented into an outer shoe upper made of impermeable material for protection and an inner shoe upper made of breathable textile material for comfort. This segmentation allows each layer to optimize its properties without compromise.
Solution Approach 2:
The inner shoe acts as an intermediary layer between the foot and the impermeable outer shoe. It provides breathability and comfort close to the foot, while the outer shoe provides protection, thus mediating between conflicting requirements.
3Ease of manufacture
If the shoe is designed for easy cleaning and sterilization, then maintenance capability is improved, but electrostatic discharge protection deteriorates
Solution Approach 1:
The shoe is segmented into an outer shoe that can be easily cleaned and sterilized (impermeable material) and an inner shoe that provides ESD protection (conductive textile material). This segmentation allows each component to optimize its properties for its specific function.
Solution Approach 2:
The outer shoe combines impermeable material with conductive elements (such as metal mesh or conductive threads) to achieve both cleanability and ESD protection. The composite structure allows the shoe to withstand cleaning processes while maintaining electrostatic discharge capabilities.
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 solution provides a versatile shoe that offers personal and product protection, is washable, decontamiable, and sterilizable, while preventing electrostatic discharges, allowing for separation of soiled and clean components, and meets safety standards for various environments.
Implementation Method 1
a mesh made of electrically conductive material
Implementation Method 2
The outer shoe sole can have at least one through hole for cleaning fluid to drain off during the cleaning process of the outer shoe
Implementation Method 3
The outer shoe (2) and / or the inner shoe (3) are or is autoclavable. The combination shoe can, for example, be autoclavable with the following parameters: 3 min at 135 ° C ambient temperature and 2 bar ambient pressure

AI summary
A combination shoe (1) comprising an outer shoe (2) and an inner shoe (3) is described. The outer shoe (2) has an outsole (21) and an upper (22). The inner shoe (3) is designed as a textile sock, comprising a footbed and/or insole (31) and an inner upper (32). The inner shoe (3) in the area of the outer side of its sole and the outer shoe in the area of the inner side of its sole are, at least in some areas, designed to fit together in a form-fitting manner.
