Monolithic Shoe Upper with Perforated Sole for Ventilation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shoe designs lack efficient ventilating or perspirating properties, and their implementation often requires complex assembly and higher costs.
Innovation Solution
A monolithic upper shoe made of rubber or thermoplastic materials with through openings in the sole for air passage, allowing for easy integration with ventilating or perspirating bottoms, providing forced or natural air exchange without interfering with air circulation, and a specific shock-absorbing bottom design with a non-return vent valve for enhanced comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional solid sole is used in the upper, then the upper provides good protection and structure, but it prevents air circulation between the upper and bottom, eliminating ventilating or perspirating properties
Solution Approach 1:
The sole of the upper is made with through openings (perforations) that allow air to pass through. This transforms the solid sole into a porous structure that maintains mechanical integrity while enabling air circulation between the upper and bottom, thus resolving the contradiction between protection and ventilation capability
2Ease of operation
If ventilated bottoms with compressible pads are used to generate pumping effect, then air exchange is improved, but the assembly complexity and manufacturing cost increase
Solution Approach 1:
The ventilation function is merged into the upper itself by incorporating through openings in the sole. This eliminates the need for separate compressible pads and complex pumping mechanisms in the bottom, allowing air exchange through the simplified structure of the upper-bottom assembly alone
3Object-affected harmful factors
If perspirating bottoms with water-blocking membranes are used, then water prevention is improved, but air passage may be restricted
Solution Approach 1:
The sole of the upper is segmented with multiple through openings distributed across its surface. This segmentation allows air to pass through multiple pathways while the bottom's membrane structure handles water blocking, enabling both functions to operate independently without interference
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 enables shoes to achieve ventilating or perspirating properties with structural simplicity and low cost, enhancing foot comfort through continuous air exchange and shock absorption, while maintaining water prevention.
Implementation Method 1
said bottoms are normally provided with compressible pads that are actually capable - being subject to the pressure discharged on them at every step by the front of the foot - of generating a pumping effect to extract the air contained in the upper and convey it outside the shoe
Implementation Method 2
the sole of said 'monolithic body' is provided with through openings for air passage from inside outside and vice versa
Implementation Method 3
said perspirating bottoms of known type are provided on the front of the foot with holes across the entire thickness that are internally closed by membranes made of materials of known type that are capable of interfering with the rising of water from the ground, but not with air passage
Implementation Method 4
other models of shoes are known, being provided with a bottom with shock-absorbing properties, in association or not with said ventilating properties, in order to exert an advantageous anti-shock function in favor of the user's feet
