Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If breathable meshes are arranged on shoe main bodies, then breathability is improved, but ventilation efficiency remains low and cooling effect is poor
Solution Approach 1:
The patent employs a dynamic ventilation system with an active blowing device (fan) that creates moving air flow through the shoe, replacing static breathable mesh designs. The fan dynamically adjusts air circulation to maintain effective ventilation regardless of external conditions, transforming the passive mesh structure into an active airflow management system.
Solution Approach 2:
The patent utilizes pneumatic principles by introducing a blowing device that generates pressurized air flow through designated channels and outlets. This active pneumatic system forces air circulation through the shoe cavity, significantly enhancing ventilation efficiency compared to passive mesh-based approaches that rely solely on natural diffusion.
2Temperature
If breathable meshes are used, then some ventilation is achieved, but air flow circulation cannot be effectively formed and temperatures inside shoes cannot be effectively lowered
Solution Approach 1:
The ventilation system is segmented into distinct functional components: blowing device, blowing channels, air outlets, and supporting insole with air holes. This segmentation allows each component to perform its specific function efficiently while maintaining overall system manageability despite the added complexity of active cooling.
Solution Approach 2:
The patent introduces air as an intermediary medium to transfer heat away from the foot. The blowing device generates air flow that circulates through the shoe cavity, absorbing heat and moisture, and expelling it through outlets. This intermediary air flow mechanism effectively lowers temperature without requiring direct contact cooling systems.
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 achieves improved ventilation, sweat discharge, and cooling efficiency, reducing discomfort and bacteria breeding, enhancing user experience.
Implementation Method 1
The blowing device sucks the air from the accommodating space and forms a relatively low pressure region in a region of the accommodating space close to the blowing device, so that an air passage rate is increased while the air inside the accommodating space forms an internal circulation path
