Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional shoe materials are poorly breathable, leading to discomfort and odor issues, and are environmentally unfriendly due to non-decomposability and pollutant release, while coffee grounds are underutilized and contribute to waste management problems.
Innovation Solution
A method involving mixing coffee grounds with diatomaceous earth to create a porous structure, combining with natural rubber to form a filling material that is molded into shoe parts, allowing for deodorization, dehumidification, and natural decomposition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If general shoe materials (polyurethane, leather) are used, then structural strength and durability are achieved, but air permeability is poor leading to heat and moisture accumulation
Solution Approach 1:
The patent incorporates coffee grounds material which forms a porous structure that allows air permeability while maintaining structural integrity. The porous nature of coffee grounds enables heat and moisture to escape, improving breathability without sacrificing strength.
Solution Approach 2:
The patent creates a composite material by combining coffee grounds with binding agents and other shoe materials. This composite approach allows the integration of breathable coffee grounds structure with the structural strength provided by traditional shoe materials like polyurethane and leather.
2Ease of manufacture
If general shoe materials (polyurethane, leather) are used, then structural strength is achieved, but environmental decomposability is poor causing pollution
Solution Approach 1:
The patent changes the material composition parameters by substituting a portion of traditional non-decomposable materials with coffee grounds material. This parameter change maintains structural strength through proper formulation while enabling environmental decomposability and reducing pollution.
Solution Approach 2:
The patent converts the waste coffee grounds (which would otherwise be discarded as garbage) into a beneficial shoe material. This transforms an environmental harm (waste accumulation) into a benefit (decomposable, aromatic shoe material) while maintaining structural requirements.
3Object-generated harmful factors
If coffee grounds material is used to improve breathability, then air permeability and deodorization are enhanced, but manufacturing complexity increases
Solution Approach 1:
The patent merges multiple functions into the coffee grounds material itself: it provides breathability through its porous structure, deodorization through coffee aroma, and structural contribution through its fibrous nature. This consolidation reduces the need for separate functional components and simplifies the overall manufacturing process.
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 method produces breathable, deodorizing, and recyclable shoe parts that reduce environmental impact by utilizing waste coffee grounds and diatomaceous earth, offering a sustainable and cost-effective solution.
Implementation Method 1
the pores have a diameter larger than a diameter of gaseous molecules, so that the coffee aroma is passed through the plurality of pores of the rubber material
Implementation Method 2
mixing a coffee grounds material with a porous material in a stirring manner to form a porous structure with coffee aroma

AI summary
A method for manufacturing a shoe part includes: the first mixing step, the standing step, the second mixing step, the setting step, and the hot press forming step. The invention mainly uses the waste coffee grounds material as raw material to manufacture the shoe part. In addition to the aroma of coffee, the shoes have the functions of deodorization and dehumidification while being worn by the user, thereby achieving multiple objectives of environmentally friendly materials, low cost, strong structure and environmentally friendly after-use treatment.
