Solution Overview
Problem
The production process of traditional 'leather bones' for dogs involves harmful chemical components such as hydrogen peroxide, dyes, preservatives, and glues, posing health risks to animals.
Innovation Solution
A process using only leather scrapings as raw material, with sodium metabisulfite as a preservative, and mechanical steps like rinsing, cutting, storage, and drying, eliminating the need for harmful chemical components like flavorings, dyes, resins, and glues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional chemical treatment processes are used to produce leather bones, then the product durability and appearance are improved, but harmful chemical residues remain that pose health risks to animals
Solution Approach 1:
The patent removes harmful chemical substances from the production process entirely. Instead of using traditional chemical baths with hydrogen peroxide, dyes, and preservatives, the invention extracts only the essential mechanical processing steps (cleaning, cutting, shaping, drying) to produce leather bones without toxic residues, thereby eliminating the harmful factor while maintaining product functionality
Solution Approach 2:
The patent changes the production parameters from chemical-based to mechanical-based processing. The treatment conditions are modified to use physical methods (mechanical cleaning, thermal drying at controlled temperatures) instead of chemical treatments, fundamentally altering the production approach to eliminate harmful chemical exposure while achieving the desired product properties
2Duration of action of stationary object
If multiple chemical components are used in production, then the product appearance and preservation are enhanced, but the complexity of the production process increases
Solution Approach 1:
The patent extracts and eliminates multiple chemical components (dyes, artificial flavorings, preservatives, glues, resins) from the production process, reducing it to essential mechanical and thermal processing steps. This simplification removes unnecessary complexity while maintaining product preservation through proper drying and storage conditions
Solution Approach 2:
The patent uses leather scrapings as a universal raw material that can be processed into various leather bone shapes and sizes without requiring different chemical treatments for each product variant. The mechanical processing method is universally applicable to different leather materials, simplifying the overall production system
3Object-affected harmful factors
If leather scrapings are used as raw material without chemical treatment, then the naturalness and safety of the product are improved, but the manufacturing precision and consistency may be affected
Solution Approach 1:
The patent applies preliminary mechanical cleaning and preparation to the leather scrapings before processing. By pre-cleaning and standardizing the raw material through mechanical means (removing hair, fat, and impurities), the invention ensures consistent product quality while maintaining the natural, chemical-free processing approach throughout production
Solution Approach 2:
The patent controls physical parameters (temperature, humidity, drying time, mechanical processing forces) to ensure manufacturing precision and product consistency. By carefully managing these physical parameters instead of relying on chemical treatments, the invention achieves repeatable results while maintaining product safety and naturalness
