Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If adhesive-coated polyurethane wound dressings are used, then wound protection is provided, but skin reactions and allergic reactions occur
Solution Approach 1:
The patent removes the adhesive component from the wound dressing system. The chia seed hydrogel itself provides self-adhesive properties through its natural polysaccharide structure, eliminating the need for separate adhesive coatings that cause skin reactions and allergic responses.
Solution Approach 2:
The patent changes the material parameters by using natural chia seed polysaccharides instead of synthetic adhesives. This parameter change maintains the necessary adhesive function while eliminating the harmful effects of conventional adhesives on sensitive skin.
2Duration of action of stationary object
If adhesive wound dressings are used for long periods, then wound coverage is maintained, but the area becomes sticky and external damage occurs
Solution Approach 1:
The patent eliminates the adhesive layer that causes stickiness and damage. The chia seed hydrogel provides inherent adhesive properties through its polysaccharide structure, allowing long-term wear without the harmful sticky residue and skin damage associated with conventional adhesives.
3Reliability
If physical barrier methods are used to protect wounds, then external contamination is prevented, but bacteria are trapped causing healing delay
Solution Approach 1:
The chia seed hydrogel forms a porous network structure that acts as a physical barrier to external contaminants while maintaining permeability to allow trapped bacteria to be eliminated. The hydrogel matrix provides protection without creating a sealed environment that would trap and preserve bacteria.
4Reliability
If commercial hydrogel films are used, then wound protection is provided, but medical expenses increase
Solution Approach 1:
The patent uses chia seed hydrogel, a biodegradable material derived from abundant natural sources, to create a cost-effective wound dressing. The natural polysaccharide structure provides adequate protection for the healing period and then degrades, eliminating the need for expensive synthetic materials and reducing overall medical expenses.
Solution Approach 2:
The patent creates a composite wound dressing using chia seed hydrogel combined with appropriate formulations to achieve the desired mechanical and biological properties. This composite approach using natural materials provides an affordable alternative to expensive commercial hydrogel films while maintaining effective wound protection.

Function Achieved in This Case
The composition exhibits excellent self-adhesive properties, high tensile strength, and effective antibacterial and wound-healing effects, while being cost-effective and hypoallergenic, thus addressing the limitations of existing wound dressings.
Implementation Method 1
The shells of fully hydrated chia seeds release anionic heteropolysaccharides and have high water retention capacity and high viscosity and thickening effects
Implementation Method 2
preparation of electrospinning and film products has been proposed by mixing PVA with plant seed mucilage, including chia seed mucilage
Implementation Method 3
the shells of fully hydrated chia seeds release anionic heteropolysaccharides and have high water retention capacity
Implementation Method 4
Polyvinyl alcohol (PVA) is a non-toxic water-soluble polymer obtained by hydrolyzing polyvinyl acetate
Implementation Method 5
The pharmaceutical composition exhibits excellent self-adhesive properties, so the pharmaceutical composition can be directly attached to the skin and withstand joint movement through excellent deformation adaptability and has high tensile strength. The pharmaceutical composition also has an antibacterial effect and an excellent wound-healing effect
