Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current shear stress-resistant systems with anisotropic properties are non-specific, leading to unintended binding and require protective release liners, increasing production costs and environmental impact.
Innovation Solution
A liner-free attachment system with an anchoring site and a detachable article that uses a part A coating for specific binding, providing high shear resistance and easy detachment, eliminating the need for release liners.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If non-specific binding materials are used to achieve shear stress resistance, then attachment strength is improved, but unintended binding to various surfaces occurs requiring release liners
Solution Approach 1:
The patent applies local quality by creating a coating composition with specific chemical properties (carboxyl groups, hydroxyl groups, amine groups) that provide selective binding capability. This localized chemical functionality enables the coating to bind strongly to specific surfaces containing complementary functional groups while remaining non-binding to surfaces without these groups, thereby achieving both shear stress resistance and reduced unintended binding without requiring release liners.
2Object-generated harmful factors
If release liners are used to prevent unintended binding, then non-specific binding is controlled, but production costs and environmental impact increase
Solution Approach 1:
The patent extracts and eliminates the release liner component from the attachment system by developing a coating composition that inherently prevents unintended binding through its selective chemical properties. The coating's functional groups (carboxyl, hydroxyl, amine) provide specific binding capability that removes the need for separate protective liners, thereby reducing material costs, simplifying manufacturing, and decreasing environmental impact from liner waste.
3Strength
If non-specific binding materials are used, then shear stress resistance is achieved, but material waste and environmental impact increase
Solution Approach 1:
The patent applies parameter changes by modifying the chemical composition parameters of the coating to include specific functional groups (carboxyl groups at 0.1-10 mmol/g, hydroxyl groups at 0.1-10 mmol/g, amine groups at 0.1-10 mmol/g) that enable selective binding. This parameter optimization allows the coating to achieve high shear stress resistance through specific molecular interactions while minimizing material waste by preventing unintended binding to surfaces, thereby reducing the need for release liners and associated material waste.
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 system reduces production costs and environmental impact by allowing for easy and clean attachment and removal, with high resistance to shear stress and compatibility with various materials, while maintaining attachment integrity across different environmental conditions.
Implementation Method 1
The detachable article typically contains a coating, referred to herein as the 'part A coating,' on the side or portion of the article that attaches to the anchoring site

AI summary
A reusable, liner-free attachment system is described herein. The attachment system is compatible with the surfaces of a variety of materials, regardless of composition or physical characteristics. The system contains an anchoring site and a detachable article that binds specifically to the anchoring site. When bound together, the system provides anisotropic resistance to applied forces. The system is highly resistant to shear stress, but is easily detached by applying a pull-off force. The article typically contains a part A coating on the side or portion of the article that attaches to the anchoring site. The system can be used with a variety of articles, such as hooks, carpet tiles, medical devices, such as blood pressure cuff; climbing equipment, such as gloves, shoes or handles.
