Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing adhesive tapes face challenges in achieving strength greater than duct tape while remaining cost-competitive and easy to use, with issues such as stress under extreme temperatures in outdoor applications.
Innovation Solution
A high-strength adhesive tape is developed, comprising a scrim layer, a fabric layer, and multiple adhesive layers, where the scrim layer is coated with adhesive on one side and treated with an anti-stick agent on the other, and the fabric layer is coated with adhesive to ensure bonding and durability, allowing the tape to attach to external objects while resisting deformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the adhesive strength is increased to exceed duct tape, then the bonding capability is improved, but the tape becomes more difficult to use and less cost-competitive
Solution Approach 1:
The patent applies different adhesive formulations to different regions of the tape. The first adhesive layer uses a stronger adhesive formulation for bonding to external objects, while the second adhesive layer uses a weaker, more manageable formulation for bonding between tape layers. This local differentiation allows the tape to achieve high external bonding strength while maintaining ease of application and removal.
Solution Approach 2:
The patent employs composite adhesive systems with multiple layers having different properties. The first adhesive layer comprises a stronger adhesive formulation, while the second adhesive layer comprises a weaker adhesive formulation. This composite approach enables the tape to simultaneously achieve high external bonding strength and ease of operation by selecting appropriate adhesive materials for each specific function.
2Strength
If the adhesive strength is increased to exceed duct tape, then the bonding capability is improved, but the manufacturing cost increases
Solution Approach 1:
The patent applies different adhesive formulations to different regions of the tape. The first adhesive layer uses a stronger adhesive formulation for bonding to external objects, while the second adhesive layer uses a weaker, more cost-effective formulation for bonding between tape layers. This local differentiation allows the tape to achieve high external bonding strength while maintaining cost-effectiveness.
Solution Approach 2:
The patent employs composite adhesive systems with multiple layers having different properties. The first adhesive layer comprises a stronger adhesive formulation, while the second adhesive layer comprises a weaker, more cost-effective adhesive formulation. This composite approach enables the tape to simultaneously achieve high external bonding strength and cost-effectiveness by selecting appropriate adhesive materials for each specific function.
3Strength
If the tape strength is increased to resist tearing, then the durability is improved, but the tape becomes more difficult to cut or rip into pieces
Solution Approach 1:
The patent creates a situation where the first adhesive layer has stronger bonding characteristics for external objects, while the second adhesive layer has weaker bonding characteristics that allow for easier separation. This local differentiation in adhesive strength enables the tape to be both durable during use and easy to cut or rip into pieces when needed.
Solution Approach 2:
The patent employs composite adhesive systems with multiple layers having different bonding strengths. The first adhesive layer comprises a stronger adhesive formulation for bonding to external objects, while the second adhesive layer comprises a weaker adhesive formulation that facilitates easy separation. This composite structure enables the tape to simultaneously achieve durability and ease of cutting.
4Ease of operation
If the tape is designed for easy removal without residue, then the ease of operation is improved, but the adhesive strength during use is reduced
Solution Approach 1:
The patent applies different adhesive formulations to different regions of the tape. The first adhesive layer uses a stronger adhesive formulation for bonding to external objects during use, while the second adhesive layer uses a weaker, more easily removable formulation for bonding between tape layers. This local differentiation allows the tape to achieve strong external bonding while maintaining ease of removal.
Solution Approach 2:
The patent employs composite adhesive systems with multiple layers having different properties. The first adhesive layer comprises a stronger adhesive formulation for bonding to external objects during use, while the second adhesive layer comprises a weaker, more easily removable adhesive formulation. This composite approach enables the tape to simultaneously achieve strong external bonding and ease of removal.
