Banding Loop With Central Pad for Uniform Antenna Tightening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing strapping devices for securing underwater threat detection antennas on aerial platforms are prone to deformation and accidental release, leading to potential damage and financial loss due to insufficient tightening and deformation of the protective structure.
Innovation Solution
A strapping device with a central pad mounted on the tightening band, which fills the free volume between the band and the object, ensuring uniform tightening force distribution and preventing deformation, along with a tightening/loosening mechanism that maintains loop size within predetermined limits to secure the antenna effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If significant tightening of the strapping is applied to secure the antenna, then the antenna is firmly secured, but the protective structure deforms and may cause irreversible damage or accidental release
Solution Approach 1:
The patent introduces a central pad as an intermediary element positioned at the center of the tightening band. This pad acts as a mediator that distributes the tightening force uniformly across the protective structure, preventing localized stress concentration that would cause deformation. The pad's central positioning and larger surface area allow it to disperse the force from the tightening band's free volume region, securing the antenna reliably while protecting the structural integrity.
Solution Approach 2:
The patent applies local quality by placing a specifically designed central pad only at the critical center region where the tightening band creates free volume. This localized intervention addresses the specific problem area without modifying the entire strapping system. The pad's material properties and geometric shape are optimized for its specific function of force distribution in the high-stress central region.
2Ease of operation
If the tightening band has free volume between the band and the object, then the band can be tightened, but deformation of the protected object occurs
Solution Approach 1:
The central pad serves as an intermediary that fills the free volume between the tightening band and the protective structure. When the tightening band is pulled, the pad transmits the force uniformly to the protective structure, eliminating the free volume effect that causes deformation. The pad's presence allows the band to maintain tension without creating localized stress points.
Solution Approach 2:
The patent changes the physical parameters at the contact interface by introducing a pad with specific material properties (compressibility, surface area) and geometric parameters (thickness, shape). These parameter changes allow the system to accommodate the tightening force while maintaining the protective structure's shape, transforming the direct contact geometry into a distributed contact system.
