Integrated Hose Clamp Structure to Prevent Band Deformation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional clamps for fixing hoses and pipes in vehicles are costly due to numerous separate parts, prone to deformation during tightening, and not reusable, leading to reduced fastening force and increased risk of part loss.
Innovation Solution
A clamp with a band portion, integrally formed nut and washer portions, and a bolt that reduces or increases the band's diameter, featuring a perforated section and support structures to prevent deformation and enhance holding power, allowing for cost reduction, weight reduction, and improved fastening force.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple separate parts (band, washer, nut) are used in conventional clamps, then the fastening function is achieved, but the cost increases and the risk of part loss increases
Solution Approach 1:
The band portion, nut portion, and washer portion are integrated into a single unified clamp structure. The nut portion and washer portion are formed as one integral component that is directly connected to the band portion, eliminating the need for separate assembly of multiple parts while maintaining the fastening function.
2Reliability
If separate parts are assembled in conventional clamps, then the fastening function is achieved, but weight increases
Solution Approach 1:
By integrating the band, nut, and washer into a single clamp structure, the total weight is reduced compared to assembling multiple separate parts. The unified structure eliminates redundant materials and connection interfaces, achieving weight reduction while maintaining fastening functionality.
3Force
If a bolt is tightened by rotating in conventional clamps, then the fastening force is applied, but the band portion deforms and reuse becomes impossible
Solution Approach 1:
The integrated structure where the nut portion and washer portion are formed as one piece with the band portion prevents differential deformation that occurs in separate parts. The unified construction ensures that when the bolt is tightened, the entire clamp structure deforms uniformly, maintaining the band's integrity and enabling reuse.
Solution Approach 2:
Instead of allowing the band to deform independently under bolt tightening, the integrated design inverts the approach by making the entire clamp structure (including nut and washer) a unified component that distributes and manages the deformation uniformly, preventing band portion damage.

AI summary
A clamp has a structure including a band portion wrapping a circular member, such as a hose, a washer portion, a nut portion, and a connection portion and support portions that prevent the band portion from being deformed when a bolt is tightened, these portions being integrally formed with each other into a single portion. Therefore, reduction in the separate portions causes cost reduction, weight reduction, and reduction in risk of loss of the separate portions, and the performance problem in that the clamp rotates when the tightening work is performed by rotation of the bolt is improved.
