Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hose clamps with bolt-shaped fastening screws face issues such as interference with complex engine compartment elements, insufficient tool manipulation space, risk of tearing, and the need for continuous grooves on the band, leading to reduced assemblability and aesthetics.
Innovation Solution
A band winding type hose clamp design featuring a body with a winder and pivotable cover that allows the band to be securely fastened without continuous grooves, preventing loosening and interference, while providing enhanced aesthetics and ease of use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a bolt-shaped fastening screw is used to fasten the clamp in the circumferential direction of the band, then the clamp can be securely fastened to the hose, but the fastening clamp interferes with various elements installed in the engine compartment and reduces assemblability
Solution Approach 1:
The patent inverts the fastening direction from the conventional circumferential direction to an axial direction. The fastening member fastens the band at an end in the axial direction of the band, which eliminates interference with engine compartment elements while maintaining secure fastening. This inversion resolves the contradiction between fastening security and assemblability.
2Reliability
If the fastening screw is strongly fastened to firmly fasten the clamp, then the clamp is securely fixed, but tearing of the clamp may occur and fastening force decreases
Solution Approach 1:
The patent introduces a compensation mechanism that allows the band to dynamically adjust to hose diameter variations. The band is configured to compensate for diameter changes, which prevents excessive stress concentration that would lead to tearing. This dynamic compensation maintains both fastening security and clamp integrity.
Solution Approach 2:
The patent changes the geometric parameters of the band by forming grooves at uniform intervals instead of continuous grooves. This parameter change allows the band to flex and compensate for diameter variations without tearing, while still providing secure fastening when the fastening member is applied.
3Reliability
If continuous grooves are formed on the band corresponding to fastening screw threads, then the fastening screw can be used, but a separate manufacturing process and expense are required and use of the band is limited
Solution Approach 1:
The patent segments the continuous groove structure into discrete grooves formed at uniform intervals along the band. This segmentation eliminates the need for continuous grooves that would require separate manufacturing processes, while still providing adequate engagement for the fastening member. The segmented structure also allows the band to flex better and prevents tearing.
4Ease of operation
If the band end is allowed to protrude externally during fastening, then the band can be drawn in accordance with fastening, but the band end may interfere with various elements or injure the worker and creates appearance problems
Solution Approach 1:
The patent extracts the problematic protruding band end from the final assembled configuration. By fastening the band at an end in the axial direction using the fastening member, the band end is contained and does not protrude externally. This eliminates interference with engine compartment elements and injury risks to workers, while the fastening process remains effective.
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 solution prevents loosening due to engine vibration, compensates for hose diameter variations, reduces interference with engine compartment elements, and allows for easy tool manipulation, eliminating the need for continuous grooves and enhancing aesthetics.
Implementation Method 1
a band (1) having one end (1a) fixed to a hose (100), the other end (1b) surrounding an outer periphery of the hose (100), and pressing the outer periphery of the hose (100), wherein the band (1) is formed of an elastic material
Implementation Method 2
a winder (20) rotatably coupled to the body (10), the other end (1b) of the band (1) being inserted into the winder (20), the winder (20) winding the other end (1b) of the band (1) in accordance with rotation of the winder (20), thereby causing the band (1) to come into close contact with the outer periphery of the hose (100) while pressing the outer periphery of the hose (100)

AI summary
An example band winding type hose clamp may include: a body part engaged with and fixed to one end of a band; a winding part which is rotatably coupled to the body part, into which the other end of the band surrounding the outer periphery of the hose is inserted, and which is rotated by an external force to wind the other end of the band, whereby the band presses and closely contacts the outer periphery of the hose; and a cover part which is hingedly coupled to the body part spaced apart from the winding part while one end of the cover part is engaged with the winding part, and which selectively restrains the rotation of the winding part so as to maintain the elastic force of the band pressing the outer periphery of the hose.
