Air Hose Clamp and Hook Assembly for One-Way Hose Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Pneumatic tools used in industries like roofing often cause accidents due to tangled or retracting air hoses, leading to strain on the operator's hand as they need to be manually managed for continuous operation.
Innovation Solution
An air hose clamping mechanism and hook device that allows one-way movement of the air hose, preventing retraction and reducing hand strain by suspending the tool via a J- or U-shaped hook with a pawl mechanism and adjustable tension, enabling hands-free operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the air hose is left free-moving to allow tool operation, then the tool can be used freely, but the hose becomes tangled or retracts causing the tool to fall and creating hand strain from manual management
Solution Approach 1:
The air hose system is segmented into a fixed portion (clamped to the tool) and a free portion (allowing movement). The clamp mechanism divides the hose management function into separate components: the clamping element that secures the hose and the release mechanism that allows controlled detachment.
Solution Approach 2:
The clamp is pre-positioned on the air hose before tool operation begins. The spring mechanism is pre-loaded to provide immediate clamping force, and the pawl is pre-positioned to engage with the ratchet teeth, establishing the secured state before any retraction or tangling can occur.
2Reliability
If the air hose is manually managed to prevent tangling, then hose stability is improved, but hand strain increases and operational efficiency decreases
Solution Approach 1:
The spring-loaded clamp mechanism is self-actuating and maintains clamping force automatically without requiring continuous manual intervention. The pawl-ratchet mechanism provides automatic one-way locking that prevents retraction without operator input, allowing the system to serve itself throughout the tool's operational cycle.
Solution Approach 2:
The function of manual hose management is extracted from the operator's tasks and transferred to the automated clamp mechanism. The clamp independently handles hose securing, releasing the operator from this secondary task so they can focus solely on operating the pneumatic tool.
3Reliability
If a clamping mechanism is added to prevent hose retraction, then hose stability is improved, but device complexity increases
Solution Approach 1:
The clamp mechanism merges multiple functions into a single integrated assembly: the spring provides both the clamping force and the release mechanism, the pawl combines with the ratchet teeth to create the one-way lock, and all components are mounted on a single bracket that attaches to the tool. This consolidation minimizes the number of separate parts and simplifies installation.
Solution Approach 2:
Instead of using a complex motorized or electronically-controlled locking system, the invention inverts the approach by using a simple spring-loaded mechanism with passive pawl-ratchet engagement. The system relies on mechanical advantage and elastic energy storage rather than active control systems, reducing complexity while maintaining reliability.

Function Achieved in This Case
Prevents air hose retraction and reduces operator hand strain, allowing for safer and more efficient use of pneumatic tools by securing the hose in place, enabling workers to focus on tasks without manual hose management.
Implementation Method 1
a spring positioned in the pawl to apply a clamping force
Implementation Method 2
The friction between the spring and air hose prevents unintended movement, while still allowing controlled adjustment
