Modular Pivoting Hose Locking for Adjustable Blower Length
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing directable pivoting hoses in portable blower or atomizer machinery have limited movement capacity and rigidity, making them inconvenient and inflexible for operators, as they need to withstand both directing and pivoting efforts and flow pressures, and often require replacement when different lengths are needed.
Innovation Solution
A telescopic and combinable hose design featuring modular segments with selective locking means, including crown segments and a bezel, allowing for adjustable length and high mechanical resistance, enabling the hose to expand or contract and connect multiple segments for variable length and improved operational flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the hose is made with fixed length and limited movement capacity to maintain adequate rigidity, then the hose can resist crushing and withstand static and dynamic pressure, but the operator freedom of movement and operational flexibility are limited
Solution Approach 1:
The hose is divided into multiple modular segments (first segment, second segment, third segment) that can be interconnected. Each segment has a locking mechanism that can engage or disengage independently, allowing the hose to be configured in different lengths and movement capacities while maintaining structural integrity when locked, thus resolving the contradiction between rigidity and flexibility.
2Reliability
If the hose has fixed length to maintain structural integrity, then the hose can withstand flow pressures, but the hose requires replacement when different lengths are needed for different work requirements
Solution Approach 1:
The hose incorporates dynamic locking mechanisms that allow the operator to adjust the effective length of the hose by engaging or disengaging the locking mechanisms at different segments. This enables the hose to adapt to different work requirements (shorter or longer configurations) while maintaining structural integrity when the locking mechanisms are engaged, eliminating the need for replacement.
3Strength
If the hose is made with limited movement capacity to maintain rigidity, then the hose can resist crushing, but the operator convenience and freedom of movement are reduced
Solution Approach 1:
The hose is segmented into multiple independent sections with individual locking mechanisms. When the locking mechanisms are disengaged, each segment can move independently, providing the operator with freedom of movement and ergonomic ease. When the locking mechanisms are engaged, the segments are fixed relative to each other, providing the necessary rigidity to resist crushing and withstand pressure.

AI summary
A directable, pivoting hose for portable atomizers or blowers comprises a head portion (4a) and a tail portion (4c) suitable to define respective interpenetration seat and an elongated portion (4b) interposed between the head portion (4a) and the tail portion (4c) along an axis of development (3); the hose further comprises selective locking means (5) integral obtained into the head portion (4a) and/or the tail portion (4c) and reversibly configurable between an unlocked condition in which they lie undeformed and in which they allow approaching or distancing movements of hookable components to the head portion (4a) and/or tail portion (4c) at their respective interpenetration seat, and between a locked condition in which they are deformed so as to bind hookable components in the interpenetration seats.
