Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing faucet sprayer hose assemblies lack efficient integration of energy transmission and fluid delivery systems, leading to potential damage and limited functionality due to rigid energy wire configurations and contact with metallic components.
Innovation Solution
A sprayer hose assembly featuring a waterway tube with a helically applied energy wire configuration, isolated by a covering layer, which allows for flexible energy transmission and reduces contact with metallic components, enabling enhanced durability and functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If rigid energy wire configurations are used in sprayer hose assemblies, then electrical connection stability is improved, but flexibility and resistance to damage are worsened
Solution Approach 1:
The patent applies this principle by enclosing rigid energy wires within a flexible covering layer that allows the hose to bend and flex without damaging the internal electrical wires. The covering layer acts as a protective shell that maintains wire integrity while enabling hose flexibility.
Solution Approach 2:
The patent segments the hose assembly into distinct functional layers: an inner waterway tube for fluid delivery, energy wires for electrical transmission, and an outer covering layer for protection and flexibility. This segmentation allows each component to be optimized independently.
2Device complexity
If energy wires are positioned close to metallic components, then device complexity is reduced, but electrical interference and damage risk increase
Solution Approach 1:
The patent introduces non-conductive materials as intermediary layers between energy wires and any metallic components. The covering layer serves as this intermediary, electrically isolating the energy wires from metallic parts while maintaining structural integrity.
Solution Approach 2:
The patent creates an electrically inert environment by surrounding energy wires with non-conductive covering material, effectively shielding them from electrical interference that would occur if they contacted metallic components.
3Ease of manufacture
If traditional sprayer hose configurations are used, then manufacturing simplicity is maintained, but durability and functionality are limited
Solution Approach 1:
The patent employs composite construction by combining different materials with complementary properties: flexible polymer materials for the waterway tube and covering layer, conductive materials for energy wires, and non-conductive materials for isolation. This composite approach enhances durability while maintaining manufacturability.
Solution Approach 2:
The patent implements a nested structure where energy wires are positioned within the waterway tube, which is itself enclosed by a protective covering layer. This nested arrangement protects internal components while maintaining a compact, manufacturable design.
