Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hose reel deck boxes with unitary sidewalls face challenges in resisting torque and stress during hose winding, leading to distortion and increased manufacturing costs due to the need for complex molds and extensive support structures, which also compromise aesthetics and durability.
Innovation Solution
A hose reel deck box design featuring a unitary housing component with substantially flat sidewalls and a basket assembly coupling assembly that supports the sidewall, utilizing a stiffener to maintain the housing in a stable configuration and reduce wear and tear, while minimizing the need for complex mold features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If robust metal housing assemblies are used to resist torque and stress, then strength and reliability are improved, but manufacturing cost and assembly time increase
Solution Approach 1:
The patent changes the material parameter from metal to plastic and modifies the structural parameters by adding specific reinforcement features (ribs, trusses, mounting structures) molded into the plastic housing. This allows the plastic housing to achieve metal-level strength while maintaining lower manufacturing costs and simpler assembly processes.
Solution Approach 2:
The patent creates a composite structure by combining plastic material with molded-in reinforcement elements (ribs, trusses, and mounting features). This composite approach allows the housing to exhibit enhanced mechanical properties comparable to metal while retaining the manufacturing advantages of plastic injection molding.
2Strength
If plastic housing assemblies with extensive support structures are used to resist forces, then strength is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent merges the support structures (ribs, trusses, mounting features) directly into the housing sidewalls through injection molding. This integration eliminates the need for separate support components and reduces assembly steps, thereby reducing device complexity while maintaining strength.
Solution Approach 2:
The patent modifies the structural parameters of the plastic housing by incorporating specific geometric features (ribs, trusses, mounting structures) during the molding process. These parameter changes enable the plastic housing to resist applied forces without requiring extensive separate support structures.
3Ease of manufacture
If a single molded piece housing assembly is used to reduce assembly cost, then ease of manufacture is improved, but manufacturing precision and reliability decrease
Solution Approach 1:
The patent applies local quality by providing different structural characteristics at different locations within the housing. Critical areas (sidewalls, mounting regions) incorporate reinforcement features like ribs and trusses, while other areas maintain simpler geometry. This localized differentiation enables the single-piece housing to achieve the necessary precision and reliability without compromising manufacturability.

AI summary
A basket assembly coupling assembly is provided. The basket assembly coupling assembly is structured to support a unitary housing component. That is, a unitary sidewall is thin and subject to wear and tear resulting from stress on the unitary sidewall when the hose, and more specifically the basket assembly, is wound. The basket assembly coupling assembly is structured to support the unitary sidewall proximate the coupling of the basket assembly to the unitary sidewall.
