Solution Overview
Problem
Conventional high pressure fluid rotary nozzle handling systems face issues with belt drive unit failures, jamming, and maintenance, requiring lengthy disassembly and repair processes that cause significant downtime.
Innovation Solution
A modular drive unit design with toolless fasteners and quick-disconnect features allows for easy assembly and disassembly, enabling rapid component replacement and maintenance without tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If conventional drive units use traditional fastening methods (screws, bolts), then structural integrity and reliability are maintained, but disassembly and repair time increases significantly
Solution Approach 1:
The drive unit is divided into modular components (housing, belt drive units, motor assembly) that can be independently removed and replaced. The housing includes removable side panels and a removable bottom panel, allowing access to internal components without complete disassembly. This segmentation enables rapid repair by replacing entire modules rather than individual parts.
Solution Approach 2:
The belt drive units are designed to be easily extracted from the housing through removable side panels and channels. The motor assembly can be removed through the top opening. This extraction capability allows quick removal of failing components for replacement without requiring complex disassembly procedures.
2Ease of manufacture
If drive units are designed as integrated assemblies, then structural strength is maximized, but maintenance and component replacement become difficult
Solution Approach 1:
The housing is segmented into multiple removable panels (side panels, bottom panel) that can be detached to access internal components. The belt drive units are separate assemblies that can be removed independently. This segmentation maintains structural integrity when assembled while providing easy access for maintenance.
Solution Approach 2:
The housing transitions from a static sealed enclosure to a dynamic structure with removable panels. The side panels can be removed to access belt drive units, and the bottom panel can be removed for component access. This dynamic configuration allows the structure to adapt between operational integrity and maintenance accessibility.
3Ease of repair
If traditional fasteners are used throughout the drive unit, then reliable connections are achieved, but repair procedures become time-consuming and complex
Solution Approach 1:
The belt drive units are designed to be extracted through removable side panels without requiring removal of other components. The motor assembly can be extracted through the top opening. This extraction design enables rapid replacement of failing components, significantly improving repair efficiency.
Solution Approach 2:
The housing is pre-configured with removable panels and access channels during manufacturing, preparing the structure for quick disassembly. The belt drive units are pre-positioned in accessible locations with predetermined access paths. This preliminary configuration eliminates the need for complex disassembly procedures during repair.

AI summary
Disclosed are lance hose drive units having a modular construction for easy disassembly and reassembly of its housing and components. A drive unit includes a housing having front and rear walls, and a top cover coupled to the walls. The housing may include a bottom cover removably also coupled to the front and rear walls, and a motor-side cover coupled to a side edge of at least one of the front wall, rear wall, and top cover. A drive unit may also comprise a belt drive unit positioned within the housing, and configured to drive movement of a lance hose positioned within the housing. A belt-side cover is removably coupled to the top cover, at least one toolless fastener removably securing the belt-side cover. The belt drive unit is slidably coupled at its front end within an interior front channel and at its rear end within an interior rear channel.
