Detachable Engine Stand Mounting Head for Worm Gear Rotation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Worm gear driven engine stands lack the ability to remove the mounting head for engine attachment and require separate handles for rotation and steering, leading to operational interference and inefficiency.
Innovation Solution
A detachable steering handle supported by an adaptor plate with slots for a work tray, and a quick release detent pin for separating the mounting head collar from the drive shaft, allowing for easy installation and removal without interfering with the crank handle operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a worm gear driven gear box is used for rotating the mounting head, then easier and better control of rotation is achieved, but the mounting head cannot be removed for engine attachment and separate steering handle is required causing operational interference
Solution Approach 1:
The mounting head assembly is segmented into a removable component that can be detached from the drive shaft. The drive shaft remains connected to the worm gear mechanism, while the mounting head can be separated for engine attachment, resolving the contradiction between rotational control and adaptability.
Solution Approach 2:
The adaptor plate serves multiple functions: it provides mounting positions for the steering handle, supports the work tray, and allows passage of the drive shaft. This multi-functionality enables the system to accommodate both steering operations and mounting head removal without interference.
2Stability of the object's composition
If the steering handle is permanently fixed on the engine stand, then steering stability is improved, but it interferes with crank handle operation and mounting head removal
Solution Approach 1:
The steering handle is segmented from the main structure and attached via detachable fasteners to the adaptor plate. This segmentation allows the handle to be securely fixed during steering operations while enabling easy removal or repositioning when crank handle operation or mounting head removal is required.
Solution Approach 2:
The steering handle transitions from a fixed state during steering operations to a removable state during mounting head installation. The adaptor plate with multiple slot positions provides dynamic reconfiguration capability, allowing the handle to be moved to different positions or removed entirely when needed.

AI summary
A wheeled engine stand and a process of using the engine stand is provided. The engine stand provides a wheeled base supporting a mounting head with retainers. The mounting head is reversibly attached to a drive shaft through, a retaining pin extending through a mounting head collar. A steering handle is detachably supported on an upper adaptor plate to allow for movement for the wheeled base.
