Pivoting Handle with Cam-Arm Locking for Compact Portable Dehumidifier
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current dehumidifiers are bulky, difficult to move, not rugged, and inefficient, making them unsuitable for quick moisture removal in applications like fire and flood restoration.
Innovation Solution
A portable dehumidifier design featuring a compact and rugged cabinet with a pivoting handle, unique wheel mounting brackets for increased compactness, and a fan control method that adjusts speed based on delta temperature between ambient and exhaust temperatures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If current dehumidifier designs are used, then dehumidification function is provided, but the device is bulky and difficult to move
Solution Approach 1:
The handle is designed to pivot between a stored position (flush with the cabinet) and an engaged position (extended outward). This dynamic configuration allows the handle to provide ergonomic gripping capability when needed while maintaining a compact profile during transport, directly resolving the contradiction between ease of operation and compact size.
2Strength
If current dehumidifier designs are used, then dehumidification function is provided, but the device is not rugged
Solution Approach 1:
The handle assembly is segmented into distinct functional components: the handle body, the pivoting mechanism, the cam arm, and the locking pin. This segmentation allows each component to be optimized for its specific function while contributing to overall ruggedness. The modular structure enables robust construction without excessive complexity, as each segment can be independently strengthened or simplified based on its operational requirements.
3Ease of operation
If the handle is always extended for easy gripping, then ease of operation is improved, but the device volume increases
Solution Approach 1:
The handle pivots between two stable positions: extended outward for gripping during operation, and folded flush against the cabinet for compact storage and transport. The cam arm and locking pin mechanism maintain the handle in the extended position during use, then allow it to fold flat when engaged, dynamically adapting the device's effective volume to operational needs.
Solution Approach 2:
The pivoting handle serves multiple functions: it provides an ergonomic gripping surface during operation, folds flat to minimize device volume during transport, and the cam arm mechanism provides both handling assistance and locking functionality. This multi-functionality resolves the contradiction by making the same structural element serve both ergonomic and compactness requirements at different times.

AI summary
A portable dehumidifier includes a cabinet and a pivoting handle. The pivoting handle is configured to pivot from a stored position to an engaged position. The pivoting handle includes a cross member, two extension members, and a cam arm. The cam arm is coupled to one of the extension members at an end of the extension member that is opposite the cross member. The cam arm includes a spring arm configured to engage with a locking pin coupled to the cabinet, a clearance hole configured to permit the cam arm to clear the locking pin when the pivoting handle is in the stored position, an aperture configured to permit a pivot pin to secure the cam arm to the cabinet, and a compression gap adjacent to the spring arm. The compression gap is configured to permit the spring arm to provide resistance to the pivoting handle during pivoting.
