Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If plumbers lift toilets by hand, then the task can be completed, but the risk of injury increases and wastewater may spill
Solution Approach 1:
The patent introduces a lifting apparatus as an intermediary device between the plumber and the toilet. The apparatus includes a frame with legs, a lifting assembly with a threaded rod and collar, and a contact portion with hooks that engage the toilet. This intermediary mechanism allows the plumber to operate the lifting device remotely using the threaded collar, eliminating direct manual lifting and reducing injury risk and wastewater spillage.
2Adaptability or versatility
If existing lifting devices are used, then lifting capability is provided, but they are not suitable for light yet cumbersome objects like toilets
Solution Approach 1:
The patent designs a universal lifting apparatus that can handle various light yet cumbersome objects such as toilets, sinks, and bathtubs. The apparatus features adjustable legs with feet for stability, a versatile contact portion with hooks that can engage different object types, and a mobile design with wheels. This multi-functional design allows a single device to replace multiple specialized lifting tools.
Solution Approach 2:
The lifting apparatus incorporates dynamic elements including wheels on the frame for mobility, adjustable legs that can pivot and extend, and a threaded lifting mechanism that provides controlled motion. The contact portion with pivoting hooks can adapt its position and orientation. These dynamic features enable the device to adjust to different objects and workspace conditions, enhancing versatility.
3Ease of operation
If a lifting apparatus is introduced, then safety and control are improved, but the device complexity increases
Solution Approach 1:
The lifting apparatus employs a threaded rod and collar mechanism that allows the operator to self-adjust the lifting height and control the lifting speed by simply rotating the collar. The legs automatically stabilize the frame when extended, and the hooks self-adjust to engage the object. This self-service design reduces the need for complex control systems while maintaining ease of operation.
Solution Approach 2:
The apparatus is divided into functional segments: a mobile frame with wheels, adjustable stabilizing legs, a lifting mechanism with threaded rod and collar, and a contact portion with hooks. Each segment performs a specific function and can be independently adjusted or positioned. This segmentation allows the complex device to be operated through simple, localized actions at each segment rather than requiring complex coordinated control.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables safe and efficient lifting of toilets and similar fixtures, reducing the risk of injury and preventing wastewater spillage by providing precise control and mobility.
Implementation Method 1
The lifting component comprises a threaded rod, a threaded collar, a contact portion coupled to the threaded rod
Implementation Method 2
a lifting arm, a contact portion configured to engage an object to be lifted, and a lifting component, the contact portion functionally coupled to the at least one beam with the lifting component, the lifting component pivotally coupled to the at least one beam with the lifting arm
Implementation Method 3
the at least one of the frames further includes wheels for facilitating movement of the apparatus

AI summary
A lifting apparatus is disclosed that includes a first frame and a horizontally opposed second frame interconnected by at least one beam at their top portions. A lifting assembly is pivotally mounted to the beam between the frames and includes a lifting arm, a contact portion for engaging an object, and a lifting component. The contact portion is connected to the beam via the lifting component, which is also pivotally connected to the beam through the lifting arm. The configuration allows for selective actuation of the lifting arm to raise and lift an object independently of the vertical movement facilitated by the lifting mechanism, providing improved control and flexibility in lifting operations.
