Double-Telescoping Leg Leveler for Extended Height Adjustment Range
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional appliance leveling devices have limited height adjustment ranges and are bulky, making them inefficient for accommodating uneven surfaces and optimizing appliance positioning.
Innovation Solution
A double-telescoping leg leveler with interlocking thread patterns and stop protrusions allows for increased height adjustment, featuring a central member that couples the foot and upper member, ensuring stability and ease of assembly through inclined internal threads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If a single threaded shaft leveling device is used, then the structure is simple, but the height adjustment range is limited and the structure is bulky
Solution Approach 1:
The patent employs a double-telescoping mechanism where the central member is received within the upper member, and the foot is received within the central member. This nested arrangement allows multiple telescoping segments to provide extended height adjustment range while maintaining a compact retracted profile, directly resolving the contradiction between adjustment range and structural bulkiness.
Solution Approach 2:
The leveling device is divided into three distinct segmental components: an upper member with a post, a central member with threaded engagement features, and a foot member. Each segment can independently telescope relative to the others through threaded engagement, enabling extended adjustment range without requiring a single bulky structure.
2Volume of moving object
If a single threaded shaft leveling device is used, then the manufacturing is simple, but the structure is bulky and occupies more space
Solution Approach 1:
The telescoping segments nest within each other when retracted, significantly reducing the overall device volume compared to a single-threaded shaft design. The nested configuration allows the device to occupy minimal space when not in use, while still providing extended adjustment capability when needed.
Solution Approach 2:
By segmenting the device into modular components with standardized threaded engagement features, the patent reduces the volume required for each individual component while maintaining overall functionality. The segmented design allows for more efficient space utilization compared to a monolithic single-threaded shaft structure.
3Adaptability or versatility
If conventional leveling legs are used, then the structure is unitary and simple, but the adjustment range is limited
Solution Approach 1:
The double-telescoping mechanism with nested segments provides substantially increased adjustment range compared to conventional unitary leveling legs. Each telescoping segment contributes to the overall adjustment capability, allowing the device to adapt to a wider variety of floor surface conditions and appliance height requirements.
Solution Approach 2:
The patent transitions from a static unitary structure to a dynamic telescoping system where segments can extend and retract relative to each other. This dynamic capability is achieved through threaded engagement features that allow controlled movement, providing enhanced adaptability while maintaining structural integrity through the interlocking segmental design.
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
The double-telescoping leg leveler provides a robust, space-saving design that effectively levels appliances on uneven surfaces, offering a wider height adjustment range and improved stability, facilitating easier installation and adjustment.
Implementation Method 1
The post is externally threaded. The first internal thread is rotatably engaged with the post to extend the central member away from the mounting portion when lengthening said leveler, and to retract the post into the central member when shortening said leveler. The second internal thread is rotatably engaged with the external thread of the central member to extend the foot away from the mounting portion when lengthening said leveler, and to retract the central member into the foot when shortening said leveler.

AI summary
A double-telescoping leg leveler is provided having an upper member, a central member, and a foot. The upper member is adapted to attach the leveler to an appliance. The central member includes an external thread pattern and is adapted to rotatably couple the foot to the upper member. The internal thread patterns of the foot and central member include a distal end that is shaped to enable a retraction of the leveler. The internal thread patterns of the foot and the central member are also configured to prevent the foot and central member from becoming disengaged from the leveler when extending the leveler.
