Solution Overview
Problem
Existing mobile, freestanding kitchen appliances lack efficient mechanisms for easy relocation and stable positioning on various surfaces, particularly on inclined or uneven terrain, compromising ease of use and stability.
Innovation Solution
The kitchen appliance features a base with non-slip and sliding feet, where the non-slip foot is positioned behind the center of gravity to facilitate easy lifting and movement, while the sliding foot ensures stability on varying surfaces, and interchangeable caps enhance slip resistance or sliding properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the kitchen appliance has all non-slip feet for stable positioning, then stability on inclined surfaces is improved, but difficulty in relocation increases
Solution Approach 1:
The patent applies different foot characteristics to different locations: non-slip feet are positioned at the front and rear of the base to provide stability, while a sliding foot is positioned at the side to facilitate easy relocation. This local differentiation allows the appliance to simultaneously achieve stable positioning on inclined surfaces and easy relocation by the user.
2Stability of the object's composition
If the center of gravity is positioned at the front of the base for stable operation, then operational stability is improved, but effort required for lifting increases
Solution Approach 1:
The patent creates an asymmetric weight distribution by positioning the center of gravity in the rear half of the base rather than at the center or front. This asymmetric positioning, combined with the strategic placement of a sliding foot at the side behind the center of gravity, creates a lever advantage that reduces the effort required for lifting while maintaining operational stability during use.
3Ease of operation
If the sliding foot is positioned at the front of the base for easy lifting, then relocation effort is reduced, but stability on uneven surfaces deteriorates
Solution Approach 1:
The patent segments the base support system into multiple specialized feet: non-slip feet at the front and rear for stability, and a sliding foot at the side for relocation. This segmentation allows each foot to perform its specific function optimally - the sliding foot facilitates easy lifting and movement without compromising the stability provided by the non-slip feet positioned at strategic locations.
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 easy relocation and secure positioning on different surfaces, enhancing user convenience and stability by minimizing effort required for movement and preventing accidental slipping.
Implementation Method 1
The non-slip base of a non-slip foot can be made of a non-slip material such as an elastomer or another plastic with a high coefficient of friction compared to POM or PE-UHMW. In contrast, a non-slip base of a sliding foot can be made of a low-friction material such as POM, glass fiber-reinforced POM, or PE-UHMW.
