Movable bearing device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional mini karaoke booths lack flexibility due to their fixed positioning and weight, making them difficult to move and adjust according to changing space needs.
Innovation Solution
A movable bearing device with a base, casters, and foot pads that can be adjusted between two positions, allowing for either ground support or caster-based movement, enhancing flexibility and ease of handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the mini karaoke booth is placed directly on the ground with certain weight, then it has good stability and support effect, but it becomes difficult to move and lacks flexibility
Solution Approach 1:
The patent applies the dynamics principle by making the support system adjustable between two states: a stationary state where foot pads contact the ground for stability, and a movable state where casters contact the ground for ease of movement. The foot pads are movable relative to the base between a first position (contacting ground) and a second position (not contacting ground), allowing dynamic transition between stability and mobility.
2Strength
If the mini karaoke booth is constructed with certain weight, then it has good support effect, but it requires suitable handling equipment for moving
Solution Approach 1:
The patent resolves this contradiction by incorporating casters that can contact the ground when foot pads are retracted to their second position. This allows the heavy booth to be moved easily by rolling on the casters rather than requiring handling equipment, while maintaining structural strength through the weighted base construction.
3Stability of the object's composition
If the mini karaoke booth is placed directly on the ground, then it is stable, but it cannot be adjusted according to changing space needs
Solution Approach 1:
The patent applies dynamics by enabling the booth to transition between a fixed stationary position (foot pads on ground) and a mobile position (casters on ground). This dynamic capability allows the booth to be relocated to different positions in the space according to changing needs, while maintaining stability when positioned.
Solution Approach 2:
The patent applies universality by designing a support system that performs multiple functions: the foot pads provide stable ground contact for stationary operation, while the casters enable easy relocation when needed. This multi-functional design allows the same booth to adapt to both stable operation and relocation scenarios.
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 device can be easily moved when needed and securely anchored when required, providing flexibility and ease of use by switching between two usage modes.
Implementation Method 1
The casters are attached to the bottom of the base and protruded from the bottom of the base
Implementation Method 2
The screw of each of the foot pads is inserted into one of the top holes of the top plate and screwed to one of the threaded holes of the support frame

AI summary
A movable bearing device includes a base, a plurality of casters, and a plurality of foot pads. The casters are provided on the bottom of the base. The foot pads are movably connected to the bottom of the base in a way that the foot pads are moved upwards and downwards with respect to the base. When the foot pads are moved downwards until their bottom surfaces each have a height equal to or lower than the bottom edges of the casters, the movable bearing device is supported on the ground by means of the foot pads, such that the movable bearing device cannot be moved. When the foot pads are moved upwards until their bottom surfaces each have a height higher than the bottom edges of the casters, the movable bearing device can be moved by means of the casters so as to facilitate the handling work.
