Movable Stand Stopper Switching for Shortened Use Positions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing movable stands require complex operations to switch between normal and shortened use positions, necessitating individual adjustment of stoppers.
Innovation Solution
Incorporation of a mode switching unit with a second stopper and a switching lever that allows for integrated switching between protruded and retracted states, coupled with a switching drive unit that drives multiple levers simultaneously using a simple linear drive mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If individual stopper mounting positions are changed to switch between normal and shortened use positions, then the stands can expand to different configurations, but the operation becomes complicated
Solution Approach 1:
Multiple stoppers are integrated into a single movable component that can be simultaneously positioned to engage with multiple support columns. This merging of individual stopper adjustments into one unified mechanism allows configuration switching without complex individual adjustments, resolving the contradiction between adaptability and ease of operation
Solution Approach 2:
The movable component serves multiple functions: it acts as a stopper for normal use position, can be repositioned to serve as a stopper for shortened use position, and provides integrated control for multiple floor stands. This multi-functionality enables configuration switching while maintaining simple operation
2Adaptability or versatility
If stoppers are repositioned individually while stored in storage position, then switching between normal and shortened use position modes is possible, but the operation becomes complicated
Solution Approach 1:
The adjustment procedure for multiple stoppers is merged into a single operation by providing a movable component that can be repositioned once to simultaneously adjust all stoppers. This eliminates the need for individual repositioning steps while maintaining the ability to switch between modes
3Length of moving object
If the attachment position of the stopper is changed to achieve shortened use position, then the length in front and back direction is shortened, but the operation to change positions becomes complicated
Solution Approach 1:
The position changing operation for achieving shortened use position is simplified by merging multiple stopper adjustments into a single movable component that can be repositioned once. This maintains the ability to achieve different lengths while eliminating complicated operation

AI summary
Movable stands include a plurality of floor stands, and a plurality of leg parts. The leg parts include a first stopper that allows the floor stand and the floor stand one step below to move forward in conjunction with each other to a state of being deviated in a stepped form, and a second stopper that allows the floor stands of the set to move forward in conjunction while being aligned in an up and down direction. The movable stands include a mode switching unit that switches the second stopper between a protruded state and a retracted state, and a switching drive unit. In the storage position, a plurality of sets of mode switching units are integrally driven in conjunction with driving of the switching drive unit to switch the plurality of sets of second stoppers between the protruded state and the retracted state.
