Electric shelf
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric shelves are unstable during rising or descending, leading to insecurity and increased installation costs, while also occupying valuable space due to fixed configurations.
Innovation Solution
An electric shelf design featuring a column mounted on the wall with a slidable component and a linear driving device, allowing the shelf board to move vertically along the column, reducing friction and enhancing stability, with a simpler and safer installation process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a pulley and motor are employed to achieve rising and declining of a ceiling type shelf, then the shelf can be raised and lowered, but instability during rising or declining causes the shelf to waggle and results in insecurity
Solution Approach 1:
The patent replaces the traditional pulley-motor mechanical system with a linear driving device that directly actuates the slidable component along the column. This substitution eliminates the intermediate pulley mechanisms that cause instability and wagging, providing more reliable and stable shelf movement while maintaining ease of operation through motor control.
2Ease of operation
If a ceiling type shelf is designed with ropes and pulleys, then rising and declining is achieved, but installation becomes difficult and costs increase
Solution Approach 1:
The patent segments the shelf system into modular components: a fixed column mounted on the wall, a slidable component that moves along the column, and a shelf board component connected to the slidable component. This segmentation allows for simpler installation compared to traditional pulley systems, as each component can be independently mounted and assembled, reducing installation complexity and cost.
3Ease of operation
If a fixed shelf is mounted at a lower height for easier access, then accessibility is improved, but more usable home space is occupied
Solution Approach 1:
The patent transforms the fixed shelf into a dynamic system where the shelf board component can move vertically along the column. Users can lower the shelf to access items at a convenient height, then raise it back up to save space when not in use. This dynamic capability allows the shelf to adapt between accessibility and space-saving modes, resolving the contradiction between easy access and space occupation.
4Area of stationary object
If a fixed shelf is mounted at a higher height to save space, then occupied space is reduced, but difficulty in accessing placed items increases
Solution Approach 1:
The patent enables the shelf to dynamically adjust its height along the vertical column. When space saving is needed, the shelf can be positioned at a higher location. When accessibility is required, the shelf can be lowered to a more convenient height. This dynamic positioning capability allows the system to switch between space-saving and accessibility modes as needed.
