Sheet Storage Device with Weight-Responsive Movable Box
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Sheet storage devices face misalignment and disarray due to varying drop heights as sheets pile up, leading to increased costs and operational inefficiencies from the need for periodic realignment and potential damage to sheets.
Innovation Solution
A sheet storage device with a movable storage box that adjusts its position based on the weight of stacked sheets, using a spring mechanism to maintain a consistent falling distance and prevent tilting, allowing for precise stacking and storage without a detection sensor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If sheets are stacked in the storage section, then the stacking position rises, but the drop height from ejection section to storage section changes causing misalignment
Solution Approach 1:
The storage section is designed to move downward automatically in response to the increasing weight of stacked sheets. This dynamic adjustment maintains a constant drop height from the ejection section to the storage section, ensuring that sheets consistently land at the same position regardless of how many sheets are already stacked. The movable storage section eliminates misalignment by adapting its position to the accumulation of sheets.
2Device complexity
If the storage section is fixed, then the structure is simple, but the stacking position varies causing sheets to be stored in disarray
Solution Approach 1:
The storage section transitions from a fixed structure to a dynamically movable one that responds to sheet weight. This allows the storage section to automatically adjust its position downward as sheets are stacked, maintaining consistent stacking conditions and preventing disarray while preserving structural simplicity.
3Device complexity
If the drop height varies, then no adjustment mechanism is needed, but sheets become misaligned and may be damaged
Solution Approach 1:
The storage section automatically adjusts its position downward in response to the weight of stacked sheets, maintaining a constant drop height. This dynamic adjustment prevents sheet misalignment and damage without requiring complex external control systems, sensors, or active adjustment mechanisms.
Solution Approach 2:
The storage section self-adjusts its position based on the weight of sheets it contains, automatically compensating for the rising stacking position. This self-service mechanism eliminates the need for external detection sensors or control systems to maintain proper stacking conditions.
