Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid stirring methods, such as rotating the storage portion of liquid, are inefficient in dispersing sedimented substances like pigment ink or metallic ink in printing apparatuses.
Innovation Solution
A liquid stirring apparatus with a storage unit that rotates at multiple stop positions, each with different stop times, to enhance the dispersion of sedimented substances.

Engineering Contradiction Analysis
1Productivity
If the storage portion of liquid is simply rotated, then the apparatus structure is simple, but the stirring efficiency is insufficient
Solution Approach 1:
The storage portion implements dynamic rotation with variable stop positions and stop times rather than simple continuous or uniform rotation. The rotation includes multiple stop positions (first stop position with first stop time, second stop position with second stop time) that create varying motion patterns to enhance stirring efficiency while maintaining a relatively simple apparatus structure.
Solution Approach 2:
The rotation operation incorporates periodic stopping at multiple positions with different stop times, creating a periodic motion pattern. This periodic action with varying intervals and positions improves liquid circulation and sediment dispersion effectiveness compared to uniform rotation, addressing the contradiction between simplicity and efficiency.
2Productivity
If the storage portion rotates with varying stop times at multiple positions, then the stirring efficiency is improved, but the control complexity increases
Solution Approach 1:
The system changes operational parameters (stop positions and stop times) during the rotation cycle. By varying the stop time at different stop positions (first stop time at first stop position, second stop time at second stop position), the system achieves better dispersion effectiveness without requiring complex mechanical structures, only parameter variation in the control logic.
Solution Approach 2:
The control unit manages the rotation operation with feedback on the storage portion's position and state, adjusting stop positions and stop times optimally. This feedback mechanism allows the system to achieve effective stirring with a relatively simple control structure by making real-time adjustments based on operational conditions.

AI summary
A liquid stirring apparatus comprises storage means for storing a liquid; and driving means for performing a rotation operation of rotating the storage unit. The rotation operation includes a stop operation of stopping rotation of the storage means at a plurality of stop positions. The plurality of stop positions include a first stop position at which a stop time is a first time, and a second stop position at which the stop time is a second time different from the first time.
