Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid applying devices experience a decrease in liquid supply to the fixing belt due to deformation and changing pressure, leading to increased torque and wear of the belt, especially at the end portions where oil application is insufficient.
Innovation Solution
A liquid applying device with a plate-shaped impregnation member and a support member, where the end portion of the impregnation member is in contact with the fixing belt at an angle, supported by a leaf spring that maintains pressure and prevents deformation, ensuring consistent oil supply and reduced wear.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a plate-shaped impregnation member is supported up to an intermediate portion, then the structure is simple, but the liquid supply amount decreases due to deformation and changing pressure
Solution Approach 1:
A support member is introduced as an intermediary element between the impregnation member and the supporting structure. This support member extends in the width direction of the circulation member and supports the impregnation member at multiple positions, preventing deformation while maintaining consistent liquid supply pressure. The support member acts as a mediator that transmits support force uniformly across the impregnation member without requiring complex support structures.
2Device complexity
If the impregnation member is not properly supported, then the device structure is simpler, but the torque required for belt movement increases due to increased wear
Solution Approach 1:
The support member serves as an intermediary that prevents deformation of the impregnation member, ensuring consistent liquid supply and reducing wear between the circulation member and impregnation member. By maintaining proper contact and pressure, the support member reduces friction and wear, thereby decreasing the torque required for belt movement without requiring complex support structures.
3Stability of the object's composition
If the impregnation member deforms, then the structure adapts to wear, but the liquid supply pressure changes and supply amount decreases
Solution Approach 1:
The support member acts as an intermediary that counteracts deformation forces on the impregnation member. By supporting the impregnation member at multiple positions along its width, the support member maintains the structural integrity and shape of the impregnation member, ensuring consistent liquid supply pressure and preventing the decrease in liquid supply amount that would result from deformation.
4Stability of the object's composition
If the support member extends in the width direction, then the impregnation member is stabilized, but the support structure becomes more complex
Solution Approach 1:
The support member is designed with local quality by extending specifically in the width direction of the circulation member where deformation occurs. This targeted support approach stabilizes the impregnation member at critical positions without requiring comprehensive complex support structures throughout the entire device. The support member's extension in the width direction provides localized stability where it is most needed.

AI summary
A liquid applying device includes a circulation member, an impregnation member, and a support member. The circulation member is configured to circulate in a predetermined direction. The impregnation member is formed in a plate shape. The impregnation member is impregnated with a liquid. The impregnation member is in contact with the circulation member at an end portion thereof in a direction intersecting with a circulating direction of the circulation member so as to apply the liquid to the circulation member. The support member supports a portion including an end portion side of the impregnation member, at an opposite side of the circulation member in a state where the end portion of the impregnation member is in contact with the circulation member.
