Toner Case Conveying Member Linkage Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing toner cases face issues with the design of the conveying member, where the large diameter agitating gear restricts the filling port location and size, leading to potential mold scratches during manufacturing and increased load on the conveying member due to toner weight or shocks, which can damage linked assembly portions.
Innovation Solution
A toner case design featuring a conveying member with a first and second attaching assembly and a linking assembly, where the linking assembly is slidable and rotates with both, preventing the attaching assemblies from disengagement and absorbing external forces, thus reducing load on linked portions and preventing damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the conveying member is structured by linking a plurality of members to improve ease of assembling, then the ease of assembly is improved, but the load on linked portions increases due to toner weight or shocks, possibly damaging the linked portion
Solution Approach 1:
The conveying member is divided into multiple independent members (first conveying member and second conveying member) that are linked together. Each member can be manufactured separately and then assembled, improving ease of assembly while distributing the load across multiple components rather than concentrating it on linked portions
Solution Approach 2:
The linking assembly is designed with a sliding mechanism that allows dynamic adjustment and absorption of external forces. The sliding structure enables the linking portions to move relative to each other, absorbing shocks and reducing the load transmitted through the links during operation or impact
2Manufacturing precision
If a metal mold is used to manufacture the conveying member with separate insert for coupling, then the manufacturing precision is improved, but the mold may be scratched when the insert is replaced
Solution Approach 1:
The coupling and conveying gear are integrated into a single mold as one piece, eliminating the need for separate inserts. This merging of components into a single molding operation prevents mold scratches from insert replacement while maintaining manufacturing precision through the unified mold structure
3Volume of moving object
If the conveying member is located mostly in the case body, then the structural compactness is improved, but a large load is applied to the conveying member due to toner weight or shocks
Solution Approach 1:
The conveying member is segmented into multiple parts distributed throughout the case body rather than concentrated in one location. This segmentation allows the toner weight and shock loads to be distributed across multiple components, reducing the force on any single portion while maintaining compact overall structure

AI summary
A toner case includes a case body, a cover, and a conveying member. The cover covers the outer surface of a wall at an end of the case body. The conveying member, including a first attaching assembly, a second attaching assembly and a linking assembly, is rotatably attached to the case body and feeds toner. The first attaching assembly is rotatably attached to the wall. The second attaching assembly is rotatably attached to a wall at the other end of the case body. One end and the other end of the linking assembly are respectively linked to the first attaching assembly and second attaching assembly. One end is slidable in the longitudinal direction of the conveying member. The linking assembly rotates together with the first and second attaching assemblies. The first attaching assembly engages the cover's inner surface, preventing the first attaching assembly from coming off the one-end wall.
