Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing toner supply container mounting and conveying systems in printers and copiers face high friction and wear issues due to sliding mechanisms, making it difficult and costly to replace worn-out parts.
Innovation Solution
A linkage device comprising a transverse linkage with a rod body and jaw portion, and a longitudinal linkage rotatably coupled to the rod body, which converts sliding friction into rotating friction, reducing wear and enabling easier replacement of parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a sliding rail and sliding shaft mechanism is used for toner supply container mounting, then the container can be conveyed and mounted, but high friction occurs and key parts wear out quickly
Solution Approach 1:
The patent replaces the sliding rail and sliding shaft mechanism with a linkage mechanism consisting of a transverse linkage and a longitudinal linkage. This substitution transforms the high-friction sliding contact into a rotating joint system, significantly reducing wear on key parts while maintaining the toner container mounting and conveying function.
Solution Approach 2:
The invention changes the fundamental motion parameter from linear sliding to rotational movement. By using rotating joints in the linkage mechanism instead of sliding contacts, the friction characteristics are fundamentally altered, reducing wear and improving reliability of the mounting mechanism.
2Device complexity
If sliding friction is used in the mounting mechanism, then simple structure is achieved, but resistance is high and part wear increases
Solution Approach 1:
The patent substitutes the simple sliding mechanism with a linkage mechanism comprising transverse and longitudinal linkages connected by rotating joints. Although the structure becomes slightly more complex, the friction resistance is dramatically reduced by replacing sliding friction with rotational movement, achieving lower operational forces.
3Ease of repair
If high wear occurs in the lifting device, then frequent maintenance is needed, but complete assembly replacement is required which is costly
Solution Approach 1:
The patent segments the mounting mechanism into distinct linkage components (transverse linkage, longitudinal linkage, rotating joints) that can be independently replaced. This modular segmentation allows worn parts to be replaced individually rather than requiring complete assembly replacement, reducing maintenance costs and improving ease of repair while extending overall service life.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The linkage device effectively reduces resistance and extends the service life of the lifting device by minimizing wear, allowing for repeated installation of toner consumables without the need for full assembly replacement.
Implementation Method 1
A lifting device is required to lift the machine. The present invention converts sliding friction into rotating friction, which provides a smaller resistance to effectively reduce the post wear of the lifting device required by the machine.

AI summary
A linkage device for a toner supply container includes: a transverse linkage, which comprises a rod body and a jaw portion, wherein the jaw portion is connected to a front end of the rod body; and a longitudinal linkage, wherein a first end of the longitudinal linkage is rotatably coupled to the rod body of the transverse linkage. A mounting and conveying device for the toner supply container includes: the linkage device and a cover body, wherein a first connecting post and a third connecting post are arranged on a side face of the cover body; wherein a second end of the longitudinal linkage is rotatably fixed to the first connecting post, and a spring post is connected to the third connecting post by a tension spring. Such structure is well sealed and simple with less wear on the parts.
