Solution Overview

Problem

Users face difficulties in determining the appropriate amount of shaking force required to properly disperse print material in a print material container, which affects the efficiency and waste reduction in image forming apparatuses.

Innovation Solution

A print material container equipped with a detecting member that senses the shaking force and provides feedback when it exceeds a predetermined threshold, ensuring adequate dispersion of print material before and after its life cycle.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If users manually determine the appropriate shaking force to disperse print material, then they can control the dispersion process, but it increases operational complexity and reduces efficiency due to uncertainty about the required shaking force

Engineering Contradiction:
Improveease of operationVSAvoidproductivity
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The patent applies the feedback principle by incorporating a detecting member that senses the shaking force applied to the container and provides feedback to the user. This allows users to understand whether they are applying sufficient shaking force to disperse the print material, eliminating guesswork and improving both ease of operation and productivity.

Inventive Principle:
Principle #23Feedback

2Stability of the object's composition

If sufficient shaking force is applied to disperse print material, then print material dispersion is improved, but energy consumption increases

Engineering Contradiction:
Improvedispersion uniformityVSAvoidenergy consumption
Core Design Contradiction:
Stability of the object's compositionVSUse of energy by moving object

Solution Approach 1:

The detecting member provides real-time feedback on the shaking force applied, allowing users to stop shaking once the desired dispersion uniformity is achieved. This prevents excessive energy consumption while ensuring adequate dispersion of the print material.

Inventive Principle:
Principle #23Feedback

3Measurement precision

If a detecting member is added to sense shaking force, then measurement precision of shaking force is improved, but device complexity increases

Engineering Contradiction:
Improveshaking force measurement precisionVSAvoiddevice complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The detecting member is integrated into the existing container structure and utilizes the natural shaking motion to generate signals. The system serves itself by using the shaking action (which is already necessary for dispersion) to simultaneously achieve both dispersion and measurement, minimizing additional complexity.

Inventive Principle:
Principle #25Self-service
