Solution Overview
Problem
Existing image forming apparatuses with cassette storage systems require complex linking mechanisms and numerous components, increasing costs and assembly time due to the need for additional components and intricate mechanisms to secure the cassette during attachment and detachment.
Innovation Solution
A sheet storage apparatus with a moving unit comprising a regulation member and an extending member bonded using adhesive or double-sided tape, which allows for secure sheet positioning and attachment without the need for additional fastening members, reducing complexity and cost.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a linking mechanism is used to move the mobile carriage in conjunction with cassette attachment and detachment, then the cursor intensity and impact resistance are improved, but the number of components and assembling man-hours are increased
Solution Approach 1:
The patent extracts the linking mechanism from the system, eliminating the mobile carriage and its connection to the cassette attachment/detachment mechanism. The cursor is made stationary while maintaining its regulatory function through a different structural approach, thereby removing the complexity associated with the linking mechanism.
Solution Approach 2:
The patent segments the cursor function from the mobile carriage system. Instead of moving the entire carriage with the cassette, only the necessary regulatory elements are retained in a stationary position, separating the regulatory function from the transport function.
2Reliability
If a linking mechanism is used to move the mobile carriage in conjunction with cassette attachment and detachment, then the cursor intensity and impact resistance are improved, but the assembling man-hours and cost are increased
Solution Approach 1:
The patent removes the linking mechanism that connected the mobile carriage to the cassette system, eliminating the need for complex assembly procedures while maintaining reliability through a simplified stationary cursor design that inherently withstands impact forces.
3Strength
If fastening members are used to secure the regulation member and extending member, then the bonding strength is improved, but the device complexity and cost are increased
Solution Approach 1:
The patent replaces the mechanical fastening system (screws, clips, or other fastening members) with a chemical bonding system using adhesive. This substitution maintains the necessary bonding strength while eliminating the complexity of mechanical fastening components and their assembly procedures.
Solution Approach 2:
The patent changes the bonding method from mechanical (fastening members) to chemical (adhesive), altering the fundamental parameter of how the regulation member and extending member are connected. This parameter change achieves equivalent or superior bonding strength with reduced complexity.
