Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sheet storage devices lack effective mechanisms to stabilize and regulate the positional deviation of sheets during feeding, which can lead to misalignment and printing errors in image forming apparatuses.
Innovation Solution
A sheet storage device equipped with a regulation cursor that can reciprocate horizontally and is held in place by a hold mechanism, utilizing a guide shaft and stopper system to generate frictional resistance and maintain the cursor's position, ensuring accurate sheet alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the regulation cursor is allowed to reciprocate freely to regulate sheet position, then sheet alignment flexibility is improved, but positional stability deteriorates
Solution Approach 1:
The regulation cursor is designed to be dynamically adjustable during sheet loading, allowing free reciprocation for positioning. Once positioned, the hold mechanism engages to maintain stability. This dynamic transition from movable to fixed state resolves the contradiction between alignment flexibility and positional stability.
Solution Approach 2:
The hold mechanism acts as an intermediary between the regulation cursor and the sheet storage device frame. It provides the necessary stabilization function without interfering with the cursor's ability to move freely during the positioning phase, thus resolving the contradiction between movability and stability.
2Stability of the object's composition
If the hold mechanism uses frictional resistance to restrict cursor movement, then positional stability is improved, but ease of operation deteriorates
Solution Approach 1:
The hold mechanism transitions from a non-restrictive state during positioning to a restrictive state for maintaining position. The frictional resistance is dynamically engaged only when needed for stability, allowing easy adjustment during positioning while providing firm holding during storage.
Solution Approach 2:
The frictional resistance parameter is changed from low (during positioning) to high (during holding) through the engagement of the hold mechanism. This parameter change allows the system to easily accommodate both the need for easy adjustment and firm stabilization at different operational stages.
3Reliability
If the stopper is designed to incline on a fulcrum to generate friction, then holding reliability is improved, but device complexity increases
Solution Approach 1:
The fulcrum acts as an intermediary element that enables the stopper to generate frictional resistance through inclination. This simple mechanical intermediary provides reliable holding without requiring complex actuation systems, sensors, or multiple components.
Solution Approach 2:
The hold mechanism is designed to be self-activating through the natural inclination of the stopper on its fulcrum. The frictional resistance is generated automatically by the mechanical configuration without requiring external power sources, control systems, or complex mechanisms, thus achieving reliability with minimal complexity.

Implementation Method 1
an inner edge of the guide hole contacts the guide shaft so as to generate frictional resistance, which restricts movement of the regulation cursor with the stopper

AI summary
A sheet storage device includes a regulation cursor and a hold mechanism. The hold mechanism includes a guide shaft, and a stopper having a guide hole in which the guide shaft is inserted, and being capable of reciprocating with the regulation cursor. When the stopper is inclined to one side, movement of the regulation cursor is restricted. When the stopper is raised to the other side, movement of the regulation cursor is enabled. The stopper has a contact part that contacts the regulation cursor, so as to restrict the stopper from inclining to the other side, when the regulation cursor is enabled to move.
