Sheet Cooling Device Restricting Member Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sheet cooling devices and image forming systems face the issue of the tip resistant member being forgotten in the standby position, leading to potential tilting when the cooling unit is drawn out, due to the weight imbalance.
Innovation Solution
A sheet cooling device with a restricting member that can be positioned in two states: a restricted position to prevent the cooling unit from being drawn out, and a tip resistant position where it opposes the installation surface, ensuring the device remains stable during maintenance and operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the tip resistant member is stored in a standby position hidden in the floor when not in use, then the device maintains a clean appearance and compact structure, but there is a risk that users forget to set it in the functional position when needed
Solution Approach 1:
The restricting member is merged with the cooling unit to form an integrated assembly. The restricting member includes a limiting portion that mechanically interferes with the cooling unit's movement, ensuring that the cooling unit cannot be drawn out unless the restricting member is properly positioned. This integration ensures that the restricting member is always accounted for and cannot be forgotten, as it is physically connected to the cooling unit that users interact with during maintenance operations.
2Ease of operation
If the cooling unit is drawn out of the device during maintenance, then users can access and maintain the cooling components, but the weight of the cooling unit may cause the sheet cooling device to tilt if the restricting member is not properly positioned
Solution Approach 1:
The restricting member is designed to preemptively prevent the cooling unit from being drawn out beyond a safe position. The limiting portion of the restricting member creates a mechanical barrier that stops the cooling unit's movement before it can cause the device to tilt. This preliminary anti-action ensures that even if users forget to position the restricting member, the mechanical interference prevents the instability condition from occurring.
Solution Approach 2:
The restricting member is pre-positioned in a restricted position that limits the cooling unit's drawout distance. This preliminary positioning ensures that the cooling unit can be accessed for maintenance while maintaining device stability. The restricting member must be moved to a release position before the cooling unit can be fully drawn out, ensuring that users are aware of the restricting member's presence and function.
3Ease of operation
If the restricting member is made movable between restricted and release positions, then the cooling unit can be accessed for maintenance, but the mechanism becomes more complex
Solution Approach 1:
The restricting member is designed as a movable component that can transition between a restricted position (where it limits cooling unit movement) and a release position (where it allows full drawout). This dynamic design enables the restricting member to adapt to different operational states: limiting movement during normal operation and allowing movement during maintenance. The movability is achieved through a simple mechanical linkage that users can manually operate, balancing functionality with structural simplicity.
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 solution effectively reduces the likelihood of forgetting to set the restricting member to the tip resistant position, thereby preventing the device from tipping over when the cooling unit is drawn out, ensuring stability and safety.

AI summary
A sheet cooling device includes a main assembly, a cooling unit, drawable out of the main assembly with respect to a drawing direction and a restricting member. The restricting member is positionable in a first position where the cooling unit is restricted from drawing out of the main assembly and in a second position lower than the first position where said restricting member opposes to an installation surface on which the sheet cooling device is installed.
