Belt Conveyor Device Grip Stability and Insertion Sliding Distance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing belt conveyor devices for image forming apparatuses face instability during gripping due to the placement of grip portions not corresponding to the center of gravity, leading to potential damage during mounting and increased sliding distance when electrical contact portions are positioned on the upstream side.
Innovation Solution
A belt conveyor device design with a first grip portion on one end and a second grip portion on the other end, where the electrical contact is placed on the second end, ensuring the center of gravity is within the range of both grip portions, and the second grip portion is positioned upstream of the center of gravity in the insertion direction to maintain stability and reduce sliding distance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the grip portion is provided on the downstream side to correspond to the center of gravity position, then the stability of gripping is improved, but the sliding distance from the electrical contact portion on the main body side to the belt conveyor device is increased
Solution Approach 1:
The belt conveyor device is divided into two separate grip portions: a first grip portion on the upstream side and a second grip portion on the downstream side. This segmentation allows the device to be held stably by positioning hands at different locations, with the downstream grip portion aligning with the center of gravity while the upstream grip portion keeps the sliding distance short.
Solution Approach 2:
The grip portions are arranged in the width direction (lateral dimension) rather than only in the insertion direction (longitudinal dimension). By providing grip portions at both ends in the width direction, the patent achieves stable gripping without increasing the sliding distance in the insertion direction.
2Stability of the object's composition
If the electrical contact portion is arranged on the upstream side to avoid the grip portion, then the grip stability is improved, but the sliding distance is increased making insertion difficult
Solution Approach 1:
The electrical contact portion is segmented from the grip portions by being positioned on the upstream side while grip portions are distributed at both upstream and downstream ends. This allows the electrical contact to avoid interference with the primary gripping action while the downstream grip portion maintains stability.
Solution Approach 2:
The first grip portion on the upstream side acts as an intermediary element that allows the electrical contact portion to be positioned upstream without compromising grip stability. The dual grip portion arrangement mediates between the electrical contact positioning and the center of gravity alignment.
3Ease of operation
If the grip portion is provided at the center of gravity position, then the operability is improved, but the electrical contact portion arrangement becomes constrained
Solution Approach 1:
The grip function is segmented into two separate portions rather than relying on a single central grip. This segmentation provides flexibility in arranging the electrical contact portion while maintaining operability through the downstream grip portion that aligns with the center of gravity.
Solution Approach 2:
The belt conveyor device is designed with multi-functionality: the first grip portion handles electrical contact alignment during insertion, while the second grip portion provides stable gripping during handling. This universal design accommodates both electrical contact requirements and ergonomic gripping needs.

AI summary
There are included a first grip portion provided on a first end side of a belt conveyor device, in a width direction intersecting a rotational direction of the belt, and a second grip portion and an electrical contact portion provided on a second end side of the belt conveyor device. A center of gravity position of the belt conveyor device is provided on a downstream side of a center of the belt conveyor device and a range where the center of gravity position of the belt conveyor device is provided in a range where the contact portion and the first grip portion are provided. The second grip portion is provided on an upstream side of the center of gravity position of the belt conveyor device in an insertion direction of the belt conveyor device.
