Output Sheet Stacking Tray With Inclined Impact Absorber
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing output-sheet-stacking devices face issues with stacking failures due to the upper end of the impact absorbing part protruding from the rear wall, leading to variations in sheet stacking positions.
Innovation Solution
The device incorporates a tray with a rear wall and an impact absorbing part featuring an inclined surface that extends diagonally downward, allowing the sheet to be stacked with the front edge above the rear edge, and includes cushioning materials between ribs to absorb the impact, reducing noise and improving stacking consistency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the upper end of the impact absorbing part juts out from the rear wall surface, then the impact absorbing part can effectively receive the rear edge of the sheet, but stacking failures occur due to variations in sheet stacking positions
Solution Approach 1:
The impact absorbing part is designed with an inclined surface that extends diagonally downward from the rear wall, transitioning from a vertical protrusion to a diagonal configuration. This dimensional change allows the impact absorbing part to maintain contact with the rear edge of sheets while preventing stacking failures, as the inclined surface guides sheets to the correct stacking position.
Solution Approach 2:
The geometry of the impact absorbing part is modified by introducing an inclined surface with a specific angle relative to the rear wall. This parameter change (from vertical to diagonal orientation) optimizes both impact absorption and stacking position consistency, resolving the contradiction between effective impact absorption and precise stacking.
2Object-affected harmful factors
If the impact absorbing part is made to absorb sheet impact, then noise is reduced, but stacking failures occur when the upper end protrudes from the rear wall
Solution Approach 1:
By changing the impact absorbing part from a vertical protrusion to a diagonal configuration with an inclined surface, the design maintains noise reduction capabilities while eliminating stacking failures. The diagonal orientation ensures smooth sheet guidance without protrusions that could cause misstacking.
3Ease of operation
If the inclined surface of the impact absorbing part intersects the rear wall surface, then sheet movement is smoothed, but the structure becomes more complex
Solution Approach 1:
The inclined surface is designed with a specific angle parameter that optimizes sheet movement smoothness. By carefully selecting the angle and intersection geometry with the rear wall, the design achieves easy sheet guidance while maintaining relatively simple construction, balancing operational ease with structural complexity.

AI summary
An output-sheet-stacking device includes: a tray including a rear wall and disposed in a downward direction from an outlet through which a sheet is output, the tray allowing the sheet output from the outlet to be stacked on the tray with the sheet being in a position in which a front edge of the sheet is positioned in an upward direction from a rear edge of the sheet; and at least one impact absorbing part provided on the rear wall of the tray and configured to, while receiving the rear edge of the sheet stacked on the tray, absorb an impact caused by a hit of the sheet, the at least one impact absorbing part including an inclined surface extending diagonally downward as proceeding in an output direction of the sheet and intersecting a surface of the rear wall when viewed from a side.
