Working Machine Overlapping Ground Projections for Continuous Bulk Loading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing material loading procedures for working machines often result in material being discharged outside the receptacles, especially when multiple machines are loaded simultaneously, requiring intermittent distribution to prevent spills, which is inefficient and can lead to material loss.
Innovation Solution
The design of working machines with overlapping circumference projections in their load receiving areas allows for continuous material discharge from a station without spills, enabling multiple machines to be loaded simultaneously with a low risk of material being discharged outside their receptacles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple working machines are loaded simultaneously from a discharge arrangement, then loading efficiency is improved, but material may be discharged outside the receptacles causing loss and mess
Solution Approach 1:
The patent applies dimensionality change by projecting the load receiving area circumference vertically onto the ground to create a circumference projection. This transforms a two-dimensional area boundary into a one-dimensional ground projection, enabling overlapping arrangements of multiple working machines while ensuring material discharged from above lands within receptacle boundaries. The vertical projection approach resolves the contradiction by allowing simultaneous loading of multiple machines without material loss.
Solution Approach 2:
The patent implements nesting by arranging working machines such that the circumference projection of one machine's load receiving area overlaps with another machine's circumference projection on the ground. This nested arrangement allows multiple machines to be positioned under a single discharge arrangement, enabling simultaneous loading while the overlapping projections ensure material discharge remains within receptacle boundaries, preventing material loss.
2Loss of substance
If intermittent distribution is used to prevent material discharge outside receptacles, then material loss is reduced, but loading speed decreases
Solution Approach 1:
The patent enables continuous material discharge by allowing multiple working machines to be arranged with overlapping circumference projections. This configuration permits a discharge arrangement to continuously discharge material onto multiple receptacles simultaneously without interruption or intermittent distribution. The continuous action maintains high loading speed while the overlapping projection geometry ensures material remains within receptacle boundaries, preventing loss.
3Device complexity
If working machines are arranged with non-overlapping circumference projections, then material discharge control is simplified, but the number of machines that can be loaded simultaneously is limited
Solution Approach 1:
The patent uses vertical projection onto the ground to simplify discharge control while increasing simultaneous loading capacity. By projecting the load receiving area circumference vertically, the system creates ground-based circumference projections that can overlap. This dimensional transformation allows multiple machines to be arranged with overlapping projections under a single discharge arrangement, increasing productivity while the projection-based control method remains simpler than intermittent distribution systems.

AI summary
The present invention relates to a working machine (10) comprising a receptacle portion (12) for accommodating load. The working machine is adapted to have a load receiving condition in which the receptacle portion (12) comprises an open load receiving area (14) outwardly delimited by a load receiving area circumference (16). The working machine (10) extends in at least a vertical direction (V) and the working machine (10) comprises a circumference projection (22) being a projection of the load receiving area circumference (16) in the vertical direction (V) onto a ground (24) on which the working machine (10) is located. The working machine (10) is such that it, in the load receiving condition, can assume a position relative to a second working machine (11) of the same type in which position the circumference projections (22, 23) of the two working machines (10, 11) at least partially overlap.
