Canopy Document Storage for Working Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing storage apparatus on working vehicles, particularly power shovels, obstructs getting-on/off motions and narrows front visibility, and when the lid fails to close, it blocks front visibility, hindering work operations.
Innovation Solution
A storage apparatus with a frame and lid attached to the canopy's ceiling, where the lid hinges to the right wall and arcs to open/close, ensuring the entrance remains clear and visibility is maintained, even if the lid hangs due to a failure, with a holding portion on the lid to secure documents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the storage apparatus is arranged at a central position close to the front part in the ceiling part, then documents can be stored in the canopy, but the storage apparatus becomes an obstacle to getting-on/off motions and narrows front visibility
Solution Approach 1:
The storage apparatus is repositioned from a central front location to the right side of the vehicle body, utilizing the lateral dimension to resolve the conflict between storage availability and operator accessibility. This spatial reconfiguration eliminates obstruction during getting-on/off motions while preserving document storage functionality.
2Reliability
If the storage apparatus is arranged at a central position close to the front part, then documents can be stored, but front visibility is narrowed
Solution Approach 1:
The storage apparatus is relocated to the right side of the vehicle body, utilizing the lateral dimension to resolve the conflict between storage availability and operator visibility. This spatial reconfiguration eliminates obstruction to front visibility while preserving document storage functionality.
3Reliability
If the lid portion is not capable of being closed due to failure or defect, then the storage function is compromised, but the lid portion hangs down and blocks front visibility
Solution Approach 1:
The lid portion is designed to be separable from the storage apparatus body. When failure or defect occurs preventing proper closure, the lid can be completely removed from the vehicle, eliminating the hazard of it hanging down and blocking front visibility while the storage function remains operational.
4Volume of moving object
If documents are stored below the seat, then space utilization is improved, but it is difficult to manage space for battery and control equipment
Solution Approach 1:
The storage apparatus utilizes the vertical dimension of the canopy ceiling, moving document storage from the horizontal space below the seat to the overhead space. This reconfiguration frees up the area below the seat for battery and control equipment while maintaining efficient space utilization through vertical placement.
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
Prevents obstruction during getting-on/off, secures front visibility, allows easy document retrieval, and prevents damage from rain and vibrations, while optimizing space for battery and control equipment below the seat.
Implementation Method 1
a left end turns so as to draw an arc between a position of the left wall portion of the frame and a position in a lower direction of the right wall portion to open/close the opening
