Casket Loading Tracks with Pivotable Flaps for Hearse Space Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coffin loading devices in funeral vehicles face challenges in efficiently transporting multiple coffins due to limited space, particularly around wheel arches, leading to uncomfortable loading and unloading and inefficient use of storage space, with previous solutions either compromising on support or requiring costly and complex guide devices.
Innovation Solution
A coffin loading device with pivotable track flaps that can be angled between +/- 45 degrees to the longitudinal direction, allowing full support for coffins and unhindered access to storage spaces, eliminating the need for additional guide devices and optimizing space utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If fixed outer tracks are used to transport two adjacent coffins above wheel arches, then the loading width is sufficient and multiple coffins can be transported, but the coffin is exposed at the sides and not supported during loading and unloading
Solution Approach 1:
The patent applies the dynamics principle by making the outer tracks longitudinally movable instead of fixed. The outer tracks can move along guide devices to accommodate the loading and unloading process, providing full support to the coffin while maintaining sufficient loading width above the wheel arches
2Ease of operation
If outer tracks are mounted in a longitudinally movable manner to fully support the coffin, then the comfort of loading and unloading is improved, but additional guide devices are required which increase device complexity and reduce loading height
Solution Approach 1:
The patent applies the universality principle by designing the outer tracks to serve multiple functions: they provide structural support for the coffin, enable longitudinal movement for loading/unloading, and simultaneously act as their own guide devices. The outer tracks are guided by the inner tracks and the vehicle structure, eliminating the need for separate guide devices
3Ease of operation
If guide devices for movable outer tracks are installed, then full support during loading is achieved, but access to storage spaces adjacent to wheel arches is blocked
Solution Approach 1:
The patent applies the segmentation principle by dividing the track system into inner and outer tracks with distinct functions. The inner tracks remain fixed to maintain storage space access, while the outer tracks are movable to provide support during loading. This segmentation allows the system to achieve full support without blocking storage spaces
4Ease of operation
If the loading track structure is raised to accommodate movable outer tracks, then full coffin support is achieved, but the loading height is reduced
Solution Approach 1:
The patent applies the dimensionality change principle by utilizing the longitudinal dimension for track movement instead of raising the entire structure vertically. The outer tracks move longitudinally along guide devices while maintaining their original height position, providing full support without reducing loading height
