Solution Overview

Problem

Existing delivery vehicles face challenges in securing and locking goods efficiently, especially for containers smaller than ISO standard, which are prone to water and dirt ingress, and are not suitable for narrow streets.

Innovation Solution

An embedded system with a support and fixing foot that integrates a locking mechanism, allowing secure attachment to a locking system, is designed to be watertight and compatible with various locking systems, featuring a detachable design for easy replacement and reduced material usage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a flatbed delivery vehicle is used with individual securing methods (straps, chains, padlocks), then access to goods is easy, but each item must be secured individually which is time-consuming

Engineering Contradiction:
ImproveAccess to goodsVSAvoidTime for securing goods
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The patent combines multiple individual securing operations into a single integrated locking action. The locking system with locking members can secure multiple items or containers simultaneously through one locking operation, eliminating the need to individually strap, chain, or padlock each item while maintaining easy access through the same integrated mechanism

Inventive Principle:
Principle #5Merging (Combining)

2Reliability

If an enclosed storage area is used, then access to goods is more secure, but it is generally less convenient and not always suitable for deliveries on narrow streets

Engineering Contradiction:
ImproveSecurity of goodsVSAvoidConvenience of access
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent segments the enclosed storage area into modular containers or compartments that can be individually accessed and secured. This allows the storage space to maintain security through enclosed structure while enabling convenient access to specific items without needing to move entire contents, and the modular design adapts to narrow street constraints

Inventive Principle:
Principle #1Segmentation

3Reliability

If locking systems with locking members are used, then goods can be secured, but existing systems allow water and dirt to enter through openings in corner fittings

Engineering Contradiction:
ImproveSecuring of goodsVSAvoidWater and dirt ingress
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent extracts the locking members from openings in corner fittings and relocates them to a separate locking system structure. This separation allows the corner fittings to be designed as solid, watertight structures while the locking members are positioned in a dedicated locking system that does not compromise the waterproofing integrity of the container corners

Inventive Principle:
Principle #2Taking out (Extraction)

4Object-affected harmful factors

If solid wall design is used for embedded system, then watertight integrity is achieved, but locking members cannot pass through

Engineering Contradiction:
ImproveWater ingress preventionVSAvoidLocking mechanism accessibility
Core Design Contradiction:
Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The patent introduces a locking system as an intermediary structure that interfaces with the solid wall. The locking system includes locking members that can be inserted through controlled access points and locked into position against the solid wall, maintaining the watertight integrity of the wall while providing accessible locking functionality through the intermediary locking mechanism

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

The invention concerns a support and attachment base (10) of an on-board system for supporting an on-board system on a support surface and for attaching it to a locking system equipped with locking members. This base comprises a planar attachment face (12), a support wall (14) parallel to the attachment face (12), connecting elements (16) perpendicular to the attachment face (12) securing the support wall (14) and the attachment face (12), removable assembly elements (18) provided on the attachment face (12), and, through the support wall (14), a locking opening (20) for the insertion of the locking members into an inner housing (22) defined by the attachment face (12), the support wall (14) and the connecting elements (16).
