Solution Overview

Problem

In vehicles equipped with Advanced Driver Assistance Systems (ADAS), the panels of commercial vehicle boxes can collide with the chassis, potentially damaging sensors, which are critical for safety and compliance, and costly to replace.

Innovation Solution

A containment system that limits the free stroke of the panel around a hinge to prevent contact with the chassis, using a buffer mechanism connected to a control lever and a bistable mechanism to maintain the buffer in a position that avoids contact with the chassis, ensuring the sensors are protected during loading and unloading.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the box is equipped with hinged panels for easy loading/unloading, then the ease of operation is improved, but the risk of panel collision with the chassis increases, potentially damaging ADAS sensors

Engineering Contradiction:
Improveease of loading and unloadingVSAvoidsensor protection
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The containment system is activated before the panel can collide with the chassis. The control lever is positioned to engage the buffer mechanism in advance, creating a protective barrier that prevents harmful contact between the moving panel and the ADAS sensors on the chassis

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The buffer acts as an intermediary element between the hinged panel and the chassis. When the panel moves during loading/unloading operations, the buffer intercepts the motion and provides containment, preventing direct contact with the ADAS sensors while still allowing operational movement

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If the box is designed to overturn for facilitating loading/unloading, then the ease of operation is improved, but the harmful factors increase due to potential panel collision with the chassis

Engineering Contradiction:
Improveease of loading and unloadingVSAvoidsensor damage risk
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The containment system applies preliminary anti-action by positioning the buffer to counteract the potential harmful motion of the panel before collision can occur. During box overturning operations, the buffer is pre-positioned to intercept and contain the panel, preventing it from striking the ADAS sensors on the chassis

Inventive Principle:
Principle #9Preliminary anti-action

3Reliability

If a containment system is added to protect ADAS sensors, then the reliability is improved, but the device complexity increases

Engineering Contradiction:
Improvesensor protectionVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The control lever serves multiple functions: it controls the buffer mechanism for sensor protection, and it can be integrated with existing box operation controls. This multi-functionality reduces the need for separate dedicated components, thereby limiting the increase in device complexity while maintaining reliable sensor protection

Inventive Principle:
Principle #6Universality (Multi-functionality)
