Dunnage Securement Member Structure for Stable Timber Restraint
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The shifting and movement of timbers used as dunnage during transportation pose safety hazards due to the risk of them sticking out past the trailer sides, falling onto the road, and causing damage or harm to vehicles and motorists, as they are not effectively secured.
Innovation Solution
A dunnage securement member with a rectangular body, slots for bolts, a rounded end for securing straps, and pins to retain the strap, designed to be affixed to timbers, allowing for adjustable length and securement to prevent movement and moisture evaporation to prevent rotting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If timbers are placed across the flat bed surface to support heavy loads, then the load can be elevated and distributed, but the timbers shift and move around during transport creating safety hazards
Solution Approach 1:
The securement member is divided into distinct functional segments: a body portion that interfaces with the timber, a rounded end for strap attachment, and multiple slots for bolt securing. This segmentation allows each component to perform its specific function effectively while working together to prevent timber movement.
Solution Approach 2:
The securement member is pre-configured with slots and rounded ends before use. The slots are pre-positioned to accommodate bolts at optimal locations, and the rounded ends are prepared to receive straps, enabling quick and effective securement without requiring complex on-site assembly.
2Reliability
If multiple securement features are added to prevent timber movement, then safety is improved, but the device complexity increases
Solution Approach 1:
Multiple securement functions are merged into a single integrated member: the body provides structural support, slots enable bolt attachment, and rounded ends facilitate strap securing. This consolidation achieves reliable multi-point securement without requiring separate devices for each function.
Solution Approach 2:
The securement member is designed to perform multiple functions simultaneously: it anchors to the timber via slots, provides strap attachment points via rounded ends, and maintains structural integrity under load. This multi-functionality reduces the number of separate components needed.

AI summary
A dunnage securement member is adapted to placed on the ends of timber that is used as dunnage for trucking. The dunnage securement member is adapted to be secured to the timber, either permanently or removably. A strap may then be used to secure dunnage on the beds of a truck.
