Shape-Memory Bumper for Compact Shipping and Damage Recovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high cost and inefficiency of shipping vehicle bumpers, particularly due to their rigid materials like fiberglass and ABS plastic, which are prone to damage and breakage during transportation, and the limitations of international shipping methods.
Innovation Solution
A foldable bumper constructed from a composition of isocyanate, resin, and a memory agent, allowing it to be compacted for shipping and returning to its original shape when heated, enabling cost-effective and timely delivery, including direct international shipments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If bumpers are made from rigid materials like fiberglass or ABS plastic, then strength and durability are improved, but shipping cost and damage risk increase
Solution Approach 1:
The patent changes the physical state and mechanical properties of the bumper material by incorporating a memory agent that allows the material to transition between rigid and flexible states. The bumper material is formulated with specific proportions of resin (30-70 parts), isocyanate (10-40 parts), and memory agent (1-20 parts) to achieve optimal flexibility for folding while maintaining strength for damage recovery
Solution Approach 2:
The patent creates a composite material system combining resin, isocyanate, and memory agent to achieve properties that neither individual component possesses alone. This composite formulation enables the bumper to be both foldable for shipping and self-repairing for durability, resolving the contradiction between strength and shipping reliability
2Stability of the object's composition
If bumpers are made from rigid materials, then structural integrity is improved, but ease of shipping and cost-effectiveness worsen
Solution Approach 1:
The patent introduces dynamic properties to the bumper material through the memory agent, allowing the bumper to change its physical state from rigid to flexible on demand. This enables the bumper to be folded for shipping and then return to its original rigid state for installation, making shipping as easy as shipping flexible materials while maintaining structural integrity
Solution Approach 2:
The patent modifies the material parameters by incorporating a memory agent in specific concentrations (1-20 parts per 100 parts resin) that enables reversible changes in the material's physical properties, allowing easy folding for shipping while maintaining structural integrity when needed
3Ease of operation
If traditional freight shipping is used for bumpers, then delivery capability is achieved, but shipping cost and delivery time increase
Solution Approach 1:
The patent changes the physical parameters of the bumper to enable standard ground shipping instead of specialized freight shipping. By making the bumper foldable through the memory agent formulation, the product can be packaged in regular boxes and shipped via standard carriers, reducing delivery time from weeks to days and eliminating the need for expensive freight services
4Reliability
If rigid materials are used for bumpers, then durability during use is improved, but susceptibility to shipping damage increases
Solution Approach 1:
The patent changes the material parameters by incorporating a memory agent that enables the bumper to flex during shipping without permanent deformation, then return to its original shape afterward. This eliminates shipping damage while maintaining durability during use, as the material can withstand both flexible handling and rigid service conditions
Solution Approach 2:
The patent implements self-service through the memory agent's automatic shape recovery function. When the bumper is dented or damaged during shipping or use, the memory agent automatically triggers shape recovery when exposed to heat (such as sunlight or warm water), eliminating the need for manual repair and maintaining bumper durability without requiring external intervention
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
The foldable bumper reduces shipping costs and damage risks by allowing for ground transportation and direct user delivery, while the memory agent ensures the bumper can be easily restored to its original shape after dents or damage.
Implementation Method 1
a composition of an isocyanate, resin, and a memory agent blend... the bumper can return to its original shape if dented or damaged

AI summary
A method of manufacturing, packing and shipping a vehicle bumper having the steps of dispensing into a bumper mold a shape-memory composition to form an original shape of an integral shape-memory vehicle bumper having a middle portion and a first end and a second end both extending from opposite ends of the middle portion, the shape-memory vehicle bumper having the original shape fitting in a first shipping box; applying force to the shape-memory vehicle bumper such that to cause a conversion of the original shape into a deformed shape of the shape-memory vehicle bumper, the deformed shape fitting into a second shipping box that is a fraction by volume of the first shipping box; placing the shape-memory vehicle bumper having the deformed shape into the second shipping box; and sealing and shipping the second shipping box.
