Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for protecting roadside mailboxes from impact damage by snowplows are either aesthetically deficient, short-lived, or lack reinforcement against impact forces, with current devices failing to effectively deflect snow and withstand impact.
Innovation Solution
A mailbox protection device featuring an angular deflection surface with planar panels and a receiving channel that integrates with a standard steel tee fence post, providing structural support and orientation to deflect snow and absorb impact forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If an angular shield is used to deflect snow, then snow deflection is improved, but impact resistance deteriorates because the device is unreinforced against impact
Solution Approach 1:
The shield is divided into multiple planar members (first planar member, second planar member, third planar member) that are contigously arranged to form an angular structure. This segmentation allows each panel to be optimized for snow deflection while the collective structure provides impact resistance through the reinforcing members that connect them.
Solution Approach 2:
The device combines planar shield members with reinforcing members to create a composite structure. The planar members provide the angular surface for snow deflection, while the reinforcing members (which may be metallic or other high-strength materials) provide the necessary impact resistance without compromising the aerodynamic deflection function.
2Object-affected harmful factors
If a make-shift shield made from plywood and wooden posts is used, then snow deflection is improved, but durability deteriorates because the materials warp and rot
Solution Approach 1:
The invention changes the material parameters from organic materials (plywood, wood) that are susceptible to warping and rotting to inorganic, weather-resistant materials. The planar members can be made from metal, plastic, or treated composite materials that maintain their structural integrity and aesthetic appearance over extended periods of outdoor exposure.
Solution Approach 2:
The device uses composite or composite-like structures where the planar members are supported by reinforcing members. This composite approach allows the use of aesthetically pleasing, weather-resistant materials for the visible surfaces while incorporating structurally robust materials for support, achieving both durability and appearance.
3Strength
If a sturdy structure like a brick encasement is built around the mailbox, then impact resistance is improved, but aesthetic quality deteriorates
Solution Approach 1:
The reinforcing members are strategically positioned to provide impact resistance only where needed - at the corners and edges of the angular shield structure that are most susceptible to impact forces. The visible planar surfaces maintain clean, simple lines for aesthetic appeal, while the reinforcement is localized to functional areas, minimizing visual impact.
Solution Approach 2:
The angular shield with its reinforcing members serves as an intermediary protective structure that stands between the mailbox and the environmental hazards. It provides the necessary structural strength and impact resistance while maintaining a sleek, modern aesthetic that can complement rather than detract from the mailbox's appearance, unlike bulky brick encasements.
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 device effectively deflects snow and supports against impact forces, offering a robust and aesthetically acceptable solution that is durable and cost-effective, with the ability to be easily installed and oriented for optimal protection.
Implementation Method 1
design the mailbox itself so that it is more aerodynamic, thereby allowing impacting snow to be deflected away
Implementation Method 2
the top opening and the bottom opening are keyed to receive the standard steel tee fence post in a preferred orientation wherein the base of the tee is directed toward the linear vertex
Implementation Method 3
build a sturdy structure around the mailbox, like a brick encasement

AI summary
A mailbox protection device is provided. The device may include an angular deflection surface. The angular deflection surface may include a first planar deflection panel and a second planar deflection panel contiguous along a linear vertex. The linear vertex may be directed toward, for example, oncoming traffic to deflect impacting snow away from a mailbox. The impacting snow may come from passing snowplows, for instance. The device may also include a receiving channel. The receiving channel can be defined in the linear vertex extending through the device from an opening at a top end of the linear vertex to an opening at a bottom end of the linear vertex. The receiving channel may receivably cooperate with a known fence post to anchor the device in the ground.
