Adjustable Corner Guard with Flexible Retainer Wings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing corner guards are not adjustable to accommodate various corner configurations, leading to high production and installation costs due to the need for custom manufacturing, which is time-consuming and impractical for as-needed production.
Innovation Solution
A two-piece corner guard with retainer wings coupled by flexible adhesive or fastener, allowing adjustable angles between 67 and 158 degrees, and a cover for impact absorption, constructed from durable materials like aluminum and impact-resistant plastic, enabling a single size to fit multiple configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If corner guards are custom-made to accommodate different corner configurations, then adaptability to various corner angles is improved, but manufacturing cost and production time increase
Solution Approach 1:
The corner guard is designed with a universal structure that can accommodate multiple corner configurations. The retainer wing includes a channel that can receive different cover shapes (e.g., 90-degree, 45-degree, obtuse angle covers), allowing a single retainer wing design to serve multiple corner angle requirements. This multi-functionality eliminates the need for custom manufacturing for each corner configuration.
Solution Approach 2:
The corner guard is divided into separate components: a retainer wing and a cover. The retainer wing is a standardized component that provides the mounting structure, while the cover is the configurable element that comes in different shapes to match different corner angles. This segmentation allows the retainer wing to be mass-produced universally while only the covers need variation.
2Manufacturing precision
If corner guards are custom-made for specific corner angles, then precision fit for particular configurations is improved, but productivity and installation efficiency decrease
Solution Approach 1:
The channel design in the retainer wing is universal and can accommodate multiple cover types. The cover includes engagement features that work with the channel regardless of the specific corner angle, allowing installers to quickly select and install the appropriate cover without custom fabrication, thereby maintaining both precision fit and high installation efficiency.
Solution Approach 2:
The corner guard system allows for dynamic selection of cover types based on the specific corner configuration encountered during installation. Rather than requiring precise pre-manufacturing for each angle, the system enables on-site adaptation by selecting from a range of standard cover shapes, improving both productivity and installation flexibility.
3Adaptability or versatility
If multiple differently configured corner guards are stored to accommodate various customers, then adaptability to different facilities is improved, but inventory complexity and storage costs increase
Solution Approach 1:
By designing the retainer wing to universally accommodate multiple cover types through its channel design, the system reduces inventory requirements. Instead of storing separate retainer wings for each corner angle, facilities can store a single retainer wing design with multiple interchangeable covers, significantly simplifying inventory management and reducing storage complexity.
Solution Approach 2:
The invention merges the functionality of multiple corner guard designs into a single retainer wing platform. Rather than maintaining separate inventory lines for 90-degree, 45-degree, and obtuse angle guards, the universal retainer wing combines all these functions, allowing facilities to manage a simplified inventory while maintaining adaptability to various corner configurations.
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
This design reduces manufacturing costs and allows for a highly configurable corner guard that can be easily adapted to various corner angles, decreasing production and installation costs while providing effective protection against traffic impacts.
Implementation Method 1
The retainer wings are coupled to one another by way of a durable tape or other such adhesive or fastener
Implementation Method 2
A cover is configured to receive the retainers in channels defined along edges thereof to provide a relatively impact absorbent surface about the corner of the wall

AI summary
A wall guard for use around wall corners is disclosed in which the wall guard includes a pair of retainers are flexibly mounted to one another. The retainers are coupled to one another by way of an adhesive tape material that extends over the back sides of the retainers. A cover is secured to the pair of retainers for absorbing impacts from passing traffic to thereby protect the corner of the wall against wear and tear.
