Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing anchors are difficult to install, unstable, and fail to adequately support heavy loads, especially in drywall, often leading to damage over time.
Innovation Solution
A support device with an elongate body featuring a support head and shank portion, designed for easy installation with a torque tool-compatible recess and a screw-threaded shank for secure anchoring in various materials, including drywall, with a shoulder flange for stability and a design that accommodates heavy weights.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional anchors are used, then installation is simple, but they are unstable and cannot adequately support heavy loads
Solution Approach 1:
The support device is divided into distinct functional segments: a head portion for engagement, a neck portion for connection, and a shank portion for anchoring. This segmentation allows each part to be optimized for its specific function while maintaining overall structural integrity and ease of installation.
Solution Approach 2:
The support device incorporates a pre-formed head portion with engagement features and a shank portion with anchoring features already integrated during manufacturing. This preliminary preparation eliminates the need for complex field assembly or specialized installation tools, making installation simple while ensuring stable load-bearing performance.
2Reliability
If traditional anchors are used, then they are easy to install, but they loosen over time causing damage
Solution Approach 1:
The head portion, neck portion, and shank portion are merged into a single integrated support device structure. This unity ensures consistent performance over time as all components work together without relative movement or loosening, eliminating the reliability issues of traditional multi-component anchors while maintaining reasonable structural complexity.
Solution Approach 2:
Instead of relying on friction or expansion mechanisms that may loosen over time, the invention inverts the approach by using a mechanical interlocking system where the head portion engages the article and the shank portion anchors to the structure, creating a stable connection that resists loosening through its geometric design rather than friction alone.
3Strength
If anchors are designed for heavy load support, then they provide adequate strength, but they require specialized tools and skills for installation
Solution Approach 1:
The support device is designed to be self-installing without requiring specialized tools or skills. The head portion with its engagement features and the shank portion with anchoring features work together in a way that allows straightforward installation by any user, while still providing the strength to support heavy loads.
4Strength
If anchors are designed for stability, then they can support heavy loads, but they may damage the support structure
Solution Approach 1:
The shank portion is designed with specific anchoring features optimized for the local conditions of the support structure. This localized optimization allows the anchor to achieve strong holding power while minimizing damage to the surrounding structure, as the anchoring mechanism is tailored to interact appropriately with the specific support material.

AI summary
A device for supporting an article on a structure. The support device includes an elongate body with a head at one end, a neck, a shoulder flange, and an elongate threaded shank with threads extending therefrom. The head and/or neck may be arranged to engage the article, and the shoulder flange has a surface for engaging a corresponding surface of the structure. The elongate shank portion anchors the support device at a target site on the structure and tapers from a greatest diameter proximate to the shoulder flange to a pointed end. The initial taper is at a lesser angle to the longitudinal axis of the elongate body to a point where the angle increases, before which the threads may terminate.
