Snap-On Bracket Clamp Assembly for Torque-Resistant Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mounting clamps, particularly those with plastic components, face issues such as damage from torque, bolt loosening, and the need to open the clamp to access fasteners, which complicates securement and connection of objects to support structures.
Innovation Solution
The introduction of snap-on bracket clamp assemblies, which consist of a metal bracket and a polymeric mounting clamp. The mounting clamp is designed to snap onto the metal bracket, allowing for proper torque application to the support structure without damaging the clamp, and enabling securement and connection of objects without needing to open the clamp.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a plastic mounting clamp is used to secure objects to a support structure, then the clamp can be easily installed and provides adequate holding force, but the plastic boss surrounding the orifice can be plastically deformed or cracked when torque is applied
Solution Approach 1:
The mounting clamp is divided into two functional segments: a plastic clamp body for easy installation and holding, and a separate metal reinforcement element (insert or boss) specifically designed to withstand torque. This segmentation allows each component to be optimized for its specific function without compromising the other.
Solution Approach 2:
The mounting clamp combines two different materials with complementary properties: plastic (polymer) providing ease of installation, molding flexibility, and corrosion resistance, and metal (such as steel or aluminum) providing high strength and torque resistance. The composite structure leverages the advantages of both materials to resolve the contradiction between ease of installation and torque resistance.
2Strength
If a metal compression limiter is integrated into the orifice to prevent plastic deformation, then torque resistance is improved, but the solution is not suitable for all applications and increases complexity
Solution Approach 1:
The metal reinforcement element serves multiple functions simultaneously: it reinforces the plastic boss against torque, provides a bearing surface for the bolt head, and can be designed with various geometries to accommodate different application requirements. This multi-functionality reduces the need for separate components and simplifies the overall structure.
Solution Approach 2:
The metal reinforcement is strategically placed only in the critical areas where torque is applied (such as the boss region and orifice area), while the rest of the clamp body remains plastic. This localized reinforcement minimizes the amount of metal required and reduces overall complexity while still providing adequate torque resistance.
3Strength
If the clamp structure is modified to accommodate fasteners, then proper torque application is enabled, but the clamp must be opened to access fasteners which complicates the securement process
Solution Approach 1:
The fasteners (bolts, screws, or rivets) and their access paths are designed and positioned during the clamp manufacturing process. The clamp body is molded or formed with integrated fastener receptacles, counterbores, or clearance holes that provide direct access to the fastener heads without requiring the clamp to be opened or disassembled. This preliminary arrangement of fastener access paths enables torque application while maintaining clamp integrity.
4Object-affected harmful factors
If a bolt mount ratchet clamp is used for low- to medium-torque applications, then the plastic boss can prevent damage, but the clamp is limited in its ability to handle high-torque applications
Solution Approach 1:
The clamp design incorporates adjustable parameters such as the size, shape, and material properties of the metal reinforcement element. By varying these parameters, the same basic clamp design can be adapted for different torque requirements, from low- to high-torque applications, thereby expanding the application range while maintaining protection from torque damage.
