Shooting Support Foot Hinge Structure With Integrated Retaining Walls

Solution Overview

Problem

Existing shooting auxiliary supports have complex connection structures that lead to high installation costs due to the need for a limiting part and a separate mold, making the installation process time-consuming and laborious.

Innovation Solution

A support structure with a simplified rotating connection between the supporting foot and rib, utilizing a first rotating shaft sandwiched between retaining walls to facilitate easy installation without a limiting part, and an accommodating groove for smooth rotation and storage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a limiting part is used to connect supporting ribs to supporting feet, then the rotating connection is achieved, but the installation process becomes time-consuming and laborious, and production costs increase due to separate mold requirements

Engineering Contradiction:

Improverotating connection reliabilityVSAvoidconnection structure complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts and removes the separate limiting part from the connection structure. Instead of using a distinct limiting component that requires separate installation and molding, the limiting function is integrated directly into the supporting foot structure through retaining walls, thereby simplifying the overall connection structure while maintaining reliable rotating connection

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent merges the limiting function with the supporting foot structure by incorporating retaining walls that are integrally formed with the supporting foot. This integration eliminates the need for a separate limiting part and its associated mold, reducing both structural complexity and production costs while ensuring reliable rotation limitation

Inventive Principle:

Principle #5Merging (Combining)

2Reliability

If a limiting part is used to connect supporting ribs to supporting feet, then the rotating connection is achieved, but production costs increase due to separate mold requirements

Engineering Contradiction:

Improverotating connection reliabilityVSAvoidmanufacturing cost

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The patent extracts and removes the separate limiting part from the connection structure. Instead of using a distinct limiting component that requires separate installation and molding, the limiting function is integrated directly into the supporting foot structure through retaining walls, thereby simplifying the overall connection structure while maintaining reliable rotating connection

This integration eliminates the need for a separate limiting part and its associated mold, reducing both structural complexity and production costs while ensuring reliable rotating connection

Inventive Principle:

Principle #5Merging (Combining)

3Reliability

If retaining walls are used to sandwich the rotating shaft, then the rotating connection is stable, but the installation space requirement increases

Engineering Contradiction:

Improverotating connection stabilityVSAvoidinstallation space

Core Design Contradiction:

ReliabilityVSVolume of moving object

Solution Approach 1:

The patent utilizes the width direction of the supporting foot to arrange the first and second retaining walls, creating a compact sandwich structure for the rotating shaft. This dimensional arrangement ensures stable rotation limitation while maintaining a compact installation space that fits within the supporting foot structure

Inventive Principle:

Principle #17Another dimension (Dimensionality change)
