Solution Overview

Problem

The existing fixing brackets for sprinkler reducers are cumbersome to assemble, require separate tools, and have low clamping force due to direct bolt contact with the rectangular bar, leading to potential damage and instability during installation and removal.

Innovation Solution

A fixing bracket with a body portion and coupling portion formed by cutting and bending a steel plate, featuring a hinge mechanism, cover member, pivoting member, and fastening member that allows for one-touch attachment and detachment without bolts, enhancing clamping force and stability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If bolts are used to fix the reducer to the rectangular bar, then the reducer can be fixed, but the assembling structure becomes complicated and cumbersome

Engineering Contradiction:
Improvefixing stabilityVSAvoidassembling structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The invention extracts and eliminates the bolts from the fixing mechanism. Instead of using separate bolts to fasten the reducer to the rectangular bar, the design integrates the fixing function directly into the bracket structure through the hook-shaped fastening member that engages with the rectangular bar's groove, simplifying the assembling structure while maintaining reliability

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The invention merges the fixing function with the bracket structure itself. The hook-shaped fastening member is integrated into the bracket body, combining the support and fixing functions into a single unified structure, eliminating the need for separate fastening components

Inventive Principle:
Principle #5Merging (Combining)

2Reliability

If bolts are used to fix the reducer, then the reducer can be secured, but separate tools are required for tightening

Engineering Contradiction:
Improvefixing stabilityVSAvoidinstallation convenience
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The invention removes the bolts and required tightening tools from the system. The hook-shaped fastening member provides a tool-free fixing mechanism that can be installed and adjusted by hand, greatly improving ease of operation while maintaining securing reliability

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The hook-shaped fastening member is designed to be manually operable without external tools. The user can directly engage and disengage the hook with the rectangular bar's groove using hand force, making the system self-sufficient and eliminating dependency on separate tightening tools

Inventive Principle:
Principle #25Self-service

3Ease of manufacture

If bolts directly contact the rectangular bar for fixing, then the reducer can be attached, but the clamping force is lowered and the rectangular bar may be damaged

Engineering Contradiction:
Improveattachment simplicityVSAvoidclamping force
Core Design Contradiction:
Ease of manufactureVSStrength

Solution Approach 1:

The invention introduces a groove structure in the rectangular bar as an intermediary element. The hook-shaped fastening member engages with this groove, distributing the clamping force along the groove's surface rather than concentrating it at a single bolt contact point, thereby increasing overall clamping force and preventing damage to the rectangular bar

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The invention transitions from point-contact fixing (bolts) to line-contact fixing (groove engagement). The hook-shaped fastening member engages with the rectangular bar along the groove's length, distributing the fixing force over a larger area and increasing clamping effectiveness while reducing stress concentration

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

4Reliability

If bolts are used for fixing, then the reducer can be secured, but detachment and attachment become inconvenient when replacing the reducer

Engineering Contradiction:
Improvefixing stabilityVSAvoidreplacement time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The invention removes bolts and the associated multi-step tightening/loosening process. The hook-shaped fastening member allows for quick one-handed engagement and disengagement by simply moving the hook along the rectangular bar's groove, dramatically reducing replacement time while maintaining fixing stability

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The hook-shaped fastening member is designed with movable flexibility, allowing it to be easily positioned and engaged at different locations along the rectangular bar's groove. This dynamic capability enables quick adjustment and rapid replacement without the rigid, time-consuming bolt tightening process

Inventive Principle:
Principle #15Dynamics
