Solution Overview

Problem

Current mounting and fixing apparatuses for analog-to-digital electrical equipment on standardized rails are cumbersome and time-consuming, limiting interchangeability and compatibility, making it difficult to mount, dismount, and replace equipment without disassembling the entire system.

Innovation Solution

A mounting and fixing apparatus featuring a hook structure with a stop element and guide-rail system that allows the electrical equipment-insulated pedestal to be easily clipped and unclipped from the mounting rail, enabling transverse movement and adjustment of the equipment's position, facilitated by an elastic link stopper and tongue-shaped plate for secure locking and unlocking.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the opening dimension on the electrical equipment-insulated pedestal is made equal to the mounting rail width for firm attachment, then the reliability of mounting is improved, but the ease of operation for transverse movement and replacement deteriorates

Engineering Contradiction:
Improvemounting reliabilityVSAvoidease of transverse movement
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The stop element is designed to be movable along the mounting rail within guide slots, transforming the static opening dimension into a dynamic adjustable parameter. This allows the opening to adapt between two states: constrained for firm attachment and movable for transverse movement, resolving the contradiction between mounting reliability and ease of operation.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The position of the stop element changes the effective opening dimension dynamically. When the stop element is repositioned, it alters the distance between the fixing protrusion and fixing recess, enabling the system to switch between firm attachment mode and transverse movement mode, thus resolving the contradiction.

Inventive Principle:
Principle #35Parameter changes

2Manufacturing precision

If the opening dimension is fixed and equal to the mounting rail width, then the manufacturing precision is improved, but the adaptability for interchangeability and compatibility deteriorates

Engineering Contradiction:
Improveopening dimension precisionVSAvoidinterchangeability and compatibility
Core Design Contradiction:
Manufacturing precisionVSAdaptability or versatility

Solution Approach 1:

The stop element's movability along the mounting rail creates a dynamic adjustment mechanism that preserves precise manufacturing of individual components while enabling adaptability through positional variation. The guide slots ensure precise movement paths, maintaining manufacturing precision while achieving interchangeability.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The adjustable opening dimension allows the same electrical equipment-insulated pedestal to work with different mounting rail configurations and positions, enhancing universality and compatibility without requiring different precision specifications for each variant.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Strength

If all bolts fixing the omnibus bar must be unscrewed to replace electrical equipment, then the strength of the fixed connection is improved, but the productivity for replacement operations deteriorates

Engineering Contradiction:
Improveconnection strengthVSAvoidreplacement efficiency
Core Design Contradiction:
StrengthVSProductivity

Solution Approach 1:

The mounting system is segmented into independently movable components: the stop element can move independently along the mounting rail, and the electrical equipment can be removed independently without affecting other equipment on the omnibus bar. This segmentation enables selective replacement without dismantling the entire system, improving productivity while maintaining connection strength.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The dynamic positioning capability of the stop element allows electrical equipment to be quickly released and repositioned along the mounting rail, dramatically improving replacement efficiency compared to the static bolt-fixed system that requires complete disassembly.

Inventive Principle:
Principle #15Dynamics
