Solution Overview

Problem

Existing home electrical network devices face issues with ergonomic wire connections, space occupancy, and mechanical stress on electrical modules due to retaining springs, leading to potential module offset and deformation.

Innovation Solution

A mounting interface with an arch or bridge configuration that guides and centers the electrical module during insertion, applying mechanical constraints offset from the electrical connection area, reducing stress on the module and allowing easier connection verification.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If retaining springs are used to fix the application module to the mounting plate, then the module can be easily installed and removed, but the wires generate forces that push the module out of the mounting box, causing offset or difficulty in insertion

Engineering Contradiction:
Improveease of installationVSAvoidmodule positioning stability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The invention separates the fixation function from the electrical connection function. The mounting plate with fixation claws handles mechanical retention, while the power module with recessed connection area handles electrical connections. This segmentation allows wires to be connected without generating forces on the module body, eliminating the pushing-out effect while maintaining easy installation via the fixation claws.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention extracts the electrical connection area from the main body of the power module by creating a recessed connection area. This allows the connection to be made in a dedicated zone that is offset from the module's center of gravity and fixation points, preventing wire-induced forces from affecting module positioning while keeping the module securely held by the fixation claws.

Inventive Principle:
Principle #2Taking out (Extraction)

2Device complexity

If claws are directly anchored by screw to the electrical module, then the mounting interface is simplified, but the claws generate high compression forces on the module that can deform it, especially damaging fragile electronic components

Engineering Contradiction:
Improvemounting interface complexityVSAvoidmechanical stress on module
Core Design Contradiction:
Device complexityVSObject-affected harmful factors

Solution Approach 1:

The invention extracts the connection area for the claws from the main body of the power module by providing a recessed connection area. This allows the claws to be anchored to the mounting plate in a position that is offset from the module's sensitive electronic components, reducing compression forces on fragile parts while maintaining a simplified mounting interface.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The invention prepares the mounting plate with pre-positioned connection areas and fixation claw mounting holes before the module is installed. This preliminary preparation allows the claws to be anchored in optimal positions that minimize stress on the module while simplifying the installation process, as the mounting plate is already configured to receive the module in the correct orientation and position.

Inventive Principle:
Principle #10Preliminary action

3Adaptability or versatility

If long wires are used to connect external network to the power module, then connection flexibility is improved, but the wires occupy too much space in the mounting box

Engineering Contradiction:
Improveconnection flexibilityVSAvoidmounting box space
Core Design Contradiction:
Adaptability or versatilityVSVolume of stationary object

Solution Approach 1:

The invention utilizes the third dimension (depth) by creating a recessed connection area in the power module. This allows wires to be routed through and connected in a recessed zone that is offset from the module's front face, enabling shorter wire lengths to be used while maintaining connection flexibility and significantly reducing the space occupied by wires in the mounting box.

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