Solution Overview

Problem

Existing electricity connection boxes are too large and require a reduction in size without compromising their functionality.

Innovation Solution

The design incorporates a housing with multiple insertion ports and connection portion groups, where each group is positioned relative to its corresponding insertion port to minimize wire overlap and optimize space usage, allowing for a compact configuration of electronic components and electric wire groups.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple connection portion groups are arranged inside the housing, then the functionality for accommodating multiple electric wire groups is improved, but the size of the connection box increases

Engineering Contradiction:

ImprovefunctionalityVSAvoidsize

Core Design Contradiction:

Adaptability or versatilityVSVolume of moving object

Solution Approach 1:

The patent transitions from planar arrangement to three-dimensional spatial arrangement by positioning connection portion groups at different depths along the insertion direction. The first connection portion group is arranged closer to the first insertion port while the second connection portion group is arranged closer to the second insertion port, utilizing the depth dimension to accommodate multiple connection groups without increasing the overall footprint of the housing.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The housing is segmented into distinct regions with separate connection portion groups positioned at different locations. Each connection portion group is spatially separated and assigned to specific insertion ports, allowing independent access and connection management while optimizing the use of internal space.

Inventive Principle:

Principle #1Segmentation

2Object-generated harmful factors

If connection portion groups are positioned closer to their corresponding insertion ports, then wire overlap is prevented, but the internal space arrangement becomes more complex

Engineering Contradiction:

Improvewire overlapVSAvoidinternal space arrangement

Core Design Contradiction:

Object-generated harmful factorsVSDevice complexity

Solution Approach 1:

Different regions of the housing are assigned different functional qualities - the first connection portion group is positioned in the region closer to the first insertion port while the second connection portion group is positioned in the region closer to the second insertion port. This local optimization prevents wire overlap by ensuring that wires inserted through different ports connect to nearby connection portions without crossing paths.

Inventive Principle:

Principle #3Local quality

AI summary

An electricity connection box includes a housing which includes a first insertion port and a second insertion port, a first connection portion group made of connection portions which are provided inside the housing and to which electric wires of a first electric wire group are connected, and a second connection portion group made of connection portions which are provided inside the housing and to which electric wires of a second electric wire group are connected. The first electric wire group is inserted through the first insertion port, and the second electric wire group is inserted through the second insertion port. The first connection portion group is closer to the first insertion port than the second connection portion group. The second connection portion group is closer to the second insertion port than the first connection portion group.
