Shared-Sheath Wiring Harness for Compact VR Headsets

Solution Overview

Problem

The design of head-mounted devices, particularly all-in-one VR machines, faces challenges due to the need for thick battery lines caused by high power consumption and large battery capacity, which occupy significant structural space.

Innovation Solution

A wiring harness with a shared outer sheath for signal lines, grounding wires, and power cables, allowing for a more compact arrangement that reduces wiring space and overall dimensions, while improving current flow capability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Power

If thick battery lines are used to handle high power consumption and large battery capacity, then current flow capability is improved, but wiring space increases and overall dimensions increase

Engineering Contradiction:

Improvecurrent flow capabilityVSAvoidwiring space

Core Design Contradiction:

PowerVSVolume of moving object

Solution Approach 1:

The patent combines multiple cables (power cable, signal line, grounding wire) into a single integrated wiring harness with a shared outer sheath. This merging allows the cables to be bundled together efficiently, reducing the total wiring space required while maintaining the current flow capability of individual thick power conductors. The power cable and signal line share the same outer sheath, creating a compact assembly that fits within limited structural space.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent employs a nested structure where the power cable, signal line, and grounding wire are all disposed within a common outer sheath. This nesting arrangement allows multiple cable components to occupy overlapping spatial volumes, significantly reducing the overall wiring space and dimensions compared to having separate cable assemblies. The inner cables are nested within the protective outer sheath, creating a space-efficient configuration.

Inventive Principle:

Principle #7Nested doll (Nesting)

3Adaptability or versatility

If multiple separate cables are used for power, signal, and grounding, then functional separation is improved, but wiring space increases

Engineering Contradiction:

Improvefunctional separationVSAvoidwiring space

Core Design Contradiction:

Adaptability or versatilityVSVolume of moving object

Solution Approach 1:

The patent combines multiple cables (power cable, signal line, grounding wire) into a single integrated wiring harness with a shared outer sheath. This merging allows the cables to be bundled together efficiently, reducing the total wiring space required while maintaining the current flow capability of individual thick power conductors. The power cable and signal line share the same outer sheath, creating a compact assembly that fits within limited structural space.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

While merging the cables into a common outer sheath, the patent maintains functional separation by keeping the power cable, signal line, and grounding wire as distinct internal components with different cross-sectional areas and arrangements. The power cable contains thick conductors for high current, the signal line has thinner conductors for data transmission, and the grounding wire provides safety earth connection. This segmentation within integration allows both functional differentiation and space efficiency.
