Solution Overview

Problem

Existing head-mounted electronic devices are cumbersome and do not fully cover the user's field of view, leading to discomfort and reduced recognition of objects within the user's peripheral vision.

Innovation Solution

The device features a housing with a camera module inclined at a specific angle and a semi-transparent lens positioned at a greater angle relative to the perpendicular, allowing the camera's field of view to cover the user's entire field of view and reducing the perceived weight by distributing the load on the user's body.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If the camera module is positioned to cover the user's entire field of view, then the field of view coverage is improved, but the device complexity increases

Engineering Contradiction:

Core Design Contradiction:
Area of stationary objectVSDevice complexity

Solution Approach 1:

The camera module is inclined at a first angle with respect to a line perpendicular to the front surface, and the semi-transparent lens is inclined at a second angle greater than the first angle. This angular arrangement in a different dimensional orientation allows the camera to capture a wider field of view without proportionally increasing device complexity, as the angular positioning optimizes the optical path efficiency.

2Weight of moving object

If the load is concentrated on a smaller area of the user's body, then the perceived weight is reduced, but the structural strength requirements increase

Engineering Contradiction:
Improveperceived weightVSAvoidstructural strength
Core Design Contradiction:
Weight of moving objectVSStrength

Solution Approach 1:

The asymmetric angular positioning of the camera module (first angle) and semi-transparent lens (second angle greater than the first angle) creates an optimized load distribution pattern. This asymmetric configuration concentrates the mechanical load on a smaller, more structurally efficient area of the device housing, reducing the perceived weight on the user's head while maintaining structural integrity through strategic load path design.

Inventive Principle:
Principle #4Asymmetry

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

This configuration reduces user discomfort by ensuring the camera module captures the entire field of view and allows for the recognition of all objects within the user's vision, while minimizing the weight felt by the user by concentrating the load on a smaller area.
