Solution Overview

Problem

Existing electronic devices equipped with imaging units, such as projectors or cameras, have fixed imaging units that cannot be adjusted in orientation, making them inconvenient for specific use cases.

Innovation Solution

A rotatable imaging module design featuring a non-circular shaft member and bracket configuration allows the imaging unit to be adjusted vertically and horizontally, enabling users to change its orientation as needed by using a combination of shaft members and fixing members.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the imaging unit is fixed on the casing of the electronic device, then the structure is simple and stable, but the user cannot adjust the orientation of the imaging unit, making it inconvenient for specific purposes

Engineering Contradiction:

Improveadjustability of imaging unit orientationVSAvoidstructure complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The imaging unit is transformed from a fixed state to a rotatable state by introducing a rotating mechanism. The imaging unit can rotate around a first shaft member along a first axis, and the shaft member itself can rotate around a second shaft member along a second axis, enabling dynamic orientation adjustment while maintaining structural integrity

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The mounting structure is divided into multiple independent components: the imaging unit, the first bracket with the first shaft member, and the second bracket with the second shaft member. This segmentation allows each component to perform its specific function independently, facilitating rotation and orientation adjustment without compromising the overall structure

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If the imaging unit is made rotatable to enable orientation adjustment, then user convenience is improved, but the structure becomes more complex

Engineering Contradiction:

Improveorientation adjustment capabilityVSAvoidmechanism complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The bracket structure serves multiple functions: it provides mechanical support for the imaging unit, enables rotation around the first shaft member, allows the shaft member to rotate around the second shaft member, and includes fixing members to secure the imaging unit at desired orientations. This multi-functionality reduces the need for additional separate components, thereby limiting the increase in structural complexity

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

An imaging module includes an imaging unit, a first bracket, a first shaft member and a first fixing member. The imaging unit includes a first circular hole. The first bracket includes a first non-circular hole. The first shaft member includes a first non-circular shaft portion. The first non-circular shaft portion is disposed in the first non-circular hole and the first circular hole, such that the first shaft member is disposed on the first bracket and the imaging unit is rotatably disposed on the first shaft member. The first fixing member is fixed on an end of the first shaft member.
