Solution Overview

Problem

Existing hemispherical cameras have complex structures and cumbersome methods for adjusting the lens component along the P-direction during setup.

Innovation Solution

A P-direction adjustable structure for hemispherical cameras, comprising an upper cover component, a pin, a cylindrical base, and a wire hidden case, allows for simple and efficient adjustment by locking and releasing the rotational freedom of the base relative to the wire hidden case using a pin mechanism.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a complex structure is used for hemispherical cameras, then the lens component can be adjusted in three directions, but the adjustment method becomes cumbersome and setup efficiency decreases

Engineering Contradiction:
Improvelens component adjustmentVSAvoidstructure complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The camera structure is divided into separate functional modules: the base for supporting the lens component, the upper cover component for sealing, and the wire hidden case for wire management. This segmentation allows each component to be optimized independently and simplifies the adjustment mechanism.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The base is designed with rotational freedom relative to the wire hidden case, allowing dynamic adjustment of the lens component in the P-direction. The pin mechanism provides controllable locking and releasing, enabling easy adjustment while maintaining structural integrity during operation.

Inventive Principle:
Principle #15Dynamics

2Temperature

If the base is directly exposed for heat dissipation, then heat dissipation efficiency improves, but the sealed and waterproof chamber structure becomes compromised

Engineering Contradiction:
Improveheat dissipation efficiencyVSAvoidsealed and waterproof chamber
Core Design Contradiction:
TemperatureVSReliability

Solution Approach 1:

The camera housing is segmented into the base, upper cover component, and wire hidden case. This segmentation allows the base to be exposed for heat dissipation while the upper cover component maintains the sealed and waterproof chamber structure, resolving the contradiction between heat dissipation and sealing.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different parts of the camera structure have different properties: the base is designed for heat dissipation with direct exposure, while the upper cover component is designed for sealing and waterproofing. This local differentiation of structural properties allows both heat dissipation and sealing requirements to be satisfied simultaneously.

Inventive Principle:
Principle #3Local quality

AI summary

The present application discloses a P-direction adjustable structure and a hemispherical camera. Wherein, the P-direction adjustable structure is applied to a hemispherical camera and includes: an upper cover component, a pin, a base, and a wire hidden case; the base is rotatably connected to the wire hidden case ; the upper cover component is installed on the base; the upper cover component is provided with a raised part, which can drive the pin to switch between a releasing position and a locking position; wherein, when the pin is switched to the locking position, the rotational degree of freedom of the base and the wire hidden case is locked; when the pin is switched to the releasing position, the locking is released. The P-direction adjustable structure of the present application has a simple structure and is easy to operate. The tightening operation in the P-direction is very simple, as long as the upper cover is normally shut and fastened, without a redundant operation.
