Innovation Solution

A light-direction adjustment device with a curved adjustment unit that fits within a receiving chamber, featuring synchronized first and second driving members, heat dissipating elements, and sealing members to maintain stability and prevent space occupation during adjustments, while ensuring efficient heat dissipation and protection from environmental pollutants.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the lamp body performs a rotating movement relative to the supporting component to change light direction, then the light emission direction can be adjusted, but the device occupies additional and constantly changing space

Engineering Contradiction:
Improvelight direction adjustmentVSAvoidspace occupation
Core Design Contradiction:
Adaptability or versatilityVSVolume of moving object

Solution Approach 1:

The adjustment unit is nested within the lamp body, with the curved adjustment unit fitting inside a receiving chamber formed by the lamp body and housing. This nesting arrangement allows the adjustment mechanism to be contained within the existing device volume, preventing additional space occupation during angle adjustments while maintaining full light direction adjustability.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The adjustment unit employs a curved structure that coordinates with the curved first and second driving surfaces. This curved geometry enables compact packaging of the adjustment mechanism within the receiving chamber, allowing the lamp body to rotate through various angles while maintaining a compact overall form factor that does not expand the device envelope.

Inventive Principle:
Principle #14Spheroidality (Curvature)

2Volume of moving object

If the adjustment unit is designed with curved structures to fit within the receiving chamber, then space occupation is minimized, but the manufacturing complexity increases

Engineering Contradiction:
Improvespace occupationVSAvoidmanufacturing complexity
Core Design Contradiction:
Volume of moving objectVSEase of manufacture

Solution Approach 1:

The adjustment unit and driving surfaces utilize curved geometries that are consistent with conventional molding and machining techniques. The curved adjustment unit, first curved driving surface on the housing, and second curved driving surface on the lamp body can be manufactured using standard industrial processes, balancing the compact space-saving design with manufacturing feasibility.

Inventive Principle:
Principle #14Spheroidality (Curvature)

3Reliability

If the device is designed for outdoor or polluted environments, then durability is improved, but sealing requirements and device complexity increase

Engineering Contradiction:
Improveenvironmental stabilityVSAvoidsealing structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The device incorporates sealing members that form protective barriers between the adjustment unit and the external environment. These sealing structures, integrated into the housing and lamp body assembly, prevent dust and moisture ingress without requiring complex separate sealing components, maintaining reliability while controlling overall device complexity.

Inventive Principle:
Principle #30Flexible shells and thin films
