Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing number of product models and specifications in outdoor lamps leads to inventory pressure and waste due to the need for multiple lenses with different light-emitting angles, which increases costs and complexity.
Innovation Solution
A lamp design with a translatable lens system that allows adjustment of light-emitting angles using adjustment knobs, symmetrical racks, and sealing grooves, ensuring waterproofing and convenient operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple lenses with different light-emitting angles are incorporated into a single product, then the adaptability of the product is improved, but the device complexity and inventory management difficulty increase
Solution Approach 1:
The patent applies the dynamics principle by making the lens translatable along the optical axis. Instead of having multiple fixed lenses for different angles, a single lens can be moved to different positions to achieve different light-emitting angles. The lens assembly includes a lens holder that can translate along the optical axis, with the lens positioned at different locations to control the beam angle dynamically.
Solution Approach 2:
The patent implements universality by designing a single lens assembly that can perform multiple functions. The same lens structure serves different light-emitting angle requirements by translating to different positions along the optical axis. This eliminates the need for multiple separate lenses, as one universal lens assembly can replace several specialized lenses.
2Adaptability or versatility
If multiple lenses with different light-emitting angles are incorporated into a single product, then the adaptability of the product is improved, but the loss of substance increases due to discarding remaining lenses
Solution Approach 1:
The patent applies discarding and recovering by eliminating the need to discard lenses. Instead of discarding unused lenses when changing light-emitting angles, the system recovers and utilizes the same lens by translating it to different positions. The lens is not discarded but rather repositioned to serve different functional requirements.
Solution Approach 2:
The single translatable lens assembly serves multiple angle requirements, making it a universal component that replaces multiple specialized lenses. This universality prevents substance loss by ensuring the same lens material is reused for different applications rather than being discarded.
3Ease of operation
If a translatable lens system with adjustment knobs is implemented, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The patent applies self-service by enabling the user to directly adjust the lens position through manually operable adjustment knobs. The adjustment mechanism allows end-users to translate the lens along the optical axis without requiring specialized tools or complex procedures. The system serves itself by providing intuitive manual control for angle adjustment.
Solution Approach 2:
The adjustment knobs serve as intermediaries between the user and the lens positioning system. Rather than directly manipulating the lens, the user operates the adjustment knobs which then translate the lens to the desired position. This intermediary mechanism simplifies user interaction while managing the complexity of the translation system.

AI summary
A lamp including a lamp body, a light source plate provided in the lamp body and having a plurality of LED lamp beads; a lens plate provided above the light source plate and having several rows of dimming lenses; a surface cover located above the lens plate and connected to the lamp body; and adjustment knobs configured to adjust a position of the lens. The lens plate may be moved by rotating the adjustment knobs so that the position of the dimming lenses relative to the LED lamp beads is changed, thereby adjusting the light-emitting angle of the lamp.
