Solution Overview

Problem

Existing lampshade modules require multiple molds for different light projection angles, leading to increased manufacturing costs and inventory pressure, and are prone to water infiltration due to design gaps.

Innovation Solution

A modular lampshade system with a lens holder and interchangeable lenses, where the lens holder has recessed holes with buckle portions to securely hold lenses, allowing for adjustable light projection angles without remaking lenses and preventing water ingress.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple optical lampshades with different lens structures are manufactured for different projection angles, then various light projection angle requirements can be met, but manufacturing costs increase and inventory pressure increases

Engineering Contradiction:

Improvelight projection angle requirementsVSAvoidmanufacturing cost

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The optical lampshade is divided into two independent modules: a reusable lens holder and interchangeable lenses. The lens holder contains multiple lens holes that can accommodate different lenses with various projection angles. This segmentation allows the lens holder to be manufactured once and reused, while only the lenses need to be varied for different applications, significantly reducing manufacturing costs and inventory requirements.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The lens holder is designed as a universal component that can accommodate multiple types of lenses with different projection angles through its multiple lens holes. This multi-functional design allows a single lens holder to serve multiple purposes by simply changing the lenses, eliminating the need to manufacture separate lampshades for each projection angle requirement.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

Engineering Contradiction:

Improvelight projection angle requirementsVSAvoidinventory quantity

Core Design Contradiction:

Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

By segmenting the optical lampshade into a reusable lens holder and interchangeable lenses, the system reduces the total quantity of components that need to be inventoried. Instead of stocking multiple complete lampshades with different lens structures, only the varying lenses need to be kept in inventory, while the lens holder can be reused across different configurations.

Inventive Principle:

Principle #1Segmentation

3Reliability

If the optical lampshade is assembled with fixed lens portions, then the light projection angle is set, but rainwater can seep into the assembly gap

Engineering Contradiction:

Improvelight projection angle stabilityVSAvoidrainwater infiltration

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

A waterproof seal or gasket is introduced as an intermediary element between the lens holder and the lenses. This seal fills the assembly gap and prevents rainwater from seeping into the interface, while still allowing for the assembly and disassembly of the modular components. The seal acts as a mediator that maintains both the waterproof integrity and the modular replaceability of the system.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A lampshade module to be combined on a lamp to change the light projection angle of the lamp includes a lens holder having lens holes and first buckle portions at the hole wall of each lens hole for holding down the inserted lens, and a plurality of lenses each having a light entrance surface corresponding to the bottom end of one respective lens hole and an opposing light-emitting surface. The light entrance surface is a convex arc surface, and the arc of the convex arc surface is set according to the light projection angle required. In this way, the lenses with the appropriate projection angles can be selected and assembled in the lens holes, and then the lens holder can be assembled in the lamp.
