Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing photo-electric control testers do not effectively create a barrier between ambient light and larger sensors, leading to incomplete coverage and inaccurate testing results.

Innovation Solution

A cover comprising a hood and a baffle with adjustable end portions and shoulders, which surrounds the sensor to create a comprehensive barrier against ambient light, allowing for effective testing of sensors of varying sizes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If existing photo-electric control testers are used, then testing can be performed on standard sensors, but larger sensors cannot be completely covered and tested accurately

Engineering Contradiction:

Improvesensor size compatibilityVSAvoidtesting accuracy

Core Design Contradiction:

Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The baffle includes movable end portions that can be adjusted between spaced apart and overlapped positions, allowing the cover to adapt to different sensor sizes. This dynamic adjustment capability enables the same cover design to accommodate both standard and larger sensors effectively.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The cover is divided into distinct functional components: a hood for covering the sensor and a baffle with movable end portions for adjusting the barrier. This segmentation allows each component to be optimized independently for its specific function while working together to solve the size adaptability problem.

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If a fixed-size cover is used, then the structure is simple, but it cannot provide complete coverage for larger sensors

Engineering Contradiction:

Improvesensor size coverageVSAvoidcover structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The baffle incorporates movable end portions that can be positioned to overlap, creating an adjustable barrier. This dynamic feature allows the cover to expand its coverage capability without requiring multiple different cover sizes, balancing adaptability with structural efficiency.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The movable end portions of the baffle can be nested or overlapped within each other's spatial envelope when adjusted, allowing the cover to maintain a compact form while providing variable coverage sizes through the overlapping configuration.

Inventive Principle:

Principle #7Nested doll (Nesting)
