Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional bed frames lack protection against accidental toe stubbing and provide inadequate lighting in dark environments, making it difficult for users to navigate around the bed legs, especially at night or when cleaning.

Innovation Solution

A decorative bed leg cover with a built-in light-emitting device and proximity sensor that illuminates the area around the bed leg, featuring a deformable material construction to accommodate different leg shapes without altering its outer appearance, and a housing for the sensor and LED that can be easily mounted and operated.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If a rigid bed frame leg is used, then structural strength is improved, but user safety deteriorates due to risk of injury from accidental contact

Engineering Contradiction:

Improvestructural strengthVSAvoidinjury risk

Core Design Contradiction:

StrengthVSObject-affected harmful factors

Solution Approach 1:

The patent applies this principle by covering the rigid metal bed frame leg with a flexible cover made of soft material. The cover acts as a flexible shell that maintains the structural integrity of the rigid leg while providing a soft outer surface that prevents injury upon accidental contact. This resolves the contradiction by decoupling the structural function (handled by the rigid leg) from the safety function (handled by the flexible cover).

Inventive Principle:

Principle #30Flexible shells and thin films

2Illumination intensity

If ambient lighting is improved, then visibility is improved, but energy consumption increases

Engineering Contradiction:

ImprovevisibilityVSAvoidenergy consumption

Core Design Contradiction:

Illumination intensityVSUse of energy by moving object

Solution Approach 1:

The patent applies this principle by using a motion-activated lighting system that illuminates only when needed (when motion is detected near the bed). The light turns on periodically in response to user presence and turns off when no motion is detected, providing necessary visibility while minimizing continuous energy consumption. This resolves the contradiction by making lighting conditional rather than continuous.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The patent applies this principle by implementing an automatic motion-sensing system that detects user presence and activates lighting without requiring manual intervention. The system serves itself by automatically turning lights on when needed and off when not needed, optimizing energy usage based on actual requirements rather than continuous operation.

Inventive Principle:

Principle #25Self-service

3Ease of manufacture

If the bed frame leg structure is simplified, then manufacturing ease is improved, but adaptability deteriorates due to inability to accommodate different leg shapes

Engineering Contradiction:

Improvemanufacturing easeVSAvoidaccommodation of different leg shapes

Core Design Contradiction:

Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The patent applies this principle by using a foam material that can change its physical parameters (shape, density) during manufacturing. The foam is molded into different configurations to accommodate various leg shapes and sizes. This allows a single manufacturing process to produce adaptive covers for different bed frame leg types, resolving the contradiction between manufacturing simplicity and adaptability.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent applies this principle by combining foam material with fabric covering to create a composite structure. The foam provides adaptability and shock absorption, while the fabric provides durability and aesthetic appearance. This composite construction maintains manufacturing simplicity while achieving versatility in accommodating different leg shapes through the foam's moldable properties.

Inventive Principle:

Principle #40Composite materials

AI summary

A decorative bed leg cover for a bed frame and at least one perpendicularly and downwardly-extending bed leg that is disposed in a substantially vertical position, the bed leg cover having a visually pleasing aesthetic appearance together with a substantially vertically-disposed aperture disposed within the bed leg cover body for receiving the bed leg within the bed leg cover body. The bed leg cover also includes a bed leg cover sidewall, a recess defined within the bed leg cover sidewall, and a light/sensor housing that is removably disposed within the recess of the bed leg cover sidewall, the light/sensor housing comprising circuitry between a proximity sensor and a light-emitting device.
