Lateral Battery Compartment Flap for Construction Site Lights

Solution Overview

Problem

Existing construction site lights require detachment from beacons or fences for battery replacement, making the process cumbersome and time-consuming.

Innovation Solution

The battery compartment flap is laterally arranged on the battery housing, allowing access for battery change without detaching the light, and can be lockable and designed as a slide-in unit for improved handling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the battery compartment is located at the bottom of the battery housing, then the light can be securely attached to beacons or fences, but the light must be detached to change the battery

Engineering Contradiction:

Improveattachment securityVSAvoidbattery replacement convenience

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The battery housing is segmented into functionally independent zones: the attachment interface remains at the bottom for secure mounting, while the battery compartment is separated and positioned laterally at the front. This segmentation allows the attachment mechanism and battery access to operate independently, resolving the contradiction between secure attachment and easy battery replacement.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The battery compartment is repositioned from the vertical bottom dimension to the lateral front dimension of the battery housing. This dimensional change allows simultaneous access to the battery compartment while the light remains attached to the beacon or fence, eliminating the need for detachment during battery replacement.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Ease of operation

If the flap is made large for convenient battery access, then battery replacement is easier, but the flap becomes more visible and susceptible to damage or vandalism

Engineering Contradiction:

Improvebattery access convenienceVSAvoidvandalism susceptibility

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The flap is positioned at the front lateral side of the battery housing, creating a localized access point that is functionally adequate but visually less prominent than a bottom-mounted flap. This local quality adjustment balances accessibility with reduced visibility, mitigating vandalism susceptibility while maintaining operational convenience.

Inventive Principle:

Principle #3Local quality

3Stability of the object's composition

If the light is securely screwed to the beacon or fence, then the attachment is stable, but the light must be unscrewed to change the battery

Engineering Contradiction:

Improveattachment stabilityVSAvoidbattery replacement time

Core Design Contradiction:

Stability of the object's compositionVSLoss of time

Solution Approach 1:

The battery housing is segmented into functionally independent zones: the attachment interface remains at the bottom for secure mounting, while the battery compartment is separated and positioned laterally at the front. This segmentation allows the attachment mechanism and battery access to operate independently, resolving the contradiction between secure attachment and easy battery replacement.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The battery compartment is repositioned from the vertical bottom dimension to the lateral front dimension of the battery housing. This dimensional change allows simultaneous access to the battery compartment while the light remains attached to the beacon or fence, eliminating the need for detachment during battery replacement.

Inventive Principle:
