Solution Overview

Problem

Many battery cases for light-fixtures require users to disassemble multiple components for battery replacement, which is time-consuming and prone to damage the case.

Innovation Solution

A battery case design featuring a sliding slot and locking slot, with a holder that includes a body portion, locking portion, and drawer, allowing for easy sliding and locking of the battery, and a clamping slot with elastic arms for secure fixation, along with a handle and intuitive operation via a flipping mechanism.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional battery case designs are used, then the case structure is simple, but battery replacement requires disassembling multiple components which is time-consuming and complex

Engineering Contradiction:
Improvebattery replacement operationVSAvoidbattery replacement time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The holder is divided into distinct functional components: a body portion for mounting, a locking portion for securing, and a drawer for easy removal. This segmentation allows the battery to be quickly accessed and replaced by operating only the drawer component rather than disassembling the entire case.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The locking portion is designed to transition between locked and unlocked states through a flipping motion. This dynamic mechanism allows the battery holder to be quickly secured or released by simply flipping the locking portion, enabling rapid battery replacement without complex operations.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If multiple components are disassembled for battery replacement, then the battery can be accessed, but the case is prone to damage and the operation is complex

Engineering Contradiction:
Improvebattery replacement operationVSAvoidcase durability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

By segmenting the holder into a body portion, locking portion, and drawer, the design isolates the replacement operation to only the drawer component. The main case structure remains intact and undisturbed, preventing damage to the case while still enabling easy battery access.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The drawer is designed to automatically engage with the body portion and can be easily pulled out for battery replacement without requiring tools or complex operations. This self-service mechanism reduces the risk of user error and case damage while simplifying the replacement process.

Inventive Principle:
Principle #25Self-service

3Reliability

If the body portion is slid into the sliding slot, then the battery is securely locked, but the battery needs to be removed for replacement

Engineering Contradiction:
Improvebattery fixation stabilityVSAvoidbattery removal operation
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The locking portion is designed to transition between locked and unlocked states through a simple flipping motion. When flipped to the locked position, it secures the body portion in the sliding slot; when flipped to the unlocked position, it releases the body portion for easy removal via the drawer.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The drawer acts as an intermediary component between the user and the battery. Instead of directly manipulating the locked body portion, the user pulls the drawer to initiate battery removal, which then triggers the locking mechanism to release, making the removal process easier and more intuitive.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A battery case for a light-fixture includes a case body and a holder. The case body is provided with a sliding slot and a locking slot, the sliding slot communicates with an outer side of the case body, the holder includes a body portion, a locking portion and a drawer, the locking portion and the drawer are respectively connected to the body portion, and the body portion is slidably mounted on the sliding slot and is used for mounting a battery; when the body portion is completely slid into the sliding slot, the locking portion is snapped into the locking slot; the locking portion is flipped to be disengaged from the locking slot and operate the drawer, so that the body portion is slid out of the sliding slot; the design of flipping the locking portion provides an intuitive operation mode for a user.
