Lockbox Removable Lower Housing for Accessible Battery Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lockboxes are difficult to replace batteries, leading to unnecessary disposal and waste due to the battery's inaccessible location.
Innovation Solution
A lockbox design with a primary battery located in a removable lower housing that allows easy access for replacement, utilizing a solenoid mechanism for securing and releasing the battery holder, and incorporating a backup battery for continued operation when the primary battery is depleted.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the battery is located inside the lockbox chassis, then the lockbox structure is compact and secure, but the battery becomes inaccessible and difficult to replace
Solution Approach 1:
The lockbox is divided into a fixed upper housing and a removable lower housing. The battery is placed in the removable lower housing, which can be detached from the fixed upper housing. This segmentation allows the battery to be accessed and replaced by simply removing the lower housing, without affecting the overall compact structure when assembled.
Solution Approach 2:
The lower housing is designed to be dynamically removable and reattachable to the upper housing through a solenoid-locked mechanism. This dynamic design allows the battery compartment to transition between a secure integrated state during operation and an accessible separated state during battery replacement.
2Reliability
If a solenoid mechanism is used to secure the removable housing, then the battery holder is securely locked, but the device complexity increases
Solution Approach 1:
The solenoid mechanism is integrated into the lower housing itself, combining the locking function with the housing structure. The solenoid's plunger engages with slots in the housing to secure it to the upper housing, eliminating the need for separate locking components and reducing overall device complexity.
Solution Approach 2:
The solenoid mechanism is powered by the battery it protects, creating a self-service system where the battery provides power to secure itself within the lockbox structure. This eliminates the need for external power sources or complex mechanical locking systems.
3Ease of operation
If the primary battery is made removable with a battery holder, then battery replacement becomes easy, but the risk of power loss during operation increases
Solution Approach 1:
The system includes a backup battery pre-positioned in the fixed upper housing that automatically engages when the lower housing with the primary battery is removed. This preliminary arrangement ensures that power supply is maintained without interruption during battery replacement operations.
Solution Approach 2:
The system transitions from a single battery design to a dual-battery design where the old battery can be discarded (removed with the lower housing) while a new battery is installed, and the backup battery serves as a safety net during this transition period.

AI summary
A lock box includes: a chassis; a lower housing solenoid attached to the chassis; a removable lower housing removably connected to the chassis through the lower housing solenoid; and a battery holder configured to removably secure a primary battery within the battery holder, such that the primary battery is configured to move with the removable lower housing, the primary battery being configured to provide electricity to the lower housing solenoid.
