Remote Battery Door Button With Two-Phase Child-Resistant Unlocking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote control devices lack a locking mechanism for battery compartments, posing risks such as choking hazards for small children and user frustration due to the need for specialty tools, while maintaining ease of battery replacement.
Innovation Solution
A two-phase activation system for the remote battery door button, comprising an outer and inner lock button with a compression member, where the inner lock button rotates and depresses to unlock, using common tools like coins or screwdrivers, ensuring secure battery compartment access without complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a locking mechanism is added to the battery compartment, then security against unauthorized access (especially by children) is improved, but device complexity and difficulty of operation increase
Solution Approach 1:
The locking mechanism is divided into two distinct phases: an inner button that must be depressed first to release the latch engagement, and an outer button that must then be depressed to release the battery door. This segmentation creates a two-step process that is more secure than a single-button mechanism but remains manageable for users.
Solution Approach 2:
The inner lock button is nested within the outer lock button, creating a concentric arrangement where the smaller inner button is housed inside the larger outer button. This nested structure allows both control elements to be integrated into a single compact interface on the remote control device.
2Object-affected harmful factors
If a locking mechanism with key is added, then security is improved, but loss of key renders the device worthless and specialty tools are difficult to locate
Solution Approach 1:
The locking mechanism is designed to be self-operating through the two-button system that uses the device's existing structure and components. The inner and outer buttons work together with the latch and spring mechanism to provide security without requiring external keys or specialty tools, making the system self-sufficient and always accessible to the user.
3Ease of operation
If a simple battery door without locking mechanism is used, then ease of operation is improved, but security and prevention of unauthorized access deteriorates
Solution Approach 1:
The locking mechanism incorporates dynamic elements including a spring-loaded latch that can engage and disengage, and two buttons that provide sequential activation. The system transitions between locked and unlocked states through controlled mechanical movement, providing security while maintaining operational flexibility.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system provides a balance between security and user convenience by allowing easy battery replacement while preventing unauthorized access, particularly by small children, without requiring specialty tools.
Implementation Method 1
the compression member is initially compressed, but provides resistance that pushes the outer lock button back into its original position after the depress force is removed

AI summary
A system for a remote battery door button is disclosed. The system includes: a holder bracket, a compression member, an outer lock button, and an inner lock button. The outer lock button has a lower surface that rests upon the compression member. The outer lock button being depressible by compressing the compression member against the holder bracket. The outer lock button includes a hook latch that selectively secures to a fixed latch to secure a remote battery door to a remote body. The inner lock button is seated within the outer lock button, and is rotatable within the outer lock button. A lower surface of the inner lock button includes protrusions that protrude into the openings of the holder bracket when the inner lock button is depressed in the unlocked position, and unlatches the hook latch of the outer lock button from the fixed latch.
