Recessed Button Lighting Module Prevents Accidental Activation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wearable and attachable lighting devices lack a secure and easy-to-use design for activation and charging, with potential for accidental activation and difficulty in preventing removal from mounting devices.
Innovation Solution
A lighting module and device design featuring a module frame and circuit board with a recessed button, a rechargeable battery, and a charging port, where the module frame includes a lip for secure attachment and a cap with a raised portion to prevent accidental activation, and a device body with a cavity and supports to protect the lighting module and facilitate easy insertion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the button is made accessible on the module frame, then the lighting device can be easily activated, but the device may be accidentally activated
Solution Approach 1:
The button is nested within a recess in the module frame, creating a protected access point that requires intentional insertion of a protrusion (such as a finger or tool) to activate. This nesting structure maintains ease of operation while preventing accidental activation from external contact.
Solution Approach 2:
A protrusion element acts as an intermediary between the user's finger and the button. The protrusion must be deliberately inserted into the recess to reach and press the button, providing a controlled activation mechanism that prevents accidental operation while maintaining user-friendly operation.
2Reliability
If the lighting module is securely attached to the device, then the device remains firmly mounted, but the module cannot be easily removed for charging
Solution Approach 1:
The attachment mechanism uses dynamic characteristics where the lighting module can be easily inserted into the device body through a recess, but removal requires deliberate action. The spring-loaded or friction-fit connection provides secure attachment during use while allowing controlled removal for charging purposes.
Solution Approach 2:
The device is segmented into separable components: the lighting module can be independently removed from the device body by disengaging from the recess. This segmentation allows the module to remain securely attached during operation while enabling easy removal for charging without requiring tool intervention.
3Ease of operation
If the button is exposed on the module frame, then the button can be easily pressed, but the button may be inadvertently activated
Solution Approach 1:
The button is nested within a recess that requires a protrusion element to access. This nested configuration allows intentional button pressing while preventing inadvertent activation from accidental contact with the module frame surface.
Solution Approach 2:
The recess structure creates a preliminary barrier that prevents accidental button activation. The protrusion must be deliberately inserted past this barrier to reach the button, providing preliminary protection against harmful inadvertent activation while maintaining ease of intentional operation.
