Cordless Lamp Button Cover to Prevent Accidental Switch Activation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cordless lamps can inadvertently turn on during handling and transportation, leading to power loss and affecting product quality due to the sensitivity of the tact switch.
Innovation Solution
A cordless lamp design featuring a button assembly with a protective cover and a rigid piece to prevent accidental activation, along with a charge and discharge module for power management, ensuring the lamp remains off during handling and expanding its usage by allowing charging of external devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the tact switch is made sensitive to enable easy operation, then the ease of operation is improved, but the reliability deteriorates due to accidental activation during handling and transportation
Solution Approach 1:
A protective cover is introduced as an intermediary component between the button and the external environment. The cover includes a button hole that allows the button to be pressed only when the cover is removed or opened, preventing accidental activation during handling and transportation while maintaining ease of operation during intended use
Solution Approach 2:
The button assembly is segmented into multiple components: the button itself, the protective cover, and a button hole. This segmentation allows the button to remain inactive during transportation (when cover is closed) and active during use (when cover is open), resolving the contradiction between sensitivity and accidental activation
2Ease of operation
If the button is exposed to allow easy pressing, then the ease of operation is improved, but the object-affected harmful factors worsen due to accidental touches during handling
Solution Approach 1:
The protective cover serves as a mediator that physically blocks external objects from accidentally touching the button during handling and transportation, while still allowing intentional operation when the cover is removed or opened
Solution Approach 2:
The protective cover is designed to be in place before handling or transportation occurs, providing preliminary protection against accidental button activation. The cover must be removed or opened before the button can be pressed, preventing harmful accidental activation in advance

AI summary
Provided is a cordless lamp including a housing, a light-emitting module (3), a switch (7), a button assembly (8), and a power supply (9). The housing defines a mounting cavity, and a sidewall of the mounting cavity is provided with a fitting hole. The light-emitting module (3) is arranged in the housing and includes a circuit board (32) and a light-emitting element (33) arranged on the circuit board (32). The switch (7) is arranged in the housing and electrically connected to the circuit board (32), and is used to control turning on and off of the light-emitting element (3) and provided with a trigger surface. The button assembly (8) includes a button (81) and a protective cover (82). The button (81) is inserted through the fitting hole, and one end of the button (81) is operative to abut the trigger surface. The protective cover (82) is sleeved on another end of the button (81), and abuts a sidewall of the housing. The power supply (9) is arranged in the housing and electrically connected to the circuit board (32).
