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 connected to an external rubber button.
Innovation Solution
A cordless lamp design featuring a button assembly with a flexible piece and a rigid piece to prevent accidental activation, along with a protective cover to prevent inadvertent switching, and a circuit board with charge and discharge management modules for power control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a tact switch connected to an external rubber button is used for the cordless lamp, then the lamp can be easily activated by gentle touching, but the lamp may be accidentally turned on during handling and transportation, causing power loss
Solution Approach 1:
The button is nested within a protective cover that can slide over it. The protective cover is sleeved on another end of the button and abutted against a sidewall of the housing, creating a nested structure where the button is protected from accidental contact during handling and transportation while remaining accessible when needed
2Ease of operation
If the button is exposed for easy access, then the lamp can be quickly turned on, but the button may be accidentally pressed during product handling and transportation
Solution Approach 1:
The protective cover acts as an intermediary element between the external environment and the button. It can be slid over the button to protect it from accidental pressing during handling and transportation, while allowing intentional activation when the cover is moved aside
