Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional power generator devices used in switches struggle to generate a stable induced electromotive force due to inconsistencies in rotational speed and insufficient operating force, especially when operated by hand.
Innovation Solution
A power generator device incorporating a case, an operating member, a power generator part, an elastic part, and a connection disengagement mechanism that accumulates and outputs elastic force to drive the power generator, ensuring stable power generation regardless of the operator's force.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a shaft connected to the coil is rotated at high rotational speed to generate stable induced electromotive force, then power generation stability is improved, but the device becomes difficult to operate with finger force and requires high operating force
Solution Approach 1:
The elastic part accumulates elastic force in advance during the operation of the operating member, so that when the operating member is released, the stored elastic force can instantaneously drive the driven part to rotate at high speed, generating stable induced electromotive force without requiring continuous high operating force
Solution Approach 2:
The connection disengagement mechanism periodically engages and disengages the operating member with the elastic part, creating a periodic cycle of force accumulation and release that converts continuous finger pressure into intermittent high-speed rotation for stable power generation
2Ease of operation
If the shaft rotational speed varies due to operator discrepancies, then ease of operation is improved, but power generation stability deteriorates
Solution Approach 1:
The elastic part serves as a buffer that accumulates energy during operation and releases it in a controlled manner, standardizing the rotational speed of the driven part regardless of variations in operator speed, thus ensuring stable induced electromotive force while maintaining ease of operation
Solution Approach 2:
The elastic part acts as an intermediary between the operating member and the driven part, decoupling the operator's variable-speed input from the power generator's requirement for consistent high-speed rotation, thereby resolving the contradiction between operational flexibility and power generation stability

AI summary
A power generator device includes a switch lever that is operated upon power generation, a power generator that generates an induced electromotive force when a driven unit is driven; and a power generation spring that accumulates an elastic force upon being applied an external force and outputs the accumulated elastic force to drive the driven unit. Further, the power generator device includes a sliding member and a pinwheel that are configured to transmit an operating force of the switch lever to the power generation spring while the switch lever is positioned between a pre-operation position and an accumulation complete position at which a predetermined elastic force is accumulated at the power generation spring, and disengage the engagement between the switch lever and the power generation spring and allow the power generation spring to output the accumulated elastic force when the switch lever moves past the accumulation complete position.
