Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless switches require two separate operations to generate power for turn-on and turn-off functions, making them cumbersome to use.
Innovation Solution
A power generating device with a sliding member and elastic parts that allows for dual power generation with a single operation of the switch lever, utilizing a toggle mechanism and pinwheel spring to store and release elastic forces for efficient power generation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a dry cell is used as the power supply of the wireless switch, then the wireless switch can be powered, but it is troublesome to replace the dry cell, thus reducing the usability of the wireless switch
Solution Approach 1:
The wireless switch generates its own power through a power generating device that converts mechanical energy from switch operations into electrical energy, eliminating the need for external battery replacement and making the device self-sufficient
Solution Approach 2:
The patent replaces the chemical energy storage system (dry cell battery) with a mechanical-to-electrical energy conversion system, where manual operations are converted into electrical power through electromagnetic induction
2Productivity
If the conventional wireless switch generates the outputs of two switch operations separately, then each operation can be performed, but it is necessary to operate the operation knob of the wireless switch twice
Solution Approach 1:
The patent combines two separate power generation operations into a single continuous operation by implementing a bidirectional sliding mechanism that generates power in both directions during one lever operation cycle
Solution Approach 2:
The patent employs a dynamic mechanism where the sliding member can move bidirectionally to generate power, and the connecting member rotates forward and reverse to engage different elastic parts, allowing continuous power generation throughout the entire operation cycle
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
Enables improved operability by allowing power generation for both switch functions with a single operation, enhancing usability and reducing the need for frequent battery replacements.
Implementation Method 1
a power generating part configured to cause an induced electromotive force to be generated in response to a driving of a driven part thereof
Implementation Method 2
a first elastic part configured to be caused to store an elastic force by a movement of the sliding member in the first direction; a second elastic part configured to be caused to store an elastic force by a movement of the sliding member in the second direction; a third elastic part connected to the connecting member and configured to be caused to store an elastic force by the connecting member rotating with the movement of the sliding member in the second direction

AI summary
A power generating device includes a power generating part, a sliding member, first, second and third elastic parts, and a connecting member. When the sliding member is caused to move to a first storage completion position by an operation that causes the connecting member to rotate, the connecting member and the sliding member are disconnected so that the sliding member is caused to move in a first direction by an elastic force stored in the second elastic part. The connecting member is caused to rotate by an elastic force stored in the third elastic part. When the sliding member is caused to move to a second storage completion position by the third elastic part, the connecting member and the sliding member are disconnected so that the sliding member is caused to move in a second direction by an elastic force stored in the first elastic part.
