Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote control apparatuses for toilet seat water spray systems face challenges in balancing design quality and signal transmission accuracy, particularly when using smaller sub-buttons to generate electric power, which can result in insufficient power and degraded transmission accuracy.
Innovation Solution
A remote control apparatus with a configuration that minimizes mechanical energy loss in sub-buttons, allowing for high transmission accuracy by using a transfer mechanism that linearly transfers force to a power generation unit, enabling larger electric power generation and accurate signal transmission, even with smaller button sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If sub-buttons are formed in a relatively small size to enhance design quality and reduce remote controller size, then design quality is improved, but it becomes difficult to generate sufficient electric power, resulting in degradation in signal transmission accuracy
Solution Approach 1:
A transfer part (lever mechanism) is introduced as an intermediary between the sub-button and the power generation part. When a sub-button is pressed, the transfer part amplifies the input force and transfers it to the power generation part, enabling small buttons to generate sufficient electric power for accurate signal transmission without compromising design quality
Solution Approach 2:
The mechanical advantage ratio of the transfer part is designed to change the force parameter from the button press to the power generation input. By optimizing the lever arm lengths, the system transforms small button press forces into sufficient power generation forces, resolving the contradiction between small button size and adequate power generation
2Shape
If sub-buttons are formed in a relatively small size, then design quality is enhanced, but it becomes difficult for users to press them, worsening ease of operation
Solution Approach 1:
The transfer part serves as a mechanical intermediary that reduces the force required to press sub-buttons. By providing force amplification through the lever mechanism, users can easily press small sub-buttons without requiring excessive finger strength, thus maintaining both compact design and operational ease
Solution Approach 2:
The transfer part is designed with movable components that dynamically adjust the force distribution during button pressing. The lever mechanism provides mechanical advantage that makes pressing small buttons easier, allowing the system to maintain small button sizes while improving ease of operation
3Ease of operation
If main buttons are formed in a large size to facilitate easy pressing, then ease of operation is improved, but the overall remote controller size increases, affecting design quality
Solution Approach 1:
The button system is segmented into two functional groups: main buttons (large size for ease of operation) and sub-buttons (small size for compact design). The transfer part is selectively applied to sub-buttons, allowing the remote controller to have a compact overall size while maintaining ease of operation for critical functions through large main buttons

AI summary
An object of the present invention is to provide a remote control apparatus for a toilet seat apparatus which generates electric power by a user's pressing operation, the remote control apparatus being capable of balancing design quality and transmission accuracy of a signal at a high level.A remote control apparatus RC has a main button group MB, including a water spray button WB and a water stop button MB1, and a sub-button group SB, including a stronger button SB1, etc. Each button in the sub-button group SB has a circular shape with a diameter smaller than that of each button in the main button group MB from a front view. When a button in the main button group MB is pressed, mechanical energy is transferred to a power generation unit GU by a first slide member 10 and a second slide member 20. On the other hand, when a button in the sub-button group SB is pressed, mechanical energy is transferred only by the second slide member 20 and a loss in the mechanical energy in such situation is smaller than the situation where a button in the main button group MB is pressed.
