Seat for saddle riding-type vehicle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The accuracy of temperature detection by the temperature sensing element in a saddle-ride vehicle seat is compromised when it is spaced from the heater wire, and the element is prone to damage or discomfort for the occupant due to direct contact.
Innovation Solution
The temperature sensing element is positioned in the front portion of the seat, within a recess, and integrated with the heater wire on a base fabric, protected by a flexible plate-shaped member, and connected via a harness through the seat components to minimize occupant contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the temperature sensing element is disposed in the vicinity of the heater wire, then the temperature detection accuracy is improved, but the temperature sensing element is prone to receive load from the occupant causing damage or discomfort
Solution Approach 1:
A recess is formed in the pad at the front portion, and the temperature sensing element is disposed in this recess. The recess acts as an intermediary structure that positions the temperature sensing element close to the heater wire for accurate temperature detection, while simultaneously protecting it from direct contact with the occupant's body, thus preventing damage and discomfort.
2Reliability
If the temperature sensing element is spaced from the heater wire, then the temperature sensing element is protected from load, but the temperature detection accuracy is lowered
Solution Approach 1:
The temperature sensing element is positioned in the front portion of the pad, while the heater wire is positioned in the rear portion. By utilizing the front-rear dimension of the pad, the invention achieves both close proximity for accurate temperature detection and spatial separation to prevent direct contact with the occupant, resolving the contradiction between measurement precision and reliability.
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
The temperature sensing element effectively detects heater wire temperature without damage or discomfort, ensuring accurate control and comfort for the occupant.
Implementation Method 1
a heater (20) provided on an upper portion of the pad (32), wherein the heater comprises a base fabric (61) extending in a front-rear direction on the upper portion of the pad (32), a heater wire (62) provided on the base fabric (61)
Implementation Method 2
In the control of the heater provided in the seat, namely, in the control of energization of the heater wire configuring the heater, a temperature sensing element such as a thermistor may be used. The temperature sensing element is an element whose characteristics change depending on the temperature.
