Twin Throttle Body Wiring Layout for Compact Motor Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional throttle devices require additional space and weight due to separate installation of wiring base members and bolts for each motor, leading to increased size and cost.
Innovation Solution
A throttle device design where the wiring base member is compactly placed between the gear cases of two facing throttle bodies, eliminating the need for dedicated bolts and reducing the device's size and weight by using a wiring base member with embedded wiring and metal collars for secure positioning and fastening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate wiring base members and bolts are installed for each motor in conventional throttle devices, then reliable electrical connectivity and secure fastening are achieved, but the device size and weight increase
Solution Approach 1:
The patent combines multiple separate components (wiring base members for two motors and associated bolts) into a single shared wiring base member that serves both motors. This merging eliminates redundant components, reducing overall device weight while maintaining reliable electrical connectivity to both motors through the unified wiring structure.
2Reliability
If separate wiring base members and bolts are installed for each motor in conventional throttle devices, then reliable electrical connectivity and secure fastening are achieved, but the device size increases
Solution Approach 1:
The patent merges separate wiring base members into a single unified component that accommodates both motors' wiring needs. This consolidation reduces the total area occupied by wiring components in the throttle device, while the unified structure maintains reliable electrical connections to both motors through integrated lead frame pathways.
3Strength
If dedicated bolts are used to fix wiring base members to each throttle body, then secure fastening is achieved, but device complexity and cost increase
Solution Approach 1:
The patent combines the function of multiple dedicated bolts into a single bolt that secures the unified wiring base member to the throttle body. This merging reduces the number of fixing members from multiple bolts to one, simplifying the assembly structure and reducing device complexity while maintaining adequate fastening strength through the centralized mounting point.

AI summary
Provided is a throttle device including two throttle bodies having motors that face to each other, in which the wiring base member is compactly placed. A throttle device 1 includes first and second throttle bodies 2 and 3. The first and second throttle bodies 2 and 3 each include a gear case 10 that houses a deceleration mechanism 9 that transmits the rotational force of the motor 8 to the throttle shaft 6. A wiring base member 7 having a power coupler 14 is fixed between the first and second throttle bodies 2 and 3 while being placed between these gear cases 10. The wiring base member 7 has wiring 32 embedded therein, the wiring 32 connecting the motor terminal 25 of each motor 8, the motor terminal 25 protruding into the gear case 10, and the power coupler 14.
