Ultrasonic Sensor Attachment Component for Vehicle Bumper
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ultrasonic sensor retainers face installation challenges due to spatial restrictions in vehicular bumpers, often resulting in limited positioning options or weak fixing strength, particularly when rectangular or small-end-face designs are used.
Innovation Solution
An attachment component with a center attachment part and removable attachment pieces, featuring cuttable sections that allow for flexible configuration and enhanced versatility, including a rectangular shape with flat plate or triangular attachment pieces and thin-walled linear grooves, enabling easy adjustment and secure attachment to the bumper.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a retainer with attaching portions of substantially rectangular shape is used, then the fixing strength to bumper is improved, but the installing position is severely restricted due to abutment against radiator, reinforcing member, fog lamp, etc.
Solution Approach 1:
The attachment portion is divided into a center attachment part and multiple attachment pieces connected via cuttable sections. This segmentation allows selective removal of attachment pieces that would abut against surrounding components, enabling installation in previously restricted positions while maintaining adequate fixing strength with the remaining attachment pieces.
Solution Approach 2:
The attachment component transitions from a fixed rectangular configuration to a dynamic configuration where attachment pieces can be selectively removed. This dynamic adaptability allows the same component to be customized for different installation positions and vehicle configurations, resolving the contradiction between fixing strength and position flexibility.
2Adaptability or versatility
If the end face is formed small to reduce restriction on installing position, then the installing position flexibility is improved, but the fixing strength becomes low resulting in possible detachment
Solution Approach 1:
Instead of uniformly reducing the end face size, the invention segments the attachment portion into a center part and removable pieces. This allows the center attachment part to provide stable fixation while individual attachment pieces can be removed to achieve position flexibility, avoiding the detachment issue associated with uniformly small end faces.

AI summary
Provided is a highly versatile attachment component corresponding to a space around an attachment location of a vehicular member. A retainer for attaching an ultrasonic sensor to a vehicle has a member holding portion for holding the ultrasonic sensor; and an attachment portion that is to be attached to the vehicle. The attachment portion has a center attachment part; a plurality of attachment pieces which are an upper attachment piece, a lower attachment piece, a left attachment piece and a right attachment piece; and cuttable sections joining the center attachment part and the multiple attachment pieces. These attachment pieces can be removed by cutting the cuttable sections. Therefore, some of the attachment pieces may be removed so as to secure a space around a location to which the ultrasonic sensor is to be attached, thus allowing the ultrasonic sensor to be attached to the vehicle.
