Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing vehicle remote door lock control apparatus faces issues with antennas being displaced and harnesses being damaged due to external forces, leading to potential contact with nearby members and breakage.
Innovation Solution
An electronic component attachment structure for a vehicle that includes a rear bumper with a panel wall and a fixing member with a front and upper wall, securing electronic components to prevent displacement and damage, while minimizing harness length and area exposed to external forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple antennas are arranged in a distributed manner on the rear bumper to improve radio communication coverage, then the radio wave propagation is improved, but the harness length and layout area increase
Solution Approach 1:
A harness routing guide structure is introduced as an intermediary component to manage and route the harnesses connecting distributed antennas to the control unit. This guide structure provides designated pathways that optimize harness routing, reduce unnecessary harness length, and prevent harness entanglement while maintaining the distributed antenna configuration for improved radio coverage.
2Reliability
If multiple antennas are arranged in a distributed manner on the rear bumper to improve radio communication coverage, then the radio wave propagation is improved, but the harness layout area increases
Solution Approach 1:
The harness routing guide structure serves as a space-efficient intermediary that consolidates harness routing into organized pathways. This reduces the overall layout area required for harnesses by preventing random dispersion and ensuring compact, structured routing between the distributed antennas and the control unit.
3Ease of manufacture
If electronic components are fixed directly to the rear bumper, then the installation is simple, but the components may be displaced by external forces and contact nearby members
Solution Approach 1:
A component mounting structure with positioning protrusions and corresponding recesses is implemented beforehand to prevent displacement. This pre-designed mechanical interlocking system absorbs and distributes external forces before they can cause component displacement or contact with nearby members, while maintaining relatively simple installation procedures.
4Ease of manufacture
If electronic components are fixed directly to the rear bumper, then the installation is simple, but the harnesses may be held between the bumper and skeleton components and damaged
Solution Approach 1:
The harness routing guide structure acts as a protective intermediary between the rear bumper and the harnesses. It provides dedicated routing channels that prevent harnesses from being pinched or damaged by compression between the bumper and skeleton components, while maintaining installation simplicity through integrated design.

AI summary
Provided is an electronic component attachment structure for a vehicle that allows electronic components to avoid contact with other nearby members due to displacement of the electronic components when an external force is transmitted to the electronic component side, while preventing breakage of harnesses. [Means to Solve the Problems]An electronic component attachment structure for a vehicle (100) according to the present invention includes: a rear bumper (102) of a vehicle; a plurality of electronic components (104, 106, and 108); and a fixing member (110) fixing the plurality of electronic components to the rear bumper. The rear bumper has: a panel wall (112) arranged at a rear end of the vehicle; and a bottom wall (114) extending from a lower end (116) of the panel wall to a front side of the vehicle. The fixing member has: a front wall (136) separated, to the front side of the vehicle, from the panel wall and facing the panel wall, the front wall (136) being joined to the bottom wall; and an upper wall (138) extending from an upper end of the front wall to the rear side of the vehicle and joined to the panel wall, the upper wall (138) linking the panel wall to the front wall.
