Instrument Panel Reinforcement Mounting via Insertion Piece
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing installation structure of instrument panel modules for vehicles is complex and time-consuming due to the need for precise positioning and engagement of side brackets and pins, which complicates the process of mounting the instrument panel reinforcement.
Innovation Solution
A mounting structure for instrument panel reinforcement that includes a receiving portion on the vehicle body skeleton and an insertion piece on the instrument panel reinforcement, allowing for easy alignment and fixation by restricting displacement and rotation, thereby simplifying the positioning process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If engaging pins are disposed apart in the vehicle vertical direction and engaging concave portions are formed in correspondence, then the instrument panel reinforcement can be securely engaged to the vehicle body skeleton, but the positioning work becomes complex and time-consuming
Solution Approach 1:
The patent combines multiple engagement functions into a single insertion piece. The insertion piece integrates both vertical and horizontal engagement capabilities, allowing the instrument panel reinforcement to be secured to the vehicle body skeleton in one operation rather than requiring separate engagement steps for multiple pins. This merging of functions simplifies the positioning process while maintaining secure engagement.
Solution Approach 2:
The insertion piece acts as an intermediary element between the instrument panel reinforcement and the vehicle body skeleton. It provides a simplified interface that mediates the connection, replacing the complex multi-pin engagement system with a single insertion mechanism that achieves the same secure attachment function.
2Stability of the object's composition
If multiple engaging pins and concave portions are used for secure fixation, then the instrument panel reinforcement is stably mounted, but the installation process becomes complex and requires multiple steps
Solution Approach 1:
The patent merges multiple engagement functions into a single insertion piece structure. The insertion piece simultaneously provides vertical positioning, horizontal positioning, and secure fixation capabilities that would otherwise require multiple separate pins and concave portions. This reduces the installation structure complexity while maintaining mounting stability.
Solution Approach 2:
The insertion piece is designed with segmented functional zones that perform different engagement tasks. The insertion piece includes an insertion portion for vertical engagement and a protruding portion for horizontal engagement, allowing it to segment the engagement functions spatialally while maintaining a unified structure.
3Reliability
If the instrument panel reinforcement is positioned by rotating around an upper engaging pin as fulcrum, then the lower engaging pin can be engaged, but the positioning work becomes complex and time-consuming
Solution Approach 1:
The patent combines the positioning and engagement actions into a single simultaneous operation. The insertion piece is designed to engage both vertical and horizontal positions in one insertion motion, eliminating the need for separate rotation and engagement steps. This merging of actions significantly reduces the time required for complete positioning while ensuring reliable engagement.
Solution Approach 2:
The insertion piece is pre-configured with the correct geometry and orientation to automatically achieve proper positioning upon insertion. The preliminary design of the insertion piece's shape and engagement surfaces ensures that the instrument panel reinforcement is correctly positioned without requiring manual rotation or adjustment during installation.

AI summary
Due to an insertion piece being inserted in a receiving portion, displacement of an instrument panel R/F with respect to a vehicle body in two directions that are orthogonal to a direction of insertion of the insertion piece into the receiving portion is restricted. Further, due to the insertion piece being inserted in the receiving portion, rotation of the instrument panel R/F around the direction of insertion of the insertion piece into the receiving portion is restricted. Therefore, as the insertion piece is inserted into the receiving portion at the time of installing the instrument panel R/F at the vehicle body, the instrument panel R/F can be positioned simultaneously with moving while being guided along the direction of insertion of the insertion piece into the receiving portion.
