Protector Member Attachment Structure for Vehicle Reinforcement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicle reinforcement structures experience significant dimension errors in the width direction, leading to reduced positional accuracy of the protector member attachment, affecting the relative positioning between the protector member and the bumper.
Innovation Solution
An attachment structure for the protector member that includes a resin-made protector positioned between the reinforcement and the bumper, with a fastening mechanism allowing longitudinal displacement to adjust the attachment position, utilizing elongated holes and a resin-made clip to ensure accurate positioning and reduce operational load.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a simple rectangular tube shape reinforcement is used, then manufacturing is easier and cost is lower, but dimension errors occur in the width direction reducing positional accuracy
Solution Approach 1:
The attachment structure incorporates adjustability in the longitudinal direction, allowing the protector member to be dynamically repositioned to compensate for dimension errors in the reinforcement, thereby maintaining attachment position accuracy despite manufacturing variations
Solution Approach 2:
The invention changes the attachment position parameter in the longitudinal direction to compensate for width direction dimension errors, allowing the protector member to be attached at different positions along the longitudinal axis to achieve accurate positioning relative to the bumper
2Stability of the object's composition
If the protector member is rigidly fixed to the reinforcement, then structural stability is improved, but adjustment for dimension errors becomes difficult
Solution Approach 1:
The attachment structure transitions from a rigid fixed connection to a dynamic adjustable connection, enabling the protector member to be positioned and secured at optimal locations while maintaining structural stability through proper fastening mechanisms
Solution Approach 2:
The attachment structure is segmented into adjustable components including the fastening member and attachment holes, allowing independent adjustment of the protector member position while maintaining overall structural integrity through the fastening connection
