Floating RV Holding Mount for Tolerance-Compensated Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing recreational vehicle components, such as mobile homes and caravans, face challenges in accommodating manufacturing-related tolerances during the installation of add-on parts like rear lights, which often require precise alignment and stability, but current fastening concepts are limited in compensating for these tolerances and ensuring mechanical stability.
Innovation Solution
A holding device with a bearing element, a floating receiving element providing two translational degrees of freedom, and a connecting element with a pivoting head, allowing for alignment compensation in multiple directions and featuring a conical receiving element and a cylindrical sliding disk for enhanced stability and mobility, along with a fastening section for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a rigid fastening concept is used to ensure mechanical stability, then stability is improved, but installation tolerances are reduced and assembly becomes difficult
Solution Approach 1:
The receiving element is designed to move dynamically relative to the bearing element during assembly, transitioning from a movable state that accommodates tolerances to a fixed state that provides stability. This dynamic capability allows the system to adapt to manufacturing variations while maintaining final structural integrity.
Solution Approach 2:
The system changes the degree of freedom parameter during assembly - starting with multiple degrees of freedom to accommodate tolerances, then reducing to fewer degrees of freedom in the final assembled state to provide mechanical stability. The receiving element's movement capability enables this parameter transition.
2Ease of operation
If a movable receiving element is used to accommodate tolerances, then ease of assembly is improved, but mechanical stability may be compromised
Solution Approach 1:
The receiving element's movement is not permanent but temporary - it provides dynamic adjustment capability during assembly to ease installation, then transitions to a stable fixed position in the final assembly. The system maintains stability by designating specific stop positions or engagement points that prevent excessive movement in the assembled state.
Solution Approach 2:
The receiving element is pre-designed with specific movement capabilities and stop positions that guide the assembly process. The preliminary movable state facilitates easy insertion and alignment, while the predetermined stop positions ensure the component settles into a stable final position with appropriate mechanical engagement.
3Stability of the object's composition
If precise alignment is required for component installation, then mechanical stability is improved, but assembly time and complexity increase
Solution Approach 1:
The holding device performs self-alignment through the receiving element's movement capability. During assembly, the receiving element automatically adjusts its position to accommodate tolerances and achieve proper alignment without requiring external adjustment tools or procedures. The component essentially aligns itself as it is inserted and settles into the bearing element.
