Solution Overview

Problem

Existing mounting structures for hidden vehicle door handles struggle to ensure uniform gaps and flushes between the handle and the vehicle door outer plate due to large element errors and limited adjustment capabilities.

Innovation Solution

A mounting mechanism comprising an outer plate mounting element, a base element, and tolerance absorption assemblies. The outer plate mounting element is disposed on the inner side of the vehicle door outer plate, the base element is connected to the handle and clamped to a designated position, and the tolerance absorption assemblies absorb manufacturing tolerances and connecting errors between the bolts and mounting holes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If handle bases are directly connected to mounting holes in vehicle door outer plate reinforcing plates by bolts, then the mounting structure is simple, but uniform gaps and flushes between handles and vehicle door outer plates cannot be ensured due to large element errors and limited adjustment capability

Engineering Contradiction:

Improveuniform gap and flush between handle and vehicle door outer plateVSAvoidmounting structure complexity

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The mounting structure is segmented into three functional modules: outer plate mounting element (for positioning on vehicle door outer plate), base element (for connecting handle), and tolerance absorption assembly (for absorbing mounting errors). This segmentation allows each module to perform its specific function optimally, achieving uniform gaps and flushes while managing complexity through functional decomposition

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The tolerance absorption assembly acts as an intermediary component between the outer plate mounting element and the base element. It absorbs mounting errors and tolerances, enabling precise positioning of the handle relative to the vehicle door outer plate without requiring direct precision mounting between all components

Inventive Principle:

Principle #24Intermediary (Mediator)

2Manufacturing precision

If handle mounting holes provide adjustment capability, then some gap adjustment is possible, but uniform flushes cannot be ensured due to limited adjustment amounts

Engineering Contradiction:

Improveuniform flush between handle and vehicle door outer plateVSAvoidadjustment capability

Core Design Contradiction:

Manufacturing precisionVSAdaptability or versatility

Solution Approach 1:

The tolerance absorption assembly serves as a mediator that provides comprehensive adjustment capability in multiple directions. It compensates for element errors and enables uniform flushes between the handle and vehicle door outer plate, overcoming the limited adjustment capability of traditional mounting hole designs

Inventive Principle:

Principle #24Intermediary (Mediator)

3Ease of manufacture

If larger element errors are present in mounting holes, then manufacturing is easier, but uniform gaps and flushes between handles and vehicle door outer plates cannot be achieved

Engineering Contradiction:

Improvemounting hole manufacturing toleranceVSAvoiduniform gap and flush between handle and vehicle door outer plate

Core Design Contradiction:

Ease of manufactureVSManufacturing precision

Solution Approach 1:

The tolerance absorption assembly is designed beforehand to cushion and absorb mounting errors and element tolerances. It preemptively compensates for manufacturing variations in mounting holes, enabling uniform gaps and flushes to be achieved even when larger manufacturing tolerances are present in the mounting holes

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

Solution Approach 2:

The tolerance absorption assembly acts as an intermediary that decouples the relationship between mounting hole precision and final handle positioning precision. It allows easier manufacturing of mounting holes while ensuring high precision in the final assembly through error absorption

Inventive Principle:

Principle #24Intermediary (Mediator)
