Solution Overview

Problem

Existing detection devices for relative position between movable elements are often complex, unsightly, and increase the cost of the structure due to the need for attachment to the elements being monitored.

Innovation Solution

A detection device integrated into one of the elements, where the relative position is detected by an electrical circuit that opens and closes based on the position of the elements, utilizing conductive parts within the circuit to transmit information without external attachment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a detection device is attached to the elements being monitored, then the relative position can be detected, but the structure becomes more complex, unsightly, and expensive

Engineering Contradiction:
Improvedetection capabilityVSAvoidstructural complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges the detection device with one of the elements being monitored (either the movable element or the fixed element) by integrating conductive parts directly into the element's structure. This eliminates the need for separate attachment components, thereby reducing structural complexity while maintaining detection capability. The conductive parts become part of the element itself rather than external attachments.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The element being monitored serves dual functions: it performs its primary mechanical function (e.g., moving, supporting) and simultaneously serves as part of the detection circuit through its conductive parts. This multi-functionality reduces the need for separate detection components, simplifying the overall structure while enabling position detection.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Reliability

If a detection device is attached to the elements being monitored, then the relative position can be detected, but the appearance becomes unsightly

Engineering Contradiction:
Improvedetection capabilityVSAvoidaesthetic appearance
Core Design Contradiction:
ReliabilityVSShape

Solution Approach 1:

By integrating the conductive detection parts directly into the element's structure rather than attaching separate detection devices, the patent eliminates visible external components. The detection functionality becomes invisible or indistinguishable from the element itself, preserving aesthetic appearance while maintaining detection capability.

Inventive Principle:
Principle #5Merging (Combining)

3Reliability

If a detection device is attached to the elements being monitored, then the relative position can be detected, but the cost increases

Engineering Contradiction:
Improvedetection capabilityVSAvoidmanufacturing cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The patent combines the detection functionality with the existing elements, eliminating the need for separate detection device components and their associated manufacturing and assembly costs. The conductive parts are integrated into the element's structure, reducing material costs and simplifying manufacturing processes.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The element serves multiple functions (mechanical function + detection function), which reduces the total number of components needed in the system. This consolidation reduces manufacturing costs by eliminating the need to produce and assemble separate detection devices.

Inventive Principle:
Principle #6Universality (Multi-functionality)
