Solution Overview

Problem

Existing heating device control panels are difficult to service as they require tilting or removal, which obstructs visual inspection of display elements and necessitates unscrewing screws and brackets, complicating assembly and disassembly.

Innovation Solution

The control panel is mechanically and detachably fastened to the heater housing using integrated fastening means such as elastic fasteners, bosses, partitions, and slotted openings, allowing for secure positioning without additional fasteners or tools, enabling a tilted and service position for improved access.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of repair

If the control panel is fixed using hinges and screws, then the control panel can be tilted for service access, but visual inspection of display elements becomes impossible and assembly/disassembly requires multiple fasteners

Engineering Contradiction:
Improveservice accessVSAvoidvisual inspection
Core Design Contradiction:
Ease of repairVSEase of operation

Solution Approach 1:

The control panel is designed to be rotatable relative to the housing, allowing it to transition between a working position (flush with housing front surface) and a service position (rotated outward). This dynamic positioning enables service access while maintaining visual inspection capability throughout the rotation range.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The fastening function and the positioning function are merged into a single integrated mechanism. The fastening means includes features that both secure the control panel to the housing and enable its rotation, eliminating the need for separate hinge mechanisms and multiple screws.

Inventive Principle:
Principle #5Merging (Combining)

2Ease of repair

If the control panel is removed for service or replacement, then access to rear components is improved, but assembly and disassembly becomes complicated due to screws and brackets

Engineering Contradiction:
Improvecomponent accessVSAvoidfastening mechanism
Core Design Contradiction:
Ease of repairVSDevice complexity

Solution Approach 1:

Traditional fastening elements such as separate screws, brackets, and hinge components are extracted and replaced by an integrated fastening mechanism built into the control panel structure itself. This simplifies the overall assembly to a single detachable unit.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The control panel incorporates self-contained fastening means with elastic elements that automatically engage with the housing during assembly and can be easily released during disassembly without requiring external tools or complex manipulation of multiple fasteners.

Inventive Principle:
Principle #25Self-service

3Ease of repair

If the control panel is tilted for service intervention, then access to inner areas is improved, but display elements become invisible and directed downwards

Engineering Contradiction:
Improveinner area accessVSAvoiddisplay visibility
Core Design Contradiction:
Ease of repairVSLoss of information

Solution Approach 1:

The control panel's rotatable design allows it to maintain an upright orientation relative to the service person even when the housing is tilted or positioned in difficult-to-reach locations. The display elements remain vertically oriented and visible throughout the rotation range, solving the visibility problem while providing service access.

Inventive Principle:
Principle #15Dynamics
