Solution Overview

Problem

Existing room service tables in hotels face challenges with limited legroom due to food warmers, which obstruct comfortable seating and require separate storage, taking up additional space when collapsed.

Innovation Solution

A room service table with a pivoting and tilting table top mechanism, integrated with an insulated drawer serving as a food warmer, allowing the table to nest for storage without removing the warmer, utilizing a lift mechanism and gas strut for efficient space utilization.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If a food warmer is placed on the room service table, then food can be kept warm, but leg room is limited and storage space increases

Engineering Contradiction:
Improvefood temperatureVSAvoidleg room area
Core Design Contradiction:
TemperatureVSArea of stationary object

Solution Approach 1:

The patent combines the food warmer function directly into the table structure by integrating a heating element within the table top, eliminating the need for a separate food warmer box. This merging of functions resolves the contradiction by providing food warming capability while maintaining adequate leg room, as the heating element occupies minimal space within the table structure itself rather than adding external volume.

Inventive Principle:
Principle #5Merging (Combining)

2Temperature

If a food warmer is placed on the room service table, then food can be kept warm, but storage space increases when collapsed

Engineering Contradiction:
Improvefood temperatureVSAvoidstorage volume
Core Design Contradiction:
TemperatureVSVolume of stationary object

Solution Approach 1:

The heating element is integrated within the table top structure, merging the food warming function into the existing table volume. This eliminates the need for a separate food warmer box that would need to be stored separately, thereby reducing the total storage volume when the table is collapsed.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The table features a nested design where the table top can be folded or collapsed into the table frame structure. The integrated heating element is positioned within the table top, allowing the entire assembly to be compacted efficiently for storage, minimizing the volume occupied during storage.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Strength

If the table top is made rigid for stability, then structural strength is improved, but adaptability for different positions is reduced

Engineering Contradiction:
Improvetable structural strengthVSAvoidtable top position adaptability
Core Design Contradiction:
StrengthVSAdaptability or versatility

Solution Approach 1:

The table top is designed with movable joints connecting it to the table frame, allowing the table top to be adjusted to different positions and angles. This dynamic design enables the table top to adapt to various configurations while maintaining structural strength through properly engineered joint connections, resolving the contradiction between rigidity and adaptability.

Inventive Principle:
Principle #15Dynamics

AI summary

A room service table, including a table top having two opposing edges; at least two opposing legs adjacent a respective opposing edge, for supporting the table top, the legs having wheels for rolling the table along a surface; a drawer located underneath of the table top for receiving food for room service delivery; wherein the table top is moveably connected to the opposing legs, and whereby the table top and drawer can be tilted upwards with respect to both of the opposing legs to allow nesting together of two or more like room service tables.
